1. Do you use cough medicine when your baby coughs?
Rumor content:In autumn and winter, children have a high incidence of respiratory tract infections, and some parents see that their babies are coughing, so they immediately buy cough medicines for their babies.
Truth Interpretation:Not recommended,You should strictly follow your doctor's instructions and prescribe the right medicine. Cough is a common respiratory symptom in children, children's bronchial mucosa is delicate, the ability to resist external bacterial infections is poor, and it is easy to develop respiratory tract inflammation and cough. This is a protective reflex of the human body, and the germs and sputum in the respiratory tract can be expelled from the body by coughing, which plays a role in cleaning the respiratory tract and keeping it open.
In fact, in the early stage of the baby's phlegm cough, early expectoration can fundamentally solve the cough. If you don't get expectorant and stop coughing first, it seems that the baby's cough is temporarily relieved, in factThe phlegm does not decrease at all, but gives the pathogen time to buffer, forming a new infection and even progressing to pneumonia.
In addition,Not all cough suppressants are suitable for children. Cough suppressants containing codeine and dextromethorphan have a central antitussive effect, but excessive use of these two ingredients carries a risk of respiratory depression, and codeine is addictive and can produce strong dependence. Therefore,Parents are advised to consult a doctor before giving cough medicine to their children, and the doctor will diagnose the medication before taking it.

2. The humidifier will cause "humidifier pneumonia", and the humidifier can not be used?
Rumor content:Long-term use of humidifiers will lead to the breeding of germs, bringing hidden health hazards to the human body, resulting in "humidifier pneumonia".
Truth Interpretation:Inaccurate. Proper use of a humidifier does not cause pneumonia. If a humidifier is filled with unclean water, germs can spread into the air by the humidifier, and adding disinfectant-containing water directly to the humidifier can irritate the person's respiratory system.
In addition, many ultrasonic humidifier nebulizers are prone to accumulation of dirt there, and if they are not cleaned and disinfected regularly, it may also lead to the growth of germs, and the germ-carrying water mist generated after humidification will be inhaled by us, which is more likely to cause diseases.
So the right way to do it is,Use clean water and wash your humidifier regularly.

Do you have to take antiviral drugs if you have influenza A?
Rumor content:Influenza A is an acute respiratory infection caused by influenza A virus infection, and the number of people getting influenza A has gradually increased since the beginning of winter. Many people believe that if you have influenza A, you need to take antiviral drugs as soon as possible.
Truth Interpretation:Not necessarily, antiviral drugs are mostly prescription drugs, and there are conditions for use, so it is recommended to use them under the guidance of a doctor.
*Common antiviral drugs for influenza A include oseltamivir, peramivir, mabaloxavir, etc.
Severely ill patients and high-risk groups such as pregnant women, immunosuppressed people, and people with serious underlying diseases (chronic respiratory diseases, kidney diseases, cardiovascular diseases, the elderly, etc.) should seek medical attention as soon as possible and use antiviral drugs under the guidance of doctors。People with mild disease and no of these high-risk factors should weigh the pros and cons and use antiviral drugs as appropriate.

When you have a cold that is about to recover, it is most contagious?
Rumor content:When the cold is about to heal, the virus needs to multiply and is the most contagious, and the isolation should be strengthened from this time until it is completely **.
Truth Interpretation:Mistake. The most contagious time for colds is the first 2-3 days after the onset of symptoms.
A cold usually refers to an illness caused by an invasion of the respiratory tract by a pathogen, and the incubation period is usually 2 to 4 days. When a cold presents symptoms such as chills, fever, headache, sneezing, etc., the pathogen has multiplied in large numbers in the respiratory tract. EspeciallyIn the first 2 to 3 days after the onset of symptoms of a cold, the pathogen is most active, most numerous, and more contagious. As the disease improves, the contagiousness gradually decreases.
The reason for the misconception that "when you have a cold is about to recover, it is most contagious" isThe incubation period of a cold leads to a mismatch in the timing of the onset of the cold between the infected and the infected.

Sleeping with wet hair causes cancer?
Rumor content:Sleep with wet hair often beware of cancer, because sleeping with wet hair can easily breed Malassezia on the scalp, and studies have proved that the migration of Malassezia from the intestine to the pancreas may induce and promote pancreatic ductal adenocarcinoma.
Truth Interpretation:Mistake. Malassezia is a fungus that mainly exists on the surface, mainly on the scalp, and in some cases such as low body immunity, its proliferation and reproduction may cause two common diseasesTinea versicolor and Malassezia folliculitis, both of which are mild in themselves and generally do not cause serious consequences. Systemic ** infection caused by Malassezia is very rare.
Malassezia does prefer hot and humid environments, but washing your hair itself reduces the number of Malassezia, and secondly, depending on the length and volume of your hair, it doesn't take long for wet hair to dry out enough for it to return to its pre-wash amount, so don't worry too much.

After a high-risk behavior, a negative test result means that you are not infected with HIV?
Rumor content:There are comments on the Internet that after high-risk behaviors, you need to go to the hospital for testing immediately, and if the result is negative, it means that you are not infected with HIV.
Truth Interpretation:
Mistake. There is a window period after HIV infection. When the virus first infects the body, the amount of HIV virus amplification is still very small, and it is difficult to detect HIV virus antibodies, antigens, nucleic acids and other markers of infection. At this time, although the test result is negative, the body is actually infected with the HIV virus, and then as the virus increases, it will still get sick.
