There may be many people wondering how Is the novel coronavirus infection (SARS-CoV-2), known as COVID-19, can be relapse? If yes, will I have immunity? Today we will take into account the scientific evidence.
After we got to know the emerging disease COVID-19 Which is now spreading all over the world More than four million people caught. And almost three hundred thousand deaths already In Thailand there are thousands of primary infections. And some people died and had severe symptoms Diagnosis and follow-up to see if it's cured or not The standard is now the genetic material of the virus in the human body, such as the mucous membranes of the nose or throat. And various secretions by molecular means, known as PCR (polymerase chain reaction), has also been developed to monitor the body's immune level against bacteria. By measuring the antibody level in the body Which is used as a guide along with molecular methods And is currently being studied for future diagnosis and follow-up.
At the moment, there are many patients who may have the SARS-CoV-2 virus genetic material, which remains positive for a long time. Or it might have a negative result and then add it back up again. It is reported in the International Medical Journal. It is reported from China that a 46-year-old woman has recovered from the disease. Molecular assays were performed twice before being positive. Even without fever and general symptoms are fine. Therefore it is possible that Dead genetic material remains in the body system and does not cause pathogens.
But still can be found when using detailed molecular methods (Reference document 1) There is also another report. Six more people who have recovered from COVID-19 have been tested repeatedly and have molecular testing. Four of them did not have symptoms. One had a slight cough. And another one had obvious symptoms: fatigue, fatigue, muscle pain, cough, mucus, etc. (Reference 2).
There were many patients who came to be examined after they had recovered. That they are immune to this disease But at this time, data is not enough to say how long this immunity will last. Therefore asking those who are and have been healed Acting in isolation from others (self-isolation) for 30 days from the first day of symptoms. Maintain personal hygiene and in residential premises When the time has passed If there are no symptoms of any kind, social measures must be taken by keeping a physical distance from others (social distancing) wearing a mask. Take care of your hygiene and your health to be healthy. If symptoms repeat, see your doctor for further investigation.
