Abstract
BACKGROUND Environmental and lifestyle factors play an etiological role in the pathogenesis of different glomerular diseases. Thus, exploring the epidemic characteristics of renal disease in different nationalities and regions is important. MATERIALS AND METHODS Patients who underwent renal biopsy from October 2008 to October 2022 were included. The proportion and change tendency of glomerular diseases and the differences between the sexes and different ages and races were analyzed. RESULTS There were 15,146 cases of glomerular diseases (98.5%), involving 7538 males (49.8%) and 7608 females (50.2%). The mean age was 37.0 years (range 0-80 years). The proportion of membranous nephropathy (MN) and diabetic nephropathy (DN) showed an increased trend. The most common primary glomerulonephritis (PGN) was IgA nephropathy (IgAN, 44.6%), followed by minimal-change disease (MCD, 24.3%) and MN (15.4%). Lupus nephritis (LN, 30%) accounted for the largest proportion of SGNs, followed by Henoch-Schonlein purpura nephritis (HSPN, 20.9%) and DN (19.8%). Compared with adults aged 18-60 years old, MCD and HSPN were more common in children and MN and DN in elderly individuals, statistically significant differences. Additionally, the sex and age distribution of PGN and SGN between the Tibetan and Han populations differed significantly, whereby LN was higher in the Han population and HSPN in the Tibetan population. CONCLUSION The distribution of glomerular diseases showed age, sex and race differences. This research will be beneficial for providing epidemiological evidence for clinical diagnosis, disease prevention and public health decision-making.

Abstract
Objective This study described the epidemic characteristics of varicella in Dalian from 2009 to 2019, explored the fitting effect of Grey model first-order one variable( GM(1,1)), Markov model, and GM(1,1)-Markov model on varicella data, and found the best fitting method for this type of data, to better predict the incidence trend. Methods For this Cross-sectional study, this article was completed in 2020, and the data collection is up to 2019. Due to the global epidemic, the infectious disease data of Dalian in 2020 itself does not conform to the normal changes of varicella and is not included. The epidemiological characteristics of varicella from 2009 to 2019 were analyzed by epidemiological descriptive methods. Using the varicella prevalence data from 2009 to 2018, predicted 2019 and compared with actual value. First made GM (1,1) prediction and Markov prediction. Then according to the relative error of the GM (1,1), made GM (1,1)-Markov prediction. Results This study collected 37,223 cases from China Information System for Disease Control and Prevention's “Disease Prevention and Control Information System” and the cumulative population was 73,618,235 from 2009 to 2019. The average annual prevalence was 50.56/100000. Varicella occurred all year round, it had a bimodal distribution. The number of cases had two peaks from April to June and November to January of the following year. The ratio of males to females was 1.17:1. The 4 to 25 accounted for 60.36% of the total population. The age of varicella appeared to shift backward. Students, kindergarten children, scattered children accounted for about 64% of all cases. The GM(1,1) model prediction result of 2019 would be 53.64, the relative error would be 14.42%, the Markov prediction result would be 56.21, the relative error would be 10.33%, and the Gray(1,1)-Markov prediction result would be 59.51. The relative error would be 5.06%. Conclusions Varicella data had its unique development characteristics. The accuracy of GM (1,1)—Markov model is higher than GM(1.1) model and Markov model. The model can be used for prediction and decision guidance. Supplementary Information The online version contains supplementary material available at 10.1186/s12889-022-12898-3.

