Coronavirus: Sequelae, Prevention, Treatment, Spread, Questions on Coronavirus and COVID-19 You Must Know

2020-05-14

Unfortunately, if you go out and are infected by Coronavirus, you should know that young people generally have strong resistibility to virus, and just drink more water and take some medicine comply with the instructions of doctor if there are not many symptoms of heart, kidney and liver. Otherwise, you have to go to the nearest hospital asking for special treatment.

Many patients recovered well overall, including the lungs. The sequelae of novel coronavirus pneumonia is better than SARS, despite of those with critical serious symptoms patients whose bleeding, kindneys and lungs have been damaged a lot by COVID-19. So far, the damage to human body by coronavirus looks recoverable in a long term after recovered.

4 Points to Containing the Spread and Infection

Good and Early Self Protection by wearing face mask, keep safe social physical distance, washing hands frequently after touching anything else and disinfect the room and work space regularly.
Know the symptoms of COVID-19, and go to hospital or see a doctor in case of any suspect symptoms of COVID-19. In this case, you may get the right advise from doctor on time.
Get diagnosed as soon as possible by Nucleic Acid test and antibody test. This is critical to make sure you are infected or not, but it is difficult for many people to get tested for the shortage of test service and test kit in the country. It is the real life, but keep calling the emergency medical service and staying hospital for further test and treatment.
Once confirmed, isolation is necessary for you, and those who have been close contact in past 14 days. At least, you should let every one know, and tell them to do test, and self-isolation. It is not saving your life, but all the others’ life around you.

Spread and Transmission

As found, the mainly route of coronavirus spread and transmission is droplets, close contact and touch. As long as we avoid those, the infection could be avoided mostly.

Something must be noticed that the contagious nature of the virus is serious and exceed the normal expectation. In terms of infectiousness index, the general influenza is 1, SARS (SARS) is close to 2, the Middle East respiratory syndrome is 1.5, and the novel coronavirus is 3.

In general, the survival rate and activity rate of the virus under high temperature are relatively poor, so with the arrival of summer, the activity of the virus will decline, and the epidemic situation will generally decline. Although ultraviolet light is not as strong as ultraviolet light disinfection, high temperature is detrimental to virus activity and spread. As known, mosquitoes can transmit many viruses, malaria and dengue fever for example. But there is no evidence that the novel coronavirus will be spread by mosquitoes.

Will the storm and snow accelerate the spread of the virus? No. The gusty wind will definitely not increase coronavirus spread. The virus will quickly dilute, and after dilution, it will not spread if it does not reach a certain concentration in the air. That is why in a open and with good air circulation the infection rate will decline a lot.

About Group Immunity

The latest reported in Europe, 20% of people have coronavirus antibodies, and the highest might be 25%. This percentage is far from the so-called group immunity. And in theory group immunity usually needs about 60 to 70% of people infected and with antibody found. It is a big number. However, 20% is not enough.

At the same time, no proved evidence to say group immunity works for COVID-19. There are lots of things of coronavirus unknown to people, and the scientists of virus. No one knows whether antibody would work, and how long it will work. The reasonable choice is try to control the spread and win more time to research and develop vaccine. Vaccine might be the final solution for the virus.

Only Dry Cough May not Be COVID-19

Take it easy, dry cough only does not say that you are infected with novel coronavirus pneumonia. Cough is a common symptom of many diseases. Dry cough is generally a symptom of acute bronchitis. It is not the earliest symptom of flu. It is recommended to go to the hospital clinic for nucleic acid testing.

Distinguish flu and COVID-19: Testing is Accurate

Last year, There was an outbreak of influenza in United States. Influenza and novel Coronavirus Pneumonia have some symptoms that are very similar, so how should you distinguish between Influenza and COVID-19 in daily life?

Influenza has very similar to the symptoms of coronavirus. First, it is systemic. At first, the fever may account for more than 50%. Not everyone has a fever. The flu also has this situation. At first, the body is uncomfortable. Therefore, it is difficult to distinguish by symptoms alone. If there is no test, it is difficult to make a differential diagnosis.

For COVID-19, now the quick test if Nucleic Acid test and Antibody test. Nucleic Acid test need some more time, but could give enough information for early diagnosis. And later with antibody test will confirm if infected or not, which calls confirmed case.

Asymptomatic infection

The term asymptomatic infected person may not be very accurate. In fact, there are several situations. One is that people go to hospital and test nucleic acid positive. It is not called asymptomatic.

For asymptomatic infection, there is one kind. The one is the prodromal period or incubation period of this disease. It is generally three to seven days. During this time, he has no symptoms, but he is already infected. Three to seven days later, he had a fever and cough. In fact, this is called the incubation period, or the prodromal period. This is definitely a type of coronavirus infection.

Some one with light symptoms are taken as asymptomatic infections as well. Those guys have light symptoms, feeling tired, muscle pain, and sleepy, but they do not go for testing, just take some medicine to eliminate the uncomfortable symptoms.

Asymptomatic infections are hidden around us, maybe they do not know they are infected. So, back to the first topic, do well self protection during the pandemic is the only way to prevent being infected.

Go Out Shopping

It is safe at home or in the dormitory, but it is very important to wear a mask when going out. As you know, we don’t usually wear N95 masks, nor do we need them. General masks cannot protect against the coronavirus because the virus is too small to be worn in the mask. But viruses rarely flow freely in the air, they attach to some things, and most of them stick to droplets and spread to others. General masks can prevent droplets, so we can prevent most viruses, and wearing a mask is quite useful.

The droplets won’t run too far, after coughing probably no more than 2 meters, more than this distance will fall to the ground. So up to now, viruses in the air cannot exist alone and freely, they are always attached to some substances.

Now most countries have realized that wearing a mask is afraid that others will spread it to themselves. This is a big change. Some countries have even introduced regulations for mask. Many countries in Europe are unblocking, but it is required to wear masks when going out, so everyone has accepted it.

Impossible to get infected in the plane and have symptoms immediately

Time on a plane is short, the longest might be 20+ hours, and it is impossible to experience symptoms after receiving an infection within 20 hours. It is too short to have symptoms at the same time, otherwise, you were infected days ago before you took this plane. COVID-19 has an incubation period of three to seven days. To prevent in the plane, please make sure you are in the best condition when take this flight, and pay attention to protection, wearing masks and washing your hands.
