Up till now, COVID-19 infected more than thirteen million people across the world. Everyone has a question in mind that can the virus contract him again. It seems on a daily basis that there is a new story about a person contracted second time with the novel coronavirus.

One week ago, a physician from New Jersey claimed that two of his coronavirus patients contracted for the second time, only two months after their recovery from the first infection. Similarly, many other stories of the second infection circulated across the country, instigating people to question whether they completely safe from re-infection after the first spell with the virus.
Thus far, health experts say that these stories do not amount to proper proof. A professor of preventative medicine & infectious diseases at Vanderbilt University Medical Center, Dr. William Schaffner says that these anecdotes definitely not cause any alarm. They have the stories where the scientific root is partial, but it not actually tied in a nice red bow. It is not complete.
At present, experts are making efforts to understand just how long people remain safe from the fatal virus after their recovery from coronavirus. Infection with coronavirus, or any virus for that matter, ready the body to activate immune systems to attack the active coronavirus directly and also create antibodies, which may help protect the person against future infections.
The Coronavirus antibodies faded within a few months
Scientists are still unsure if it is possible for someone to infect for the second time. But according to two recent studies from China and the United Kingdom, found that the COVID-19 antibodies faded within a few months.
The first study from China published in Nature Medicine found that neutralizing coronavirus antibodies faded rapidly after two months in both symptomatic and asymptomatic people. However, according to the study from King’s College in London yet not peer-reviewed, found that neutralizing antibody response of COVID-19 may start to decline just three to four weeks after coronavirus symptoms initially appear. The King’s college study also found that patients with more severe symptoms show a more durable antibody response.
Even though these latest studies hinted that human antibodies might weaken faster than many hoped, health experts say that antibodies are not the entire story, and probably some other parts of the immune system might still perform some level of protection. Director of infectious diseases at South Shore Hospital, Dr. Todd Ellerin, says that the duration of immunity is not definite, but it may make sense that they may start seeing cases of second-time infection with the COVID-19, as with other common coronavirus infections.
SARS-CoV-2 or the novel coronavirus belongs to the family of coronaviruses that identified as to cause diseases from the usual cold to critical respiratory infections such as severe acute respiratory syndrome (SARS). Experts warned that immunity from a viral infection might vary as per its nature. It is a multi-fold process, but the exact length of immunity after coronavirus infection still not identified. There is certainly remains a chance that re-infection may occur for the second time.
