Influenza A or H1N1, also known as swine flu, is a respiratory disease that can affect both pigs and humans. It’s a subtype of the influenza A virus that causes infections in the upper and sometimes lower respiratory tract. The virus spreads through the air by coughing, sneezing, breathing, and talking, and can also enter the body via contaminated surfaces. The virus is contagious from about a day before symptoms appear until about four days after they start. Children and people with weakened immune systems may be able to spread the virus for a slightly longer period of time.

The Central government has been keeping a strict vigil on zoonotic diseases across India. Zoonoses are infectious diseases that can transfer between animals and humans, including rabies, anthrax, influenza (H1N1 and H5N1), Nipah, COVID-19, brucellosis, and tuberculosis. These diseases are caused by various pathogens, including bacteria, viruses, parasites, and fungi.
A senior Health Ministry official noted that the prevention and control of zoonotic diseases is achieved by vaccination, good hygiene and animal husbandry practices, and vector control.
