If you're wondering when you might get the flu, a new study indicates you should keep an eye on your local weather report.
According to a research published in the Journal of Clinical Virology, if you keep your eye on the weather and watch for the first major dip in the temperature, you can essentially mark your calendar in prediction for an outbreak the flu.
To figure out how the weather and flu outbreak may be connected, researchers analyzed statistics of 20,000 people in an area over three seasons. The number of people who caught the flu was then compared with local weather data.
After each season, the team noticed one consistent finding: The first really cold period with low outdoor temperatures and low humidity (湿度) was always followed by a week of a mass influenza outbreak.
The researchers say that aerosol particles (气溶胶粒子) containing virus and liquid are more able to spread in cold and dry weather. So, in theory, if you sneeze or cough and the surrounding air is very dry, the air will absorb the moisture and the particles containing the virus keep spreading through the air for a longer period of time.
Luckily there are ways to keep off the illness regardless of the weather. Washing your hands, coughing into the crook (弯曲) of your arm and getting vaccine (疫苗) are the best ways to prevent the flu from spreading. People over the age of 65, pregnant women and young children are at the highest risk of developing complications (并发症) related to the virus, according to the CDC.
