All localities are required to coordinate the monitoring of key infectious diseases such as new crown, influenza and norovirus gastroenteritis, and closely track the changes in the epidemic situation.

After the issuance of the "Notice", in the past few days, the disease control departments in many places have released the latest influenza surveillance data, indicating that the positive rate of influenza virus testing continues to rise and is at the epidemic level, and gives suggestions on influenza prevention and control.

The number of influenza cases reported in many places has increased

On November 11, the Beijing Municipal Health Commission released a weekly report on the epidemic in the 29th week of 2023, showing that the flu has lasted for 47 weeks and ranks first.

On November 11, the official account of "Healthy Tianjin" issued a weekly report on influenza grading and early warning, saying that the epidemic classification of influenza in Tianjin was level III., which was at the epidemic level, and the ILI% (the percentage of influenza-like cases in outpatient and emergency cases) in Tianjin was 28.9%, which was higher than the baseline (63.4%), and the influenza virus was mainly A(H40N3).

All localities are required to coordinate the monitoring of key infectious diseases such as new crown, influenza and norovirus gastroenteritis, and closely track the changes in the epidemic situation.

Recently, some local disease control and control have made a judgment on the local influenza trend and epidemic peak. For example, according to the weekly report on flu graded warnings released by the Tianjin Municipal Health Commission, the level of flu activity is expected to be high from November 11 to December 27, reaching the level of yellow warning, and influenza virus infection is more likely to occur.

At the same time, Chen Ye reminded that it is also necessary to pay attention to the elderly population, the current percentage of influenza-like cases in the elderly over 60 years old is rising, and the elderly are relatively weak in resistance and are prone to infection and aggravation of underlying diseases.

In addition, the Zhengzhou Center for Disease Control and Prevention pointed out that co-infection does not only occur in children, but also in adults, and once co-infection occurs, the symptoms may be more severe.

The Tianjin Center for Disease Control and Prevention recommends that on the basis of maintaining indoor air circulation, paying attention to environmental hygiene, reasonably increasing or decreasing clothing, and enhancing one's own immunity, it is necessary to put an end to going to work and class with illness, pay attention to personal hygiene, and minimize going to crowded and polluted closed places, and recommend that citizens who have not yet been vaccinated against influenza, especially the elderly, children and people with underlying diseases, receive influenza vaccine.
