Disease/Condition Glossary
Influenza: Influenza or flu is produced by a virus that causes respiratory disease. It is highly infectious and quickly spreads through the droplets or sneezes and coughs of an infected person. Adults can start circulating the virus two days before the symptoms start showing up. They can spread it for up to 7 days from the day they become sick. This means you can stop spreading the influenza virus route before figuring out that you are ill. Influenza or flu is produced by a virus that causes respiratory disease. Symptoms of influenza include a blocked or runny nose, sore throat, cough, and headache. Other symptoms include high temperature, shivers, cold sweat, nausea, diarrhoea, and vomiting. In most cases, influenza is not severe, while, in some cases, flu can cause severe complications. This condition is primarily seen in older people, young children, and people with long-lasting diseases that can compromise their immune systems.

Yes, Inactivated Influenza Vaccine is used to prevent swine flu symptoms. Inactivated Influenza Vaccine contains a very small amount of the flu virus which is introduced in our body to stimulate the production of antibodies (chemicals that attack that specific virus). This promotes the development of immunity against the virus infection in the future.
