The swine influenza virus is common throughout pig populations worldwide. Transmission of the virus from pigs to humans is rare and does not always lead to human illness, often resulting only in the production of antibodies in the blood. If transmission causes human illness, it is called a zoonotic swine flu. People with regular exposure to ...
The COVID-19 virus has not been detected in drinking water. [82] Conventional water treatment (filtration and disinfection) inactivates or removes the virus. [82] COVID-19 virus RNA is found in untreated wastewater, [82] [22] [83] [a] but there is no evidence of COVID-19 transmission through exposure to untreated wastewater or sewerage systems ...
Transmission and life-cycle of SARS-CoV-2 causing COVID-19. Coronaviruses vary significantly in risk factor. Some can kill more than 30% of those infected, such as MERS-CoV, and some are relatively harmless, such as the common cold. [49] Coronaviruses can cause colds with major symptoms, such as fever, and a sore throat from swollen adenoids. [91]
It was caused by a novel H1N1 strain that was a reassortment of human, swine, and avian influenza viruses. [20] [4] The 2009 pandemic had the effect of replacing prior H1N1 strains in circulation with the novel strain but not any other influenza viruses. Consequently, H1N1, H3N2, and both influenza B virus lineages have been in circulation in ...
Pigs are mixing bowls for bird flu and human flu viruses, increasing the risk of mutations that help H5N1 spread to humans. It's still not inevitable.
Influenza viruses: You’re likely familiar with the seasonal flu, but in the last century there have also been four influenza pandemics: the infamous Spanish Flu pandemic in 1918, the H2N2 flu ...
The Centers for Disease Control and Prevention (CDC) identified the first two A/09(H1N1) swine flu cases in California on April 17, 2009, via the Border Infectious Disease Program, [135] for a San Diego County child, and a naval research facility studying a special diagnostic test, where influenza sample from the child from Imperial County was tested.

The 2009 swine flu pandemic, caused by the H1N1/swine flu/influenza virus and declared by the World Health Organization (WHO) from June 2009 to August 2010, was the third recent flu pandemic involving the H1N1 virus (the first being the 1918–1920 Spanish flu pandemic and the second being the 1977 Russian flu).
