H3N2 is a strain of influenza virus that can spread through respiratory droplets. To reduce the risk of contracting H3N2, individuals should take steps to maintain good indoor air quality. This can be achieved by using air quality control measures such as air filters, humidifiers, and dehumidifiers.

Proper ventilation is also important in preventing the spread of the virus. Individuals should ensure that the air in their living and workspaces is regularly exchanged with fresh air from outside.

Moisture control is another important factor in maintaining good indoor air quality. High humidity levels can create an environment that is conducive to the growth and spread of viruses, including H3N2. A dehumidifier can help reduce humidity levels, while a humidifier can help add moisture to the air if it is too dry.

If an individual believes they have been exposed to H3N2, they should monitor themselves for symptoms such as fever, cough, and body aches. If symptoms develop, they should seek medical attention and inform their healthcare provider of their potential exposure to the virus.

Current vaccines against H3N2 are generally effective, but their effectiveness can vary from season to season due to changes in the virus.