Abstract
Objective: To describe the epidemic characteristics of stomach cancer mortality in Qidong between 1972 and 2016. Methods: The cancer registry data of stomach cancer death and population during 1972-2016 in Qidong was collected. The mortality of crude rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), 35-64 years truncated rate, 0-74 years cumulative rate, cumulative risk, percentage change (PC), annual percent change (APC) were calculated. Results: During 1972-2016, a total of 15 863 (male: 10 114, female: 5 749) deaths occurred attributed to stomach cancer, accounting for 16.04% of all cancers, with CR of 31.37/100 000 (CASR: 12.97/100 000, WASR: 21.39/100 000). The truncated rate of 35-64, cumulative rate of 0-74, and cumulative risk were 28.86/100 000, 2.54%, and 2.51%, respectively. For male, the CR, CASR, WASR were 40.53/100 000, 17.98/100 000, 30.13/100 000, respectively, and for female, the CR, CASR, WASR were 22.45/100 000, 8.52/100 000, 13.92/100 000, respectively. Age-specific mortality analysis showed that the mortality of each age group under 25-year-old group was less than 1/100 000. The CR increased with age. The 50-year-old group reached and exceeded the average mortality of the population, and more than 80-year-old group reached the peak of death. During 1972-2016 in Qidong, The PCs in CR, CASR, and WASR of stomach cancer were 55.43%, -52.02%, -43.60%. The APC were 0.54%, -2.30%, -2.08%, respectively. Period mortality analysis showed that except for the 75-year-old group, the mortality of stomach cancer decreased significantly. Conclusions: The crude mortality of stomach cancer increases slightly in Qidong, while the CASR and WASR decrease significantly. However, stomach cancer is still one of the malignant tumors that most affect health and seriously threat lives.

Abstract
Blastocystis is an anaerobic intestinal protozoan parasite found in humans and many kinds of animals that mainly causes diarrhea, abdominal pain and other clinical symptoms. At present, research on the prevalence and subtype diversity of Blastocystis in domestic pigeons is very limited. The purpose of this study was to detect the infection rate and gene subtype distribution of Blastocystis in domestic pigeons in Henan Province, Central China, to provide a foundation for preventing and controlling Blastocystis in domestic pigeons. Fecal DNA was extracted from 504 fresh fecal samples of pigeons collected from 4 areas in Henan Province, Central China. All DNA samples were investigated by polymerase chain reaction (PCR), and positive samples were sequenced to analyze the gene subtypes based on small ribosomal subunit (SSU rRNA) gene. The overall infection rate of Blastocystis in pigeons in Henan Province was 7.7% (39/504). Four subtypes (STs) of Blastocystis were identified including ST1 (2/39, 5.1%), ST3 (16/39, 41.0%), ST4 (1/39, 2.6%) and ST7 (20/39, 51.3%), all of which belonged to zoonotic subtypes, and ST7 was the dominant gene subtype. The results show that Blastocystis infection is common in domestic pigeons in Henan Province, Central China, and the pathogen were zoonotic subtypes. Particular attention should be given to reducing the risk of transmission of Blastocystis from domestic pigeons to humans.

Abstract
BACKGROUND Tuberculosis (TB) is a serious public health problem in China. There is evidence to prove that meteorological factors and exposure to air pollutants have a certain impact on TB. But the evidence of this relationship is insufficient, and the conclusions are inconsistent. METHODS Descriptive epidemiological methods were used to describe the distribution characteristics of TB in Shijiazhuang in the past five years. Through the generalized linear regression model (GLM) and the generalized additive model (GAM), the risk factors that affect the incidence of TB are screened. A combination of GLM and distribution lag nonlinear model (DLNM) was used to evaluate the lag effect of environmental factors on the TB. Results were tested for robustness by sensitivity analysis. RESULTS The incidence of TB in Shijiazhuang showed a downward trend year by year, with seasonality and periodicity. Every 10 μg/m3 of PM10 changes, the RR distribution is bimodal. The first peak of RR occurs on the second day of lag (RR = 1.00166, 95% CI: 1.00023, 1.00390); the second risk period starts from 13th day of lag and peaks on15th day (RR = 1.00209, 95% CI: 1.00076, 1.00341), both of which are statistically significant. The cumulative effect of increasing 10 μg/m3 showed a similar bimodal distribution. Time zones where the RR makes sense are days 4-6 and 13-20. RR peaked on the 18th day (RR = 1.02239, 95% CI: 1.00623, 1.03882). The RR has a linear relationship with the concentration. Under the same concentration, the RR peaks within 15-20 days. CONCLUSION TB in Shijiazhuang City showed a downward trend year by year, with obvious seasonal fluctuations. The air pollutant PM10 increases the risk of TB. The development of TB has a short-term lag and cumulative lag effects. We should focus on protecting susceptible people from TB in spring and autumn, and strengthen the monitoring and emission management of PM10 in the atmosphere.

