流感 Prevent flu

Influenza (referred to as flu)

An acute respiratory infection caused by influenza virus. Influenza has the characteristics of short incubation period, strong contagion, and rapid spread. Collective units such as schools and childcare institutions are prone to outbreaks.

The temperature in March is still low, and it is cold and warm, and the temperature difference is large. These are all suitable for the survival of influenza viruses, so we must still pay attention to prevent influenza.

Prevention of chicken pox


Onset symptoms

The incubation period of chickenpox is usually 1 to 2 weeks. At first, symptoms such as fever and general discomfort will appear. The first symptom after a child's illness is a rash.


Chickenpox has a characteristic rash. First, there is a characteristic red spotted rash, which later turns into pimples. It develops into a blister with intense itching. The rash started to dry and crust after 3 or 4 days. At the same site, rashes, blisters, and scabs may coexist.


Children with systemic symptoms and rashes are mild, adults and infants are more ill, rashes are more dense, and they are prone to varicella pneumonia. Those with low immune function are prone to form disseminated chickenpox.


Varicella is a self-limiting disease. If there are no complications, it will heal in about 10 days and the prognosis is generally good. After infection, permanent immunity to varicella virus can be obtained.



Vaccination is the most effective way to prevent and control chickenpox. Numerous epidemiological studies have confirmed the safety and immune effect of chickenpox vaccine.

Varicella vaccine is a second-class vaccine in Zhejiang Province and is voluntarily given at its own expense.

Inoculation object:

(I) Recommended objects: Children and adolescents over 1 year old.

(2) Other recommended targets: key populations such as medical staff, school teachers, etc .; high-risk populations such as susceptible persons in households who are in close contact with chickenpox patients (age <40 years, no history of chickenpox)

The vaccine should be given throughout the year, but it is not recommended for children who have been infected with the chickenpox-zoster virus.
