Protecting against spread of swine flu.

• Position: Pandemics

The main route of transmission of the influenza A (H1N1) virus seems to be similar to seasonal influenza, via droplets that are expelled by speaking, sneezing, or coughing, cautions the World Health Organization, Geneva, Switzerland.

An individual can prevent getting infected by avoiding close contact with people who show influenza-like symptoms (trying to maintain a distance of about three feet if possible) and taking the following measures: avoid touching your mouth and nose; clean hands thoroughly with soap and water, or cleanse them with an alcohol-based hand rub on a regular basis (especially if touching the mouth and nose, or surfaces that are potentially contaminated); avoid close contact with people who might be ill; if possible, reduce the time spent in crowded settings; improve airflow in your living space by opening windows; and practice good health habits, including get ling adequate sleep, eating nutritious food, and keeping physically active.