Abstract
Objective: To analyze the epidemic characteristics and spatio-temporal distribution of hemorrhagic fever with renal syndrome (HFRS) in Guangzhou from 2010 to 2019 and provide a basis for prevention and control strategies. Methods: The data of HFRS was from National Disease Reporting Information System and the epidemic investigation. A descriptive analysis was used. OpenGeoDa 1.2.0 software was used for global spatial autocorrelation and local spatial autocorrelation analysis. SatScan 9.6 software was used for detecting the hot spot area in time and space. ArcGIS 10.2 software was used for map visualization. Results: 1 298 cases of HFRS were reported, and three patients died in Guangzhou in 2010-2019. The annual incidence rate was 0.99/100 000. The proportion of 21-50 years old cases accounted for 70.88% and the male to female ratio was 2.98∶1. Most patients were house workers or unemployed, accounting for 31.28%, followed by business servants (accounting for 17.33%). The incidence peak in spring and winter accounted for 33.74% and 26.35% of the year. All districts reported cases in recent ten years. A total of 407 cases had been reported in Haizhu district, accounting for 31.36% of the total number of cases in the whole city. The annual incidence rate was 2.52/100 000. The number of reported cases and the annual incidence rate were the highest in Guangzhou. The clustered area showed that there was spatio-temporal clustering in Guangzhou. The aggregation area was mainly concentrated in the urban villages adjacent to Wan-mu orchard and the Haizhu Lake Wetland Park in Haizhu district (logarithmic likelihood ratio was 44.08, P<0.001). Conclusions: The prevalence and concentration of HFRS in winter and spring Guangzhou city from 2010 to 2019, showed a high incidence. Young and middle-aged men engaged in domestic and unemployed, and commercial services appeared the main risk groups. The urban-rural junction with many immigrants and low health environment, streets adjacent to Wan-mu orchard, and the Haizhu Lake Wetland Park in Haizhu district were the important regions for preventing and controlling HFRS. The government should formulate prevention and control measures to curb the rise and spread of the HFRS epidemic.

Abstract
Objective: To compare epidemic characteristics between severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19). Methods: The general information, including epidemiological and clinical data of the confirmed cases during the epidemic period of the two infectious diseases was collected. The data of SARS in Guangzhou was derived from the technical files of Guangzhou Center for Disease Control and Prevention (GZCDC), including the statistical report and brief report of the epidemic situation (from January 2 to May 11, 2003);The data of COVID-19 in Wuhan was derived from the epidemic data published by Wuhan health and Health Committee's official website and other publicly reported documents (from December 9, 2019 to March 11, 2020). Descriptive analysis was used for a comparativeanalysis of the time and age characteristics, the number of cases, basic reproduction number (R0), proportion of medical staff in confirmed cases (%), crude mortality, etc. Results: A total of 1 072 cases of SARS in Guangzhou were included in the study. The incidence ratio of male to female was 1∶1.26. 43 cases of death were reported with a mortality rate of 4.01%. The median age was 36 years old. The proportion of medical staff in the early stage of the epidemic was 29.04% (88 cases). As to COVID-19 in Wuhan, a total of 49 978 cases were included, The incidence ratio of male to female was 1.04∶1. The 2 423 cases of death were reported with a mortality rate of 4.85%. The median age was 56 years old. The proportion of medical staff in the early stage of the epidemic was 30.43% (42 cases). Conclusion: The COVID-19 in Wuhan has the characteristics of high incidence and wide population. However, the epidemic situation is falling rapidly, and the prevention and control strategy needs to be adjusted timely. The prevention and control of nosocomial infection should be addressed in future.

OBJECTIVE To investigate the epidemiological characteristics of human echinococcosis in Inner Mongolia Autonomous Region, so as to provide evidence for the development of the precision control strategy of human echinococcosis in the region. METHODS A sampling survey of human echinococcosis was conducted in 28 banners (counties, districts) of Inner Mongolia Autonomous Region from 2012 to 2017, and the epidemiological characteristics were descriptively analyzed. RESULTS A total of 90 058 residents were examined for echinococcosis in 28 banners (counties, districts) of Inner Mongolia Autonomous Region from 2012 to 2017, and 71 patients were detected with echinococcosis, with a detection rate of 0.08%. No echinococcosis cases were identified in 8 banners (counties), and there were 6 banners (counties) with echinococcosis prevalence of 0.1% to 1%, and 14 with prevalence of 0 to 0.1%. The echinococcosis prevalence was significantly greater in women (0.11%) than in men (0.05%) (χ2 = 10.09, P = 0.001), and the highest prevalence was detected in patients at ages of over 50 years (38 cases, 53.52%). In addition, the highest echinococcosis prevalence was detected in herdsmen (0.14%), or in primary school children (0.13%). CONCLUSIONS Human echinococcosis is widely, but lowly prevalent in Inner Mongolia Region, with a diverse density of infections. Echinococcosis has remarkable characteristics of regional and population clusters in Inner Mongolia Region, and the management of echinococcosis requires to be reinforced in key regions and populations.

