Though the H1N1 strain of flu currently appears to pose only a mild threat, we can still use it as an opportunity to learn about effective strategies for preventing the spread of a viral pandemic. Although the H1N1 virus represents a new viral mutation, it can be prevented in the same ways as other influenza viruses.

The efficacy of any prevention strategy depends upon having accurate knowledge about the threat at hand. Although many of the prevention tactics are the same despite the strain of virus, the degree to which they should be applied depends upon the severity of the threat. Being aware of factors such as the most heavily impacted areas, symptoms of the virus, ease of transmission, and special advisories by experts is vital for taking an appropriate course of preventative action.

Viruses are spread primarily by respiratory droplets being expelled and then inhaled into the upper airways and also by introduction through the eyes, nose, throat or any openings in the skin after touching a contaminated surface. The following strategies, in order of importance, are necessary for preventing the spread of an influenza outbreak.

1. Practice Social Distancing/Avoidance

Using social distancing is the most effective way of preventing the spread of the H1N1 virus. This involves increasing spacing and reducing physical contact between people while conversing, walking etc. Because the H1N1 virus can take days to present symptoms, it is necessary to act as if anyone could be a potential carrier. Take extra caution around anyone who presents obvious flu like symptoms, especially coughing or sneezing. Coughing and sneezing usually spread the virus liberally within a 3 foot radius, though droplets have been known to travel much further, depending on air currents and conditions. Caution should be taken near any surfaces that are frequently touched as the virus can live up to 24 hours on non-porous surfaces. Use common sense and avoid touching handles, buttons, and any other frequently handled items. If possible use your shirt sleeve or a cloth as a barrier (e.g. open doors with your elbow) to help limit exposure to yourself and others. Depending on the risk, social distancing should also incorporate avoidance as well. Avoid crowded places (e.g. malls) where close contact is unavoidable or places (e.g. hospitals) where people are more likely to carry the infection.
