Hong Kong Reports The First Reinfection Case of COVID-19

by StartupWorld Staff         

Various scientists and doctors are continually learning about the immunity of the body to COVID-19. However, doctors now believe that if an individual has been exposed to the virus, that person may be immune to the virus for a few months due to the presence of the antibodies and immune for potentially longer duration due to white blood cells called B Cells and T Cells. The doctors and scientists also consider the reoccurrence or the reinfection to be rare. 

However, recently, the University of Hong Kong researchers have reported that they got the first confirmed reinfection case. As per the leading publishing firm, a man aged 33 years, who was 'young and healthy,' had the first time saw the mild symptoms such as cough, fever, sore throat, and headache. His initial COVID-19 infection was found in reinfection four and a half months earlier, and reinfection was discovered on 15th August after returning from Spain via the UK. 

Researchers stated that he likely got the COVID-19 strain circulating through Europe in July and August, and he had not reported any symptoms around the second time.

It has been theorized that a few people, who are already recovered with the coronavirus could test positive for weeks due to the prolonged viral shedding. According to the leading publishing firm and the University of Hong Kong's clinical microbiologist Kelvin Kai-Wang To, MD said their results prove that his second-time infection is occurred by a new virus that the man got recently instead of the prolonged viral shedding.

Now the question is, what does all these means? A group of researchers also thinks that the COVID-19 strand, which this man got for the second time, is not linked to the initial COVID-19 infection. The researchers mentioned that the findings also show that COVID-19 could be similar to the common cold symptoms of coronaviruses (which typically only offers immunity for 3 to 6 months and a maximum of less than a year) and could circulate 'even if the patients have got the immunity through the natural infection or through vaccination.

World Health Organization's (WHO) COVID-19 technical lead, and an infectious disease epidemiologist Maria Van Kerkhove said that the doctors and scientists team shouldn't have jumped directly to the conclusions with this Hong Kong case alongside this, WHO's team is still reviewing it, a publishing firm reported. Maria said that what they have learned about the COVID-19 infection is that people develop an immune response, which is not entirely clear yet. How strong the immune response is and how long the immune response would last.

Moreover, Yale University's School of Medicine's professor of immunobiology Akiko Iwasaki, Ph.D., said that this case should not source any concern. Late, Akiko tweeted an excellent news article stating that the Hong Kong case is a classic example of how immunity should work. Still, the immunity was not enough to block COVID-19 reinfection; it actually protected the person from the disease. (the man was however asymptomatic the second time).

Dr. Akiko Iwasaki further stated calling it more good and encouraging news that at the time of reinfection, the patient had no detectable antibody; however, the antibodies have developed detectable antibodies after reinfection. However, it is no cause for alarm. She further wrote that more research is required on the range of reinfection that needs to be done entirely.
