Recently, Beijing has experienced significant drops in temperature. Combined with dry air and large temperature differences between day and night, the risk of contracting infectious respiratory diseases such as influenza has increased. The Beijing Center for Disease Prevention and Control (Beijing CDC) reminds you to stay informed of flu prevention and take sensible measures to protect your own health and that of your family.

What is influenza?

Influenza, commonly known as the flu, is an acute respiratory infection caused by influenza viruses. Typical symptoms include persistent high fever, headache, body aches, sore throat, fatigue, and listlessness, often accompanied by coughing.

The flu mainly spreads through droplets released when infected individuals sneeze, cough, or talk. It can also be transmitted by touching the mouth, nose, or eyes after direct or indirect contact with objects contaminated by an influenza virus.

How to prevent influenza during the flu season?

1. Get vaccinated

The flu vaccine is the most effective way to prevent infection and reduce the risk of severe complications. It is recommended to get vaccinated between September and November each year before the winter flu season.
Priority groups for annual vaccination include:

(1) Adults aged 60 years and above

(2) Children aged between 6 months and 5 years

(3) Pregnant women

(4) Household members and caregivers of infants aged under 6 months

(5) People with chronic health conditions

(6) Healthcare workers

Those who have not yet been vaccinated should, if eligible, get the flu vaccine as soon as possible.

2. Practice good daily hygiene

(1) Wash hands frequently with soap and running water, or use an alcohol-based sanitizer.

(2) Wear a mask in crowded or poorly ventilated areas during the flu season.

(3) Practice good respiratory hygiene — cover your mouth and nose with a tissue or your elbow when coughing or sneezing.

(4) Avoid crowded or enclosed spaces. If necessary, wear a mask to reduce the risk of infection.

(5) Keep indoor air fresh by opening windows regularly for ventilation.

(6) Keep a safe distance of at least one meter from flu patients. Avoid touching their personal items such as dishes, towels, or clothing. If contact is unavoidable, disinfect the items beforehand.

(7) Strengthen immunity through a balanced diet, moderate exercise, and adequate rest.

What to do if you get the flu?

If you develop flu symptoms (such as sudden fever or body aches), rest at home or seek prompt medical attention depending on the severity of your condition. During home recovery, avoid close contact with others, keep your living environment clean and well-ventilated, and disinfect frequently touched items.
