Abstract
The development of safe and effective vaccines in a record time after the emergence of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a remarkable achievement, partly based on the experience gained from multiple viral outbreaks in the past decades. However, the Coronavirus Disease 2019 (COVID-19) crisis also revealed weaknesses in the global pandemic response and large gaps that remain in our knowledge of the biology of coronaviruses (CoVs) and influenza viruses, the 2 major respiratory viruses with pandemic potential. Here, we review current knowns and unknowns of influenza viruses and CoVs, and we highlight common research challenges they pose in 3 areas: the mechanisms of viral emergence and adaptation to humans, the physiological and molecular determinants of disease severity, and the development of control strategies. We outline multidisciplinary approaches and technological innovations that need to be harnessed in order to improve preparedeness to the next pandemic.

Transbound Emerg Dis 2021; 69:e344-e355. [PMID: 34464033 DOI: 10.1111/tbed.14307] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 08/28/2021] [Accepted: 08/29/2021] [Indexed: 12/14/2022]
Abstract
The current COVID-19 pandemic highlights the need for zoonotic infectious disease surveillance. Avian influenza virus (AIV) poses a significant threat to animal and public health due to its pandemic potential. Virus-contaminated water has been suggested as an important AIV spread mechanism among multiple species. Nevertheless, few studies have characterized the global AIV subtype diversity and distribution in environmental water. Therefore, this study aims to provide an updated descriptive and phylogenetic analysis of AIVs isolated in water samples from high risk-sites for influenza outbreaks (i.e. live bird markets, poultry farms, and wild bird habitats) on a global scale. The descriptive analysis evidenced that 21 subtypes were reported from nine countries between 2003 and 2020. Fourteen AIV subtypes were solely reported from Asian countries. Most of the viral sequences were obtained in China and Bangladesh with 47.44% and 23.93%, respectively. Likewise, the greatest global AIV subtype diversity was observed in China with 12 subtypes. Live bird markets represented the main sampling site for AIV detection in water samples (64.1%), mostly from poultry cage water. Nevertheless, the highest subtype diversity was observed in water samples from wild bird habitats, especially from the Izumi plain and the Dongting Lake located in Japan and China, respectively. Water from drinking poultry troughs evidenced the greatest subtype diversity in live bird markets; meanwhile, environmental water used by ducks had the highest number of different subtypes in poultry farms. Maximum-likelihood phylogenetic trees of hemagglutinin (HA) and neuraminidase (NA) genes showed that some sequences were closely related among different poultry/wild bird-related environments from different geographic origins. Therefore, the results suggest that even though the availability of gene sequences in public-access databases varies greatly among countries, environmental AIV surveillance represents a useful tool to elucidate potential viral diversity in wild and domestic bird populations.

[PMID: 31928706 DOI: 10.1016/j.vetmic.2019.108572] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Revised: 12/29/2019] [Accepted: 12/30/2019] [Indexed: 12/25/2022]
Abstract
Despite improvement of human and avian influenza surveillance, swine influenza surveillance in sub-Saharan Africa is scarce and pandemic preparedness is still deemed inadequate, including in Burkina Faso. This cross-sectional study therefore aimed to investigate the (past) exposure of pigs to influenza A viruses. Practices of people with occupational contacts with pigs and their knowledge on influenza A were investigated in order to formulate future prevention guidelines. In 2016-2017, pig nasopharyngeal swabs and sera were collected and screened for the presence of influenza virus by RT-PCR or of anti-influenza antibodies by competitive ELISA. Seropositive samples were further characterized in virus microneutralization assays against human and swine H1N1 virus strains. Nasopharyngeal swabs were obtained from people with occupational contact with pigs and screened similarly. Demographic data as well as practices related to their profession were recorded. No influenza A virus was detected in nasopharyngeal swabs in humans (n = 358) or in pigs (n = 600). Seroprevalence in pigs reached 6.8 % (41/600) and seropositive animals were found in 50.0 % of extensive settings (10/20) and 19.0 % of (semi-)intensive farms (4/21). All positive sera reacted against the pandemic H1N1/2009 strain, while seropositivity against two Eurasian avian-like and one American swine H1N1 strains and individual titers were lower. These results suggested exposure to pandemic H1N1/2009 virus and cross-reactivity to other H1N1 strains. Farmers with higher frequency of contact to pigs, absence of protective equipment and lack of knowledge on zoonoses are likely key players in driving human-to-swine virus transmission.
