Origins of the 2009 H1N1 influenza pandemic in swine in Mexico
Asia is considered an important source of influenza A virus (IAV) pandemics, owing to large, diverse viral reservoirs in poultry and swine. However, the zoonotic origins of the 2009 A/H1N1 influenza pandemic virus (pdmH1N1) remain unclear, due to conflicting evidence from swine and humans. There is strong evidence that the first human outbreak of pdmH1N1 occurred in Mexico in early 2009. However, no related swine viruses have been detected in Mexico or any part of the Americas, and to date the most closely related ancestor viruses were identified in Asian swine. Here, we use 58 new whole-genome sequences from IAVs collecte...

Bird flu researchers get green light to continue work on engineered virus
A voluntary moratorium on research involving lab-created versions of the H5N1 bird flu virus has been liftedResearch on lab-engineered strains of the H5N1 bird flu virus is set to restart a year after the scientists voluntarily paused it to allow for an international public debate on the safest way to proceed.Last year, two teams of scientists in the United States and the Netherlands submitted papers for publication in Science and Nature describing how they had engineered the H5N1 bird flu virus – which kills half of the people it infects but cannot naturally transmit from person to person – to spread more easily betwe...

We Need to Rethink Our Food System to Prevent the Next Pandemic
Once a dangerous new pathogen is out, as we are seeing, it can be difficult if not impossible to prevent it going global. One as contagious as SARS-CoV-2 has the potential to infect the whole of humanity. Eighty per cent of cases may be benign, but with such a large pool of susceptible hosts, the numbers who experience severe illness and die can still be shockingly high. So the only sensible answer to the question, how do we stop this from happening again, is: by doing all we can to prevent such pathogens infecting humans in the first place. And that means taking a long, hard look at our relationship with the natural world...

Variant Influenza: connecting the missing dots
Expert Rev Anti Infect Ther. 2022 Nov 8. doi: 10.1080/14787210.2022.2144231. Online ahead of print.ABSTRACTBACKGROUND: In June 2009, the World Health Organization declared a new pandemic; the 2009 swine influenza pandemic (swine flu). The symptoms of the swine flu pandemic causing strain were comparable to most of the symptoms noted by seasonal influenza.AREA COVERED: Zoonotic viruses that caused the swine flu pandemic and its preventive measures.EXPERT OPINION: As per Centres for Disease Control and Prevention (CDC), the clinical manifestations in humans produced by 2009 H1N1 "swine flu" virus were equivalent to the manif...

Awareness and practices regarding zoonotic influenza prevention in Romanian swine workers
ConclusionsDespite awareness and concern regarding zoonotic influenza, Romanian swine workers report low rates of influenza vaccine or respiratory protection. As part of global pandemic influenza preparedness, enhanced prevention programs for swine workers should address such gaps.

Health System Contact and Awareness of Zoonotic Diseases: Can it Serve as One Health Entry Point in the Urban Community of Ahmedabad, India?
Yale J Biol Med. 2021 Jun 30;94(2):259-269. eCollection 2021 Jun.ABSTRACTOne Health (OH) is emphasized globally to tackle the (re)emerging issues at the human-animal-ecosystem interface. However, the low awareness about zoonoses remain a challenge in global south, thus this study documented the health system contact and its effect on the awareness level of zoonoses in the urban community of Ahmedabad, India. A community-based household survey was conducted between October 2018 and July 2019. A total of 460 households (HHs) were surveyed from two zones and 23 wards of the city through cluster sampling. A structured, pilot-t...
