Avian flu virus can last indefinitely at a temperature dozens of degrees below freezing, as is found in the northernmost areas that migratory birds frequent. [citation needed] Heat kills H5N1 (i.e. inactivates the virus). Influenza A viruses can survive: Over 30 days at 0 °C (32.0 °F) (over one month at freezing temperature)
Flu A can infect people and animals, while flu B is mostly a human virus. There are also 130 different subtype combinations of flu A, while flu B has just two lineages (B/Yamagata and B/Victoria ...
In November 2021 the CDC announced that several frozen vials labeled "Smallpox" were discovered in a freezer in a Merck & Co. vaccine research facility at Montgomery County, Pennsylvania.

The CDC says in guidance on cleaning after someone has monkeypox that the virus can live on surfaces like sheets for up to 15 days. But the organization also notes that orthopoxviruses like ...
Temperature has the highest effect on virus's survival in water since lower temperatures are the key to longer virus survival. For instance, an article published in 2018 noted that it takes one year for certain viruses including poliovirus and echovirus to decrease by a 5log unit at a temperature of 4 ° C, while it takes only a week to obtain ...
If a person infected with the Ebola virus rides the subway and has a body fluid (such as mucus from sneezing) on his or her hand, and then touches the railing on a subway, the virus can live up to ...
However, the freezer compartment of this type is not recommended to store vaccines, and vaccines should be stored centrally inside the refrigerator. Many combination units cool the refrigerator using air from the freezer, resulting in different temperature zones inside the fridge. [ 7 ]
