Is 48 hours of flu onset a "golden self-help period"?

Why is it that 48 hours of flu onset is a golden self-help period? Cao Bin, vice president of China-Japan Friendship Hospital and director of the Department of Respiratory and Critical Care Medicine, introduced in an interview with CCTV in January, 2024 that 48 hours after the onset of influenza, we call it "the golden 48 hours of self-help". If effective antiviral drugs are not used within the "golden 48 hours", it is possible that the flu will develop into pneumonia, white lung and other severe degrees, especially for people with severe and high-risk influenza. ①

First, children: the antiviral effect is the best within 48 hours.

Chen Xing, chief physician of Pediatrics Department of Provincial Hospital affiliated to Shandong First Medical University, introduced in an interview with Qilu Evening News on January 10th that children infected with influenza mainly show fever, headache and general malaise, and their body temperature can reach 39-40℃, and the fever degree of children is usually higher than that of adults. Once the flu is diagnosed or highly suspected, active antiviral treatment should be taken. The best effect can be achieved by antiviral treatment within 48 hours after symptoms appear, but even if it exceeds 48 hours, antiviral drugs can also benefit. Therefore, for children, no matter how many days the flu symptoms appear, if the condition has not improved, antiviral drug treatment should be started as soon as possible after suspicion or diagnosis. ②

Second, adults: taking medicine within 48 hours can shorten the course of disease.

For healthy adults, 48 hours after flu symptoms appear is considered as the best treatment time. During this time, it is very effective to start taking antiviral drugs as soon as possible. Early use of antiviral drugs can inhibit the replication and spread of the virus, help shorten the duration of the flu, and usually shorten the course of the disease by about one to two days. Most importantly, it is also helpful in preventing influenza complications and severe cases.

Third, high-risk groups: 48 hours of medication to reduce severe illness.

According to Dr. Cao Bin, there are three types of people who are infected with influenza, and the risk of developing into severe illness is higher than others:

1. People over 65 years old

2. People with basic diseases

3. People receiving immunosuppressant treatment

In addition, if the body temperature is above 39°C for 3 days and you have difficulty breathing, you should seek medical attention in time, and the possibility of self-healing is small. High-risk groups using effective antiviral drugs within the "golden 48 hours" can avoid developing pneumonia, severe illness and white lung as much as possible.

Do three things well after catching the flu!

1. Timely detection to find out the pathogen.

Dr. Cao Bin suggested that you can prepare a flu self-test reagent in advance at home, which is not expensive. When we have flu symptoms, we can detect them in time and determine whether it is the flu at the first time.

In addition to self-test reagents, you can also go to the hospital for testing in time. Hu Yang, deputy chief physician of the Department of Respiratory and Critical Care Medicine of pulmonary hospital, introduced in Chang Xiao’s health article on January 29th that the progress of science and technology has greatly shortened the time for clinical detection, and the detection time of influenza A and influenza B can be basically completed in one or two hours in the outpatient department of a large 3A hospital, so that we can find out which pathogen caused the cold, avoid treating it in a muddle as before, and make the treatment more accurate. ③

2. Antiviral treatment within 48 hours.

Dr. Cao Bin said that you can’t use antibiotics indiscriminately when you have the flu. The flu is a virus, and antibiotics have inhibitory or killing effects on bacteria. It is useless for viruses; In addition, infusion can’t treat the flu, infusion mainly supplements water, and infusion can’t treat the flu.

The correct way is to take antiviral drugs, such as oseltamivir or mabaloxavir, within 48 hours after the diagnosis of influenza. Mabaloxavir acts on the stage of viral RNA replication, which is earlier than that of traditional drugs, so it has stronger ability to remove viruses, and it is very convenient to take it, and it only needs to be taken once in the whole course. ②

Have a good rest, don’t stay up late and get tired

Pay attention to rest after the flu, and never stay up late! It is recommended to drink plenty of water and rest during the flu to ensure nutrition. Avoid strenuous exercise, so as not to increase the risk of cardiovascular accidents.
