The BA.2 subvariant of the omicron variant has a unique set of symptoms that show up differently for everyone.Driving the news:Researchers recently conducted an in-depth analysis into reinfection risks from the BA.2 variant, investigating whether or not the BA.2 variant can infect people who already were infected with the omicron variant, per CNN.

• In the study, the researchers investigated 140,000 viral genomes from infected patients.
   
• They found there were 263 reinfections.
• The researchers found 47 people who had been reinfected with BA.2 after getting the original omicron variant.

Symptoms: Symptoms for the reinfected were across the board, according to CNN.

• Most reinfections were mild.
   
• Some people had no COVID-19 symptoms or mild COVID-19 symptoms.
• About five people suffered symptoms that were characterized as moderate, akin to flu-like symptoms, according to CNN.
• No hospitalizations or deaths were reported.

The bigger picture:A large amount of anecdotal evidence has suggested that the omicron variant can reinfect people, especially through the BA.2 subvariant.

• Yes, you can get omicron twice, Stanley Weiss, an epidemiologist at Rutgers School of Public Health, told Yahoo.
• He added, If you had a mild infection, didnt get a very good immune response, and you get exposed again with a big dose of the virus, its definitely possible.