Abstract
Objective: To study the epidemiological characteristics and mixed infection of adenovirus in acute respiratory tract infections in Shanghai from 2015 to 2019, and to provide scientific basis for the prevention and control of adenovirus. Methods: Acute respiratory tract infections were collected from 3 hospitals in Shanghai from 2015 to 2019. Relevant information was registered and respiratory specimens were sampled for detection of respiratory pathogens by multiplex PCR. Results: A total of 1 543 cases of acute respiratory tract infection were included. The positive rate of adenovirus was 2.92%(45/1 543), the positive rates of influenza like illness (ILI) and severe acute respiratory illness (SARI) were 2.74%(29/1 058) and 3.30%(16/485), respectively. The positive rate of ILI during January-May 2019 was 5.43%(7/129), higher than that in the same period of 2015- 2018 (0.52%-4.48%) (Fisher's exact test value=8.92, P=0.036). The incidence of adenovirus-positive cases was mainly distributed in the first and second quarters, accounting for 62.22% (28/45). The difference of the incidence of adenovirus-positive cases in each quarter was significant (χ(2)= 12.52, P=0.006). The positive rate in the second quarter was highest (6.03%), which was higher than that in other quarters (1.89%-2.93%). There were significant differences among different age groups (χ(2)=16.94, P=0.001), and the positive rate decreased with age (χ(2)=10.16, P=0.001). The positive rate of 13-19 years old group (9.43%) was higher than that of other age groups (1.48%-4.81%). The positive rate of student group (12.07%) was higher than that of other occupations (2.61%). The difference was systematic (χ(2)=11.53, P=0.001). Mixed infection accounted for 31.11% (14/45) of 45 adenovirus positive cases. The mixed infection rates of ILI and SARI were 34.48% (10/29) and 25.00% (4/16), respectively. Among 14 cases of mixed infection, the main mixed infection pathogens of adenovirus were influenza A virus and coronavirus. Conclusion: Adenovirus surveillance should be further strengthened in adolescents with a focus on students and other key groups in the second quarter.

Abstract
Background Health care workers have a high risk of occupational exposure. However, the risk of occupational exposure for pediatric health care workers has not been acknowledged in previous studies. The purpose of this study was to investigate the occupational exposure rate of pediatric health care workers in Chinese public hospitals, to explore risk factors for occupational exposure, and to put forward corresponding countermeasures to reduce occupational exposure of pediatric health care workers and protect their physical and mental health. Methods A cross-sectional study was conducted with pediatric health care workers in 43 hospitals in 15 provinces in eastern, central, and western China between July and October 2018. With this sample, we computed the descriptive statistics of the demographic characteristics, calculated the frequency of various types of occupational exposure, and tested risk factors for occupational exposure using a chi-squared test and binary logistic regression analysis. Results Most respondents were nursing staff (61.1%) and workers with a low-ranking professional title (50.5%). The most common style of occupational exposure in our sample was a hazard in the work environment (62.6%). Notably, physicians were less likely to experience occupational exposure than nurses (OR = 0.320, 95% CI = 0.241, 0.426). Meanwhile, pediatric health care workers who interpreted the doctor-patient relationship as harmonious (OR = 0.304, 95% CI = 0.152, 0.607) were less likely to suffer occupational exposure. Conclusion Pediatric health care workers in Chinese public hospitals have a high occupational exposure risk and the risk factors are complex and diverse. The state, society, hospitals should acknowledge this issue and develop strategies to protect the physical and mental health of pediatric health care workers.

