adopted a dynamic clearing policy, which made it difficult for everyone to come into contact with the virus . In addition, the disinfection work was in place, and generally people would not be infected with the new crown .
But now the policy of "full liberalization" has been implemented. In the early stage of full liberalization, many people were infected with the new coronavirus. Walking on the street, you can see people coughing everywhere, and many people even said that even the air was positive.
However, there are still people who get Yang even when they stay at home. It is understandable that they get Yang when they go out, but why do people who stay at home also get Yang? Can the air also spread?
Why do some people get sunburn even when they stay at home? Is airborne ? These points are easily overlooked
Not paying attention when picking up groceries
Since the implementation of the comprehensive liberalization policy, many people have stayed at home and dare not go out, but they still have to maintain normal daily life, so going out to buy groceries is a must.
If there are many infected people upstairs, but you don’t wear a mask when you go out, or you don’t fully disinfect yourself after returning home, you will be easily infected because the protection is not in place.
Nowadays, the new coronavirus is spreading very quickly. Even staying at home is not safe. At home, you must not only open windows for ventilation in time, but also disinfect in time to reduce the probability of virus infection. At the same time, try not to order takeout and shop online, because foreign things can easily bring the virus into your home.
Aerosol transmission
The transmission methods of the new coronavirus include airborne transmission, aerosol transmission, contact transmission, fecal-oral transmission. Staying at home can also cause Yang, probably because aerosol transmission.
The air flow in the corridor is poor, viruses may be present in the air, and aerosols may be spread through drainage and ventilation systems, such as sewers, and aerosols can easily enter every household along with the airflow.
How long can the new coronavirus survive?
The reason why the new coronavirus can maintain high infectivity is because of its extremely long survival time outside the body. Studies have found that the new coronavirus can survive for about 5 days in a dry and well-ventilated environment, so the new coronavirus has more time to spread widely.
In the internal environment, the nutrients and environment will be more suitable for the growth of the virus, and the coronavirus will remain longer. Most people will show signs of symptom relief within 10 to 15 days after being infected with the new coronavirus.
In other words, the virus can survive in the human body for half a month. If the infected person is older or has weak physical fitness, the virus may survive longer. After COVID-19 patients are treated, residual RNA and metabolites of the virus may remain in the body for several months.
Why do some people have mild symptoms while others have severe symptoms after becoming infected?
Everyone’s immune system is different, so the clinical symptoms are also different. Different symptoms often appear after being infected with the new coronavirus, which can be roughly divided into the following categories.
Asymptomatic infected persons : The virus is present in the upper respiratory tract, but there are no symptoms.
Infected patients with mild symptoms: upper respiratory tract infection and slight fever, but pneumonia will not occur.
Common symptoms: This disease is relatively typical, and most of them will have fever respiratory symptoms.
Severe symptoms: Some patients will have severe symptoms after being infected with the new coronavirus, and their condition will suddenly worsen, or even cause problems quickly.
This is because everyone's immunity is different, so the symptoms are also different. Academician Zhong Nanshan once said that everyone should strengthen their immunity, maintain a peaceful mind and do moderate exercise to improve their own immunity and better prevent and control new coronavirus .
extension - Can I take a shower after being positive for COVID-19?
Some experts recommend not taking a bath after being infected with the new coronavirus to avoid prolonging the course of the disease, because the immunity is very low during the new coronavirus infection. Taking a bath at this time will consume physical energy to expand blood vessels, and will also cause the body to lose water, aggravating the symptoms of a cold.
When a high fever or acute fever occurs, it is not recommended to take a bath. If you feel uncomfortable without taking a bath, you can clean the local area, otherwise the condition will be prolonged, which is not worth the gain.
In addition, it is best not to wash your hair after being infected with COVID-19. Some people washed their hair directly after testing positive for COVID-19, and developed symptoms of "cement-sealed nose". If you must take a bath or wash your hair, be sure to increase the temperature of the room and avoid freezing.
In short, for the sake of your health, try not to take a bath when is positive and is positive. If you feel uncomfortable, you can use hot water to rinse the area, but not the whole body.
