What is “A stream”?

Director Wang Jin introduced that influenza is an acute respiratory infectious disease caused by influenza virus. Influenza patients and asymptomatic infected persons are the main sources of infection for seasonal influenza. Influenza is mainly transmitted by droplets, and can also be transmitted through direct or indirect contact with mucous membranes such as the mouth, nasal cavity, and eyes. Children usually have a sudden onset of the disease, the main symptom is fever, the body temperature can reach 39-40 ℃, often accompanied by cough, sore throat, runny nose/nasal congestion, muscle aches all over the body, etc. In addition, nausea, vomiting, diarrhea and other symptoms may also occur. At present, the results of influenza surveillance by disease control agencies in various places show that the current level of influenza virus activity in my country has increased, and influenza A is the main one. Patients and those with latent infection are the main source of infection. Patients can excrete the virus from secretions such as nasal mucus, saliva, and sputum within 5 days after the onset of the disease.

Director Wang Jin said that oseltamivir is effective against both influenza A and B viruses, but not against viruses that cause the common cold. Oseltamivir can prevent influenza virus replication and pathogenicity in the human body, relieve influenza symptoms, and reduce the spread of influenza A or B viruses. Therefore, oseltamivir can be used for the treatment and prevention of influenza A and B, and can be taken under the guidance of a doctor. Children who take oseltamivir usually choose granules (15mg/bag) for convenience. The Chinese drug instructions clearly state: for adults and children aged 1 and over for the treatment of influenza A and B (patients should use it within 48 hours of the first onset of symptoms); for adults and adolescents aged 13 and over Prevention of Influenza A and B.

The following weight-dose schedule is recommended for children over 1 year of age

The incubation period of norovirus infection is usually 24 to 48 hours. The most common symptoms are diarrhea and vomiting, followed by nausea and abdominal pain, but other symptoms such as mild fever, headache, chills and body aches can also occur, and dehydration can occur in severe cases.