Abstract
BACKGROUND Hand, foot and mouth disease (HFMD) is the highest incidence of infectious diseases in China. Shantou is one of the most infected cities. Therefore, it is necessary for us to understand the epidemic characteristics and distribution trend of HFMD in Shantou. The purpose of this study is to investigate the spatial epidemiological characteristics of HFMD and analyse its spatial autocorrelation. METHOD We collated and summarised the data of HFMD in Shantou from 2010 to 2015. SaTScan software and Moran's I were used to analyse the spatial correlation of HFMD, and the results were presented in ArcMap. RESULTS The distribution of HFMD in Shantou was of a seasonal trend, mainly concentrating during May and June. Children under 5-years-old were the main group of cases of HFMD, accounting for 92.46%. The proportion of infected children, especially those aged zero to 1, was the largest in each year, accounting for 45.62%, meaning that smaller children were more susceptible to HFMD. The number of male patients with HFMD was greater than that of females (1.78:1, male: female). With regard to the potential impact of patients' living style on the incidence rate of HFMD, this study revealed that scattered children were the dominant infected population, accounting for as much 84.49% of cases. The incidence of HFMD was unevenly distributed among streets. The incidence interval of streets was in a range of 13.76/100,000 to 1135.19/100,000. Spatial autocorrelation analysis showed that there was no global spatial correlation in Shantou, except in 2013. The results of local spatial autocorrelation analysis showed that H-H correlation existed in the high incidence local area of Shantou. CONCLUSIONS The incidence of HFMD across the various streets in Shantou not only varied widely but also represented local autocorrelation. Attention, as well as prevention and control measures, should be focused on those high-incidence areas, such as the Queshi street, Zhuchi street and Xinjin street.

Abstract
Objective: To study the spatial and temporal mode of infectious TB transmission in Guangxi Zhuang Autonomous Region (Guangxi). Methods: Data related to infectious TB case (Include smear and/or culture positive patients) in Guangxi were collected from the National Notifiable Disease Reported System (NNDRS) from 2010 to 2015. Spatial-temporal analysis and prediction were performed by SaTScan 7.0.2, GeoDa 1.8.12, R program v 3.3.1 and SPSS 19.0 software, using the time series model, Moran's I global and local spatial autocorrelation (Empirical Bayes adjustment). Kulldorff 's space-time scan statistics displayed by R software was used to identify the temporal and spatial trend of TB. Results: The total number of infectious TB cases, collected from NNDRS was 76 151, and showing a decreasing trend on annual incidence (value of Chi-square for Linear trend=3 464.53, P-value=0.000). The forecast value of TB cases in 2016 was 7 764 (4 971-10 557), with peak in March, analyzed through the Winters'multiplicative model. The Moran's I global Statistics was greater than 0 (0.257-0.390). TB cluster seemed to have been existed for several years. The most significant hot spots seemed to be mainly located in the central and western parts of Guangxi, shown by local spatial autocorrelation statistics and the result from space-time scanning.Counties or districts that located in the east parts of Guangxi presented the low-low relation (significant cold spots). The situation of infectious TB seemed migratory. Conclusions: Our data showed an annual decreasing trend of incidence on infectious TB with temporal concentration in spring and summer. Main clusters (hot spots) were found to be located in the central and western parts of Guangxi. Hopefully, our findings can provide clues to uncover the real mode of TB transmission at the molecular-biological level.

Abstract
Objective: To explore the current prevalence of dyslipidemia in adult population of 9 provinces of China and the epidemic characteristics of this disease. The potential influence of social economic development on dyslipidemia was also observed. Methods: Present research data are derived from the result of the investigation about survey on health and nutrition in China in 2011, in which multistage stratified cluster random sampling method was adopted to investigate the 24 345 individuals in 216 communities from 9 provinces in China and 10 242 blood samples were collected. In this research, 8 669 blood samples of people over 18 years old were selected for final analysis. After adjustment of age, the percentage of dyslipidemia patients in Chinese adults was calculated. Results: The percentage of dyslipidemia in Chinese adults is 39.91% (3 460/8 669). The percentage of dyslipidemia at the age of 18-24, 35-44, 45-59 and over 60 years old were 30.25% (373/1 233),37.19% (774/2 081), 44.22% (1 304/2 949) and 41.94%(1 009/2 406),respectively (χ(2)=333.02, P<0.01); the percentage of dyslipidemia in male and female population was 51.11% (1 956/3 827) and 31.06%(1 504/4 842), respectively (χ(2)=60.35, P<0.01); the percentage of dyslipidemia in urban residents and rural residents was 42.56% (1 144/2 687) and 38.72%(2 316/5 982), respectively (χ(2)=11.72, P<0.01);the percentage of dyslipidemia in high-GDP regions and low-GDP regions was 43.04% (1 567/3 641) and 37.65% (1 893/5 028), respectively (χ(2)=25.57, P<0.01) .The prevalence of adult hypercholesterolemia in Chinese adult is 9.01% (781/8 669), the prevalence of borderline increased cholesterol is 22.54% (1 954/8 669), the prevalence of hypertriglyceridemia is 27.02% (2 342/8 669), the prevalence of lower high-density lipoproteinemia is 14.36% (1 245/8 669) and the prevalence of increased low-density lipoproteinemia was 10.23% (887/8 669). All prevalence rates are significantly higher compared to the 2005 survey results. Conclusion: The prevalence of dyslipidemia in Chinese adults is high and the prevalence increases in a fast pace. The current situation of dyslipidemia in Chinese adults is critical and targeted strategies should be applied to control the dyslipidemia in adult Chinese population.

