H1N1 News and Research

RSS

Novel influenza A (H1N1) is a new flu virus of swine origin that was first detected in Mexico and the United States in March and April, 2009. The first novel H1N1 patient in the United States was confirmed by laboratory testing at CDC on April 15, 2009. The second patient was confirmed on April 17, 2009. It was quickly determined that the virus was spreading from person-to-person. On April 22, CDC activated its Emergency Operations Center to better coordinate the public health response. On April 26, 2009, the United States Government declared a public health emergency.

It’s thought that novel influenza A (H1N1) flu spreads in the same way that regular seasonal influenza viruses spread; mainly through the coughs and sneezes of people who are sick with the virus.

Human-swine influenza A transmission and evolution of variants

A new study of the strain of influenza A responsible for the 2009 H1N1 pandemic-;pdm09-;shows that the virus has passed from humans to swine about 370 times since 2009, and subsequent circulation in swine has resulted in the evolution of pdm09 variants that then jumped from swine to humans.

How does chronic HBV infection affect flu and COVID-19 vaccine responses?

The influenza season marks the beginning of a time of illness, sometimes serious or even fatal, in much of the world. For this reason, flu shots are recommended, especially for individuals with underlying diseases such as chronic hepatitis B (CHB) infection, since they are at higher risk for adverse outcomes.
