3 Misunderstandings Against Influenza
Both days of the strong cold air south, the hospital clinics were full of people, most of them came to see a cold.
Professor Wang Tong, Department of Emergency Medicine, Sun Yat-sen Memorial Hospital, Sun Yat-sen University, said that spring is a season of frequent influenza, and the elderly, children, pregnant women and chronic patients are easily recruited.
To prevent colds, in addition to washing your hands frequently, opening windows, drinking plenty of water, and not staying up late, some people have their own common tricks. Are these tricks reliable?
Myth 1 Some people use medical disinfectants. Some people use hospital alcohol, peracetic acid, soda, etc. to disinfect homes to prevent influenza. Wang Tong said: “In general, even in the flu season, homes should not be over-sterilized.Patients can wipe with an appropriate amount of chlorine disinfectant, and then wipe with water.
“This is because alcohol is a medium-effect disinfectant, commonly used at a concentration of 75%. It can kill most bacteria, fungi, and viruses, but it cannot kill bacterial spores and some hydrophilic viruses such as hepatitis A virus andPoliovirus.
As soon as the wind blows, the dust falls, and the place where the alcohol has been wiped gets bacterial again.
However, peroxyacetic acid and soda water are very acidic, have a high degree of oxidation, and are not safe for the human body. They need to be used under the guidance of professionals, and ordinary people are not safe to use at home.
Misunderstanding 2 Eating Banlangen to prevent influenza H7N9 bird flu in SARS to the present, once respiratory infectious diseases strike, people will always think of Banlangen.
Some families always have Banlangen. When they heard that the flu was coming, they immediately rushed two packs to each family.
Wang Tong said that Banlangen does have an antiviral effect, but it is also a medicine and there are alternatives.
In addition, Banlangen does not prevent the flu, and people with spleen and stomach deficiency should not take it.
Excessive intake will cause adverse reactions to digestive and hematopoietic functions.
Misunderstanding 3 Steamed vinegar disinfection and anti-influenza room steamed vinegar to prevent colds is extremely prevalent during SARS.
To this day, many people still believe that closing doors and windows tightly and pouring vinegar into containers such as casseroles and boiling can be sterilized.
Ms. Sun poured vinegar into the house to make a beauty steamer, thinking about using steam to disinfect the air in the house.
As a result, the family had difficulty breathing, uncomfortable throat and nausea after smoking.
Wang Tong introduced that whether “fumigation vinegar” can cure virus infection is still controversial so far, and there is no scientific evidence to prove that vinegar fumigation has a reliable killing effect on bacteria and viruses.
If smoked vinegar is inhaled in a closed space, the concentration of vinegar in the air will not only cause symptoms such as dyspnea and nausea, but also cause damage to the skin and mucous membranes of the respiratory tract.
“Because acetic acid has a stimulating effect on the respiratory mucosa, it can lead to aggravation of patients such as bronchitis, emphysema, and hypertension. Therefore, patients with chronic respiratory disease at home should not be smoked with vinegar.
Myth 4: After you get the flu vaccine, you won’t have a cold. Influenza is an acute upper respiratory infection caused by the flu virus.
Influenza vaccines are only effective against one or more viruses that cause influenza and have no effect on the common cold caused by cold.
And it needs to be reminded that the effective period of the flu vaccine is only one year. Due to the continuous mutation of the virus, the flu vaccine is not necessarily the same every year. Therefore, after one year, it needs to be re-vaccinated.
After the vaccine, it takes half a month for the body to produce antibodies.
During this period, patients with weak resistance will still be recruited if they encounter the flu virus.
Some people think that the flu vaccine is not 100% effective, so what am I doing?
As a result, Wang Tong said that the flu vaccine is currently the most effective way to prevent influenza. Because influenza itself is not equal to the common cold, it can aggravate underlying diseases and cause secondary pneumonia, which is easy to appear.Various complications and even life-threatening.
Therefore, he still recommends that the elderly, children, pregnant women and frail people be vaccinated once a year.
How to properly prevent a cold Wang Tong said that to prevent a cold, first of all, you must keep your home clean and hygienic. Some elderly people like to pile up debris at home, and even pick up trash to go home to collect.
This practice can easily bring germs into your home and affect your health.
The bedding should also be sunbaked frequently to prevent virus invasion.
Washing your hands frequently is also necessary, especially after touching your nose and other secretions, and you must wash your hands immediately with running water.
In addition, drinking plenty of water, maintaining a moderate amount of exercise, ensuring excess sleep, and not going to crowded places are the best magic weapons for preventing colds.
