SWINE flu (H1N1) is highly contagious and is caused by a new strain of influenza virus. In recent weeks Swine flu has wrecked havoc across the country.

H1N1 flu signs and symptoms in humans are similar to those of other flu strains like fever, cough, sore throat, running nose, body aches, headaches and fatigue. Swine flu patients also report diarrhoea and vomiting. This is thought to be one of the ways it differs from seasonal flu but the laboratory test is the only way to confirm.

The spread of influenza can only be prevented with the help of public awareness. You can help prevent the spread of germs by covering your nose and mouth with a tissue when you cough or sneeze. Washing your hands thoroughly and frequently, especially after you cough or sneeze. Try to avoid close contact with sick people. Stay home from work or school if you are sick. The best way to prevent yourself from swine flu is to get the flu vaccination every year.

Some people are at higher risk. These include infants and children. Adult over age 65, pregnant women and people with certain health conditions or a weakened immune system.

Swine flu can lead to more serious problems, including pneumonia, a lung infection, and other breathing problems. This can be serious, even life-threatening especially for people with weak immune systems or people with chronic diseases. Condition such as asthma, diabetes or congestive heart failure may also be aggravated by swine flu.
