Even though COVID-19 is an infection of the respiratory system, the contagious coronavirus can affect several organs at a time. In most cases of COVID-19, the symptoms disappear in 15 days. Only those suffering from severe infection have to deal with the nasty symptoms for months, which is often referred to as long COVID.
Long COVID was seen commonly during the Delta wave. As the infection was highly threatening, it led to severe symptoms and the virus variant was more fatal than the ancestral strains of coronavirus. Compared to Delta, the Omicron variant is less deadly. However, an important question that still needs to be addressed is can infection from Omicron variant lead to long COVID as it was the case with the previous variant.
