Much remains to be learned about coronavirus disease (COVID-19), which lately is wreaked havoc around the world. Although scientists are slowly gaining more Severe Acute Respiratory Syndrome (SARS-CoV-2) Coronavirus 2, it is unclear whether inflamed once can provide lasting immunity to the new coronavirus.
New cases of reinfection have been reported worldwide. Today, a doctor at Tel Hashomer Sheba Medical Center, Israel’s largest hospital, performed a SARS-CoV-2 test 3 months after recovering from coronavirus disease (COVID-19).
The doctor contracted the virus in April in full swing of the pandemic in the country. In May and June, swab tests showed that the doctor had fully recovered from the disease. However, when the doctor re-tested in July, the effects were back to positive.
A hospital spokesman said the doctor had tested him as he still had traces of the first virus discovered in his blood. During his April attack, the doctor experienced fever, cough and body pain, but has since recovered from the disease.
However, in early July, the doctor contacted a proven case of COVID-19, and then tested positive for SARS-CoV-2. This case is the newest in a series of possible re-infection incidents, raising questions about the duration of immunity against SARS-CoV-2, or whether there is one.
Recurrent cases of coronavirus have been reported in other countries, adding Canada, Japan, South Korea and the United States. In these countries, some patients who had recovered in the past from COVID-19 re-inflamed with the virus after 3 months.
The profile of the reinfection instances raises considerations that antibodies that evolved through the framework opposite SARS-CoV-2 would possibly not necessarily be the framework of long-term infections. If the antibodies supply ions, they may not last long. Therefore, the new data highlight the need for an effective vaccine to supply the mandatory ion opposite to the new coronavirus, which has now inflamed more than 14.63 million people and killed at least 608,000.
Can you imagine reinfection in other people who had become inflamed with the coronavirus? An examination published in May through scientists from Columbia University’s Mailman School of Public Health found that endemic human coronavirus reinfections are not uncommon, even within a year of the previous infection. The team studied 4 other types of coronavirus.
In addition, many studies look for how long the coverage provided by antibodies will last. For other coronavirus infections, such as severe acute respiratory syndrome (SARS) and Middle East Respiratory Syndrome (MERS), those who recovered had some form of immunity for about a year or more in others. When it comes to other forms of coronavirus, which circulate regularly, the era of immunity is shorter.
Another recent study also explored the duration of SARS-CoV-2 immunity and found that antibodies protect about 3 months on average. This will make the progression of the vaccine more complicated as vaccines are being tested lately to determine its protection and efficacy. Without an express era of immunity, some vaccines might not work as effectively.
Israel, for its part, has introduced large-scale serological controls or antibody controls on the extent of the pandemic. Because there is a threat of reinfection and antibodies disappear over time, governments and government deserve not to use antibody control as a price ticket for immunity.
To date, Israel has recorded more than 52,000 cases of COVID-19 and 415 deaths. Meanwhile, the United States reports the number of infections, with 3.81 million other people and more than 140,000 deaths. The other countries with the highest number of instances shown are Brazil, with more than 2.1 million instances, and India with more than 1.11 million.
