How many are actually infected?

This is a very basic question, but the answer is not easy.

Novel coronavirus infection has already been detected in millions of people. However, many researchers believe that number is only a fraction of the total.

Adding to the confusion is the number of patients who have had an infection but have not had symptoms.

When a person is infected with a virus, their body usually produces antibodies against the virus. If a good way to make those antibodies is found, then maybe in the future you can get a better idea about the number of infections.

How deadly is this virus?

It is not possible to say the exact death rate without knowing for sure how many people have been infected. According to statistics, the death toll in different countries is less than 5 percent so far. However, if the number of patients who are infected but do not show symptoms, the mortality rate will come down.

What are the symptoms?

Fever and dry cough are the primary symptoms of the novel coronavirus disease Covid-19, which is thought to be contagious.

There have also been reports of sore throats, headaches and, in some cases, diarrhea. In some cases, the patient's ability to smell has also been reported.

Symptoms such as colds or sneezing, which are common in the common flu, can be seen in many people.

Research has shown that many people carry the virus unknowingly and spread it to others because they do not show symptoms.

What is the risk of spreading this virus from children?

Coronavirus infection in children is not uncommon. However, statistics show that the incidence or death rate of children infected with the virus is much lower than other age groups.

At risk, children and adults are more likely to be infected. Because they go to the adults, go to play on the field.

Researchers are still unaware of the extent to which Kavid-19 is spreading among infected and dying children.

Where did the novel coronavirus come from?

The virus is thought to have started at the end of December at a market in Wuhan, Hubei Province, China, where wildlife is also traded.

The new virus, a relative of SARS coronavirus, is also being called SARS-COV-2. Although the virus was found in Badur, it is believed to have entered the human body through an intermediate animal.

But that link is still not clear to researchers. And as long as it remains unknown, the risk of new outbreaks will remain.

Will the incidence of the virus decrease in the heat?

In winter, fever and cold easily overwhelm people. This problem is less in the heat. However, researchers have yet to find a definitive answer as to whether the novel virus infection will decrease in the summer.

Scientists in the United Kingdom say it is unclear how much seasonal changes will affect the virus. However, if the effect persists, it is more likely to be less than that of the common cold or flu virus.

If the rate of infection actually drops significantly in the summer, there is also the risk that the rate of infection may increase again in the winter. At that time, the hospital is crowded with ordinary flu patients.

Why is someone's condition critical?

Most patients with coronavirus experience mild illness. However, 20 percent of the illnesses become serious.

One of the reasons for this may be the person's immunity. The more active that power is, the lower the level of illness may be. Genetic makeup can also be important. If these issues are understood, the patient can be treated without leaving the ICU.

Once he recovers, can it happen again?

Scientists do not have as much evidence as there is speculation in this regard. Once someone's immune system wins the fight against the virus, there is no guarantee that the antibody will last.

So far, there have been reports of some of the returnees recovering. In that case, there is a possibility of mistakes in the test. This means that the patient may have been infected when the coronavirus test was negative and the patient was being discharged.

And since researchers are only three months old with the virus, they do not have enough data to confirm it.

However, it is important to decide on antibodies to deal with the virus in the future.
