What is always necessary throughout efforts to prevent and control COVID-19 and other infectious diseases? A physical containment strategy and public mobilization and management

Characteristics of pediatric patients claimed with acute upper respiratory infection during otorhinolaryngology consultations: A descriptive study of a large Japanese medical claims database

This study aimed to clarify other diseases claimed simultaneously with acute upper respiratory infection (URI), antibiotic prescriptions, and examinations associated with infectious diseases in pediatric patients with acute URI insurance claims at otorhinolaryngology outpatient visits. Pediatric patients who visited an otolaryngology department between 2019 and 2021 and were definitively diagnosed with URI were selected using a large Japanese medical claims database. Patient backgrounds, antibiotic use, and examinations were descriptively evaluated. In total, 8010 patients were included in the analysis. The median number (interquartile range) of diseases claimed in the same month as acute URI was 4 (3-6). Only 519 (6.5 %) patients were claimed as acute URI alone. Regardless of the prescription of antibiotics, the most commonly redundantly claimed disease in these patients was allergic rhinitis, followed by acute bronchitis, acute sinusitis, and earwax impaction. The frequently prescribed antibiotics were third-generation cephalosporins, macrolides, and penicillins with extended-spectrum, including amoxicillin which was recommended by the Japanese manual; the proportion of patients with examinations was low (2.9-21.7 %). Among patients with acute URI, diagnoses requiring antibiotics were also claimed; therefore, when evaluating acute URI using the Japanese medical claims database, care must be taken in patient selection. Moreover, the implementation rate of examinations necessary for diagnosis was low, so there is an urgent need to develop an environment where examinations can be conducted in outpatient settings.

Immunity debt: Hospitals need to be prepared in advance for multiple respiratory diseases that tend to co-occur

As SARS-CoV-2 transitions from a pandemic to an endemic presence, a significant rise in respiratory diseases such as influenza and Mycoplasma pneumonia is challenging healthcare systems weakened by the impact of COVID-19. This commentary examines the global resurgence of respiratory pathogens, heightened by the post-pandemic "immunity debt", through an analysis of WHO surveillance data and national health reports. Findings reveal a substantial increase in respiratory illnesses, notably among children, compounded by a shortage of pediatricians and growing antimicrobial resistance. This underscores the need to improve hospital preparedness, optimize clinical responses, and enhance public health strategies to effectively navigate the impending peak of concurrent respiratory infections.

For COVID-19, what are the priorities of normalized prevention and control strategies?

The COVID-19 pandemic has ravaged the world for three years. Most countries have adjusted policies and strategies in response to the burden of COVID-19. The severity of COVID-19 seems to be diminishing as the case fatality rate has declined and the number of vaccinated people has increased markedly. Given the large population worldwide, we need to pay attention to the continuing COVID-19 burden. Globally, the number of cases remains at a certain level, and the number of cases is still increasing in China. We also need to deal with shortages of medical resources, antipyretics, and home nursing facilities. SARS-CoV-2 will coexist with humans for a long time, and predicting viral mutations and pandemic trends will be difficult. The reform of the whole public health system is imperative. A comprehensive surveillance system should be created to determine the proportion of various pathogens and to guard against mixed infections of respiratory infectious diseases. A comprehensive response mechanism, including preventive measures and medical treatments, should be created as soon as possible to monitor the status of the epidemic and to deal with the long-term health burden of SARS-CoV-2.

The role of influenza in the era of COVID-19: Can we forget it?

COVID-19 has been a topic of interest since a pandemic struck in 2019. The morbidity of influenza tended to decrease due to the measures to prevent COVID-19. Indeed, influenza seems to be "ignored" in this era of COVID-19. However, influenza has not disappeared from the scene. Presented here are two examples of recent influenza epidemics in China and Australia. Possible interactions between COVID-19 and influenza are discussed. Measures against COVID-19 may reduce contact with influenza, subsequently reducing adaptive immunity against influenza in the general population. Influenza might not be center stage right now, but insufficient adaptive immunity in the population may potentially trigger a future influenza pandemic. Coinfection with COVID-19 and influenza might potentially be a thorny problem. Hence, influenza cannot be ignored. Governments around the world should take measures to prepare for a possible influenza pandemic in the future.

From SARS to the Omicron variant of COVID-19: China's policy adjustments and changes to prevent and control infectious diseases

The COVID-19 pandemic has been the biggest public health crisis in a century. Since it was initially reported in 2019, the duration and intensity of its impacts are still in serious question around the world, and it is about to enter its third year. The first public health revolution failed to achieve its ultimate targets, as previously contained infectious diseases seem to have returned, and new infectious diseases continue to emerge. The prevention and control of infectious diseases is still a public health priority worldwide. After SARS, China adjusted a series of its infectious disease policies. In order to ensure the effectiveness and implementation of prevention and control interventions, the government should integrate the concept of public health. Perhaps we need a global public health system at the government level to fight the potential threat of infectious disease. This system could include multifaceted strategies, not just specific prevention and control interventions, and it could also be a comprehensive system to ensure unimpeded communication and cooperation as well as sustainable development.