Abstract
Objective: To analyze the prevalence and drug resistance of mycoplasma pneumoniae in patients with community-acquired pneumonia during 2011-2015 in Beijing. Methods: Totally 2 272 mycoplasma pneumoniae samples were collected from patients with community-acquired pneumonia in 5 sentinel hospitals during 2011-2015. Mycoplasma pneumoniae were detected by real-time PCR. 142 copies of positive samples with Ct value under 30 were cultured to get the strains so that the genotypes based on the P1 gene sequence and the drug resistance based on the in vitro drug resistance test could be conducted. χ(2) test was used to compare the detection rates of mycoplasma pneumoniae among different age groups and different onset-phase. Results: The positive rate of mycoplasma pneumoniae was 13.6%(308 cases). The positive rate in groups aging (5-14), (15-24) and ≥60 years old were separately 24.4% (67/275), 24.4% (38/156) and 3.9% (28/727) (χ(2)=1.22, P<0.001). The annual detection rate of mycoplasma pneumoniae in 2011-2015 were 14.6% (73/501), 10.2% (36/353), 26.4% (101/383), 10.3% (41/398), 9.0% (57/637),respectively (χ(2)=72.65, P<0.001). Seasonally, the peak of positive rate was between October and December (17.5%, 122/699) and the lowest positive rate was between April and June (8.6%, 43/502). 36 strains were isolated from 142 swabs and 23 (63.9%) were P1-Ⅰ and 13 (36.1%) were P1-Ⅱ by genotyping. All isolates were susceptible to the fluoroquinolones (levofloxacin, ciprofloxacin, and gatifloxacin) and tetracycline. All P1-Ⅱ strains were susceptible to macrolides while most of the P1-Ⅰ strains (22 strains) were macrolide-resistant. Conclusion: People aging (5-14) and (15-24) years old were more susceptible to mycoplasma pneumoniae in patients with community-acquired pneumonia in Beijing between 2011 and 2015. The highest positive rate of mycoplasma pneumoniae was in 2013 and the case distributed in all seasons. The major popular genotype was P1-Ⅰ, whose strains were mostly macrolide-resistant.

Abstract
Significant progress has been made in the prevention, control, and elimination of human parasitic diseases in China in the past 60 years. However, parasitic diseases of poverty remain major causes of morbidity and mortality, and inflict enormous economic costs on societies.In this article, we review the prevalence rates, geographical distributions, epidemic characteristics, risk factors, and clinical manifestations of parasitic diseases of poverty listed in the first issue of the journal Infectious Diseases of Poverty on 25 October 2012. We also address the challenges facing control of parasitic diseases of poverty and provide suggestions for better control.

Abstract
A deterministic model proposed in previous literatures to approximate the well-known Richards model is investigated. However, the model assumption of small initial value for infection size is released in the current manuscript. Taking the advantage of the closed form of solutions, we establish the epidemic characteristics of disease transmission: the outbreak size, the peak size and the turning point for the cumulative infected cases. It is shown that the usual disease outbreak threshold condition (the basic reproduction number R0 is greater than unity) fails to fully guarantee the existence of peaking time and turning point when the initial infection size is not relatively small. The epidemic characteristics not only depend on R0 but also on another index, the net reproduction number R0*.
