This document summarizes information about swine flu. It defines swine flu as a respiratory disease of pigs caused by influenza viruses. While humans do not normally get swine flu, they can contract it from close contact with pigs. Symptoms in humans are similar to seasonal flu and include fever, coughing, and sore throat. The current outbreak has caused over 80 deaths in Mexico and spread to other countries. Experts are monitoring the situation closely due to the potential for a pandemic if the virus spreads widely and affects a large portion of the population. People are advised to follow good hygiene practices to reduce transmission.
