More than 99% of cases are influenza A! Urgent reminder →

Recently, influenza has been prevalent. According to the latest data from the China Center for Disease Control and Prevention, the influenza virus positive rate continues to rise, of which more than 99% are influenza A. Disease control centers in many parts of the country have urgently reminded people to take good personal protection and pay attention to preventing respiratory and intestinal infectious diseases.

The national influenza virus positive rate is rising rapidly

According to data released by the Chinese Center for Disease Control and Prevention:

The main positive pathogens detected in outpatient and emergency departments of sentinel hospitals were influenza virus, human metapneumovirus, and rhinovirus; the main positive pathogens detected in hospitalized severe acute respiratory infection cases were influenza virus, Mycoplasma pneumoniae, and human metapneumovirus.

It can be seen that influenza is one of the most important pathogens in both outpatient and emergency cases and serious hospitalized cases.

What is influenza?

Influenza A, or "H1N1", is an acute respiratory infectious disease caused by influenza A virus. Influenza viruses are divided into four types: A, B, C, and D. Among them, influenza A is the most contagious and most likely to mutate. Almost every influenza pandemic is caused by influenza A virus.

The main symptoms of influenza A infection are sudden high fever, often with respiratory symptoms such as cough, sore throat, nasal congestion, runny nose, accompanied by headache, muscle aches and other general discomfort, and some patients will experience gastrointestinal discomfort.

What is the difference between influenza A and the common cold?

▲ Common cold

It is caused by multiple pathogens such as rhinovirus, has weak infectiousness, and has no obvious seasonal characteristics. Symptoms include nasal congestion, runny nose, sneezing, coughing, etc., usually without fever or only low fever, and no systemic symptoms. It can heal itself in 5-7 days, and complications rarely occur.

▲H1N1

In contrast, influenza A is highly contagious, easily spreads across a large area, and has obvious seasonal characteristics. Patients experience symptoms such as high fever, headache, fatigue, and body muscle aches.

Influenza A has a certain degree of self-limitation, but it is prone to cause other complications, including pneumonia, otitis media, myocarditis, meningitis and other serious complications.

What is the difference between mabaloxavir and oseltamivir?

Because of its effectiveness against influenza A and B viruses, many people regard oseltamivir as a "miracle drug" against influenza.

▲What is the main function of oseltamivir? Can I take oseltamivir on my own?

Oseltamivir is a drug with antiviral activity against influenza A and B. It can inhibit the release of viruses from infected cells and reduce the spread of viruses. Experts point out that oseltamivir is ineffective against other types of cold viruses. If you have cold symptoms, you should seek medical attention in time and take medicine as soon as possible after diagnosis.

Oseltamivir has different dosage forms, including capsules, granules and suspensions, to suit people of different age groups. Only suspensions are available for infants under one year old. Oseltamivir is a prescription drug. When used to prevent or treat influenza A, it must be used under the guidance of a doctor or pharmacist. Self-administration is not recommended.

▲What is the difference between Mabaloxavir and Oseltamivir?

As the number of influenza infections increases, the sales of anti-influenza drugs have continued to grow recently, especially a drug called "Mabaloxavir", which has been sought after by everyone.
According to doctors, the mechanism of action of Mabaloxavir is different from that of Oseltamivir.

Mabaloxavir inhibits the replication of influenza virus, preventing the virus from entering the body; oseltamivir inhibits the release of the virus from infected cells, reducing the spread of the virus.
The elimination half-life of mabaloxavir after a single dose is approximately 79 hours; the half-life of oseltamivir blood concentration decreases is generally 6 to 10 hours.

Mabaloxavir only needs to be given once throughout the entire course of the disease; oseltamivir needs to be taken twice a day for five consecutive days.

Baloxavir is currently only approved for use in children over 5 years old and weighing more than 20 kg and adults; oseltamivir capsules and granules can be used for children over 1 year old and adults, and the dry suspension is suitable for an even younger age. For young children, the dosage is calculated based on their weight.

Doctors remind that infants and young children should give priority to seeking medical treatment in a timely manner after being infected and take medication under the guidance of a doctor. Medication safety should also be a priority for pregnant and lactating patients.

What should I do if there is a influenza A patient in my family?

Patients are advised to rest at home. Try to live in a single room, keep the room ventilated, and reduce the chance of contact with co-residents.

Patients need to pay attention to personal hygiene, maintain good respiratory hygiene habits, and cover their mouths and noses with tissues or towels when coughing or sneezing.

Closely monitor the health status of the patient and family members. If the patient or other family members have persistent high fever, accompanied by severe cough, breathing difficulties, mental changes, severe vomiting and diarrhea, etc., they should seek medical attention in time.

Whenever possible, the patient should be cared for by a fixed family member who is not at high risk of influenza, and a mask should be worn when in close contact with the patient.

The key to preventing influenza A is to do these things

▲Do a good job of personal protection and environmental hygiene

Pay attention to maintaining good hygiene habits such as hand hygiene and coughing etiquette on a daily basis.

During the influenza season, try to avoid going to crowded places and avoid contact with people with respiratory symptoms.

Clean and ventilate your residence regularly, and clean and disinfect key areas such as door handles and handrails regularly.

When going to public places or going to the hospital for treatment, patients and their caregivers must wear masks to avoid cross infection.

Especially the elderly should avoid going to poorly ventilated public places unless necessary, and develop the habit of wearing masks when going out.

▲Pay attention to daily nutrition and maintain a healthy lifestyle

Eat regularly and get enough nutrition.

Get enough sleep and combine work and rest.

Keep exercising to improve your physical fitness.

Be calm, optimistic and positive.

▲Get a flu shot as soon as possible

Flu vaccination is one of the main measures to prevent and control influenza. Vaccinating people with flu vaccines before the flu season can reduce the chance of the vaccine recipients contracting the flu or alleviate the symptoms of the flu.
