Can you get the coronavirus again after recovering as cases reported second time in china etc. But it is impossible for Corona patients to be re-infected, experts claim - Why?

Can you get the coronavirus again after recovering?

Why are some patients sicker than others? Will the disease return every winter? Will the vaccine work? Can some of us go back to work with an Immunity clearance? What long-term measures are necessary to treat this virus?

While the number of COD-19 victims worldwide is increasing day by day, these questions are also being asked more and more. One thing all these questions have in common is the immune system and we know very little about it.

How can you develop immunity to the coronavirus?
Our body's immune system is a shield against infection and has two parts.

The first part begins with the identification of an external invader in the body. This is called the net immune response, in which white blood cells destroy infected cells and release chemicals that cause inflammation.
But this system does not affect the coronavirus. He doesn't understand it and therefore his body is not developing resistance against him.

Instead, you need an adaptive immune response or an immune response that changes as needed. It contains cells that make specific antibodies that fight the virus. There are also T cells that attack cells that have been infected with the virus, and this process is called a cellular response.

This work takes time. According to research, it takes about ten days for antibodies against the coronavirus to develop. These antibodies can build a strong immune system in people infected with the virus.
If the immune response that changes as needed is strong enough, it can have a lasting effect on the virus, which can protect you from it in the future.

However, it is not clear whether people with mild or symptom-free symptoms can develop an immune response that changes as needed.

How long does immunity against the virus last?

The immune system's memory is similar to ours. It clearly remembers some infections and forgets some.

Like measles infection is memorable. Once vaccinated, you should not have the disease for life. However, experts also say that people of a certain age should be re-vaccinated with modern vaccines. But there are many infections that the immune system cannot remember, such as recurrent respiratory illness in cold weather in children or the flu or the common cold whose virus changes form.

The new coronavirus, known as Code-19 or SARS-CoV-2, which affects the world, has not yet been known for how long immunity can last. The other six coronaviruses that infect can be estimated. Four of them cause symptoms of the common cold and the duration of immunity against them is short, and research has shown that some patients are infected with the virus twice a year.

But the common cold is not so severe. In contrast, the two coronaviruses are more disturbing. These are the viruses that cause Sawyer Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). These antibodies have been identified many years later.

"The question is not whether your body has immunity, but how long it lasts," said Professor Paul Hunter of the University of East Anglia. "It's definitely not a lifetime," he said. Research on SARS antibodies has shown that immunity lasts for one to two years and that is not certain.


However, they also say that even if you do not get rid of the virus completely, the second time the effect will not be as great as the first time.

Have people fallen victim to COVID-19 again?

There are reports that people have contracted corona again shortly after recovering.

A 70-year-old patient of Corona in Japan is the person who made the doctors aware of the disturbing facts in this regard. The patient was isolated in Tokyo in February this year after Corona was confirmed.

The Japanese news agency NHK says the man returned to his daily life after recovering, but a few days later he fell ill again and developed a fever. He returned to the hospital and was shocked to learn that he and his doctors had been diagnosed with the coronavirus again.

One idea is that the patient may have actually contracted the virus again, while another is that the virus lurks in the body and re-invades after a while. However, the scientific consensus is that this could be a test error and the patient was mistakenly told that he was no longer infected with the coronavirus.

So far no human has been deliberately infected with the coronavirus for testing for immunity, but some monkeys have been tested. The virus was injected twice into the monkeys' bodies. Once to form an immune system and then three weeks later. These limited experiments showed that the monkeys did not show any symptoms of the disease when they were re-injected.

Am I safe if I have antibodies?

There is no guarantee that this is why the World Health Organization (WHO) has said that governments should not issue certificates to people who have recovered from the coronavirus, stating that the person's body is immune to the virus. Has been created.

The purpose of issuing this immunity passport is to ensure that those who are found to have antibodies to the virus in their body can return to work. This can be important for staff working in hospitals and care homes. But where you will find some antibodies in every patient, they are not all the same. Neutralizing antibodies are the antibodies that attach to the coronavirus and prevent it from infecting other cells.

According to a study of 175 people who recovered from Corona in China, such antibodies were found in very small numbers in 30% of them. That's why the World Health Organization says, "cell immunity is critical to recovery."


Another problem is that even if antibodies protect you from the coronavirus, you can still spread the virus to other people.

Why is immunity important?

It is important to know how often and how often Code-19 can affect you. Your immune system can also be affected by the virus. If people are able to prevent it to some extent, it will make the disease less dangerous.

If it is difficult to develop long-term immunity, it may result in difficulties in vaccine preparation or it may affect the method and duration of vaccine use. And the period of immunity, whether it is due to an infection or the use of a vaccine, will tell us how successful we can be in stopping the spread of the virus.


These are big questions that we do not currently have the answers to.

It is impossible for Corona patients to be re-infected, experts claim from Seoul, Korea

Seoul: Health experts have claimed that a patient with the deadliest COVID-19 virus cannot be infected again once he recovers.

According to a report by a foreign news agency, the coronavirus epidemic has infected millions of people around the world, causing widespread panic. However, due to the hard work of doctors, more than one million patients have recovered. Have also happened.

Experts from South Korea have claimed after a study that a patient infected with the deadliest coronavirus could not be infected again, following a suspicion that raised concerns. In South Korea, Japan, and China, people recovering from the corona are again falling victim to the virus.


Experts said that the second time the diagnosis of a deadly virus in healthy people is the result of a testing error.

Please be safe
