Biosafety Level 2 ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services.
Is H1N1 still a risk?
The global H1N1 pandemic was declared over in August 2010. However, H1N1 is still circulating. You can prevent catching H1N1 by getting an annual flu shot. In addition, wash your hands frequently or use hand sanitizer and avoid indoor crowds during outbreaks of the flu.

The designation “H1N1” indicates unique traits, which exhibit characteristics that identify the virus to the immune system and allows for attachment and replication of the virus. The “H” (hemagglutinin) and the “N” (neuraminidases) are both proteins that are found on the outer shell or envelope of the virus.
Is PR8 A H1N1?
PR8 is a mouse-adapted H1N1 influenza virus that is known to cause severe infection in mice. In contrast, x31 is an H3N2 influenza virus that causes mild to moderate illness in mice, despite containing the six internal genes of PR8.

Does H1N1 cross the placenta during pregnancy?
In most cases, it appear that the influenza virus does not cross the placenta to infect the baby, although this has occurred in some cases, including one pregnant woman who had 2009 H1N1 near the end of her pregnancy whose newborn was infected with 2009 H1N1.
