COVID: Why are so many catching the virus again?
However, experts have shown that even if you find out you have COVID for a second time it is less likely to cause serious illness.
In the early days of COVID, which is back in 2020, it was very difficult for a second infection. And 2 years on, it's not the same now. Most people who have this disease prematurely get it for the second or third time. Reports suggest that it is for 3 main reasons - firstly the decline in vaccination rates; secondly, the omicron variant, and thirdly, the game of numbers.
Decreased immunization policy:
The chances of a person re-becoming infected with COVID-19 increase with the decrease in immunity to the coronavirus vaccine. Even the World Health Organization (WHO) has indicated that this will happen which is why we are taking more than one vaccine.
“As we enter the 3rd year of the epidemic, we expect to see some decline over time. It depends on the type of vaccine you have taken, the number of dosages and the age and the conditions available, ".
Omicron variants:
Omicron varieties, both BA.1 and BA.2, are phylogenetically very different from previous varieties.
This difference offers a better chance of sneaking ahead of the original immune system, which was based on exposure to previous Covid infections, the BBC reported. "Thus the rate of re-infection has increased almost tenfold this year compared to the rates seen at the beginning of the epidemic."
Total number of cases:
Part of it is a game of numbers. Many of us are already infected at one time or another, so much so that a growing number of new infections are on the rise, according to the report.
However, experts have shown that even if you do get a second infection, there is little chance of developing serious illness. Immune expert Professor Eleanor Riley said in such cases ... "it means there is an infection in your nose and throat."

Prevention offered by vaccination or previous infections is more effective in preventing the virus from invading your body and causing serious damage, rather than keeping the virus out of your nose and throat.
Here's what you need to know about Shanghai closure:
Despite tight closures, new cases of COVID-19 in a densely populated city in China jumped by a third last week. Following this, officials imposed a ban separating the city near the Huangpu River, separating the historic center west of the river and the eastern financial and industrial region of Pudong to allow mass exploration.
While eastern residents have been closed since Monday, those in the west were scheduled to begin their four-day closure on Friday. Many residents living in the western region on Tuesday received notice from their housing committees that they would be barred from leaving their compounds in the next seven days. The southwestern state of Minhang will suspend public bus services until April 5.
Shanghai on Wednesday reported a record 5,656 asymptomatic COVID cases and 326 symptomatic cases on March 29, up from 4,381 96 asymptomatic cases and 96 new cases with symptoms of the previous day. Shanghai officials told a news conference Wednesday that since the start of the strike on Monday, they have tested 9.1 million nucleic acid tests.
Across China, daily statistics of new local infections in the past two weeks have been significantly higher than those seen in the first two months of this year, marking the biggest wave since the 2020 Wuhan-focused surgery.
China's "flexible authorization" approach means it aims to clear all cases, and all people found to be infected are sent to solitary confinement or to hospitals. Close contacts with neighbors should be kept separate from the home.
