Swine influenza

Swine influenza, or swine flu, is a respiratory illness caused by influenza viruses that primarily affect pigs. It can occasionally infect humans, leading to symptoms similar to regular flu, such as fever, cough, and body aches. People can contract swine flu through direct contact with infected pigs or by being in close proximity to infected individuals. While most cases are mild, some can be severe, particularly in vulnerable populations. Vaccines exist to protect both pigs and humans against this virus, emphasizing the importance of vaccination and hygiene to prevent outbreaks.
