Initial reports suggest that the Omicron variant causes mild infection, but there is no conclusive data on the severity of the symptoms.
Epidemiologists and science experts say that there is too little data to conclude whether the new variant can cause severe infection. Preliminary data from South Africa where the variant was first detected suggests that the cases are typically mild. The symptoms range from dry cough, fever, night sweats, and severe body pains similar to previous variants. But different variants of the virus can trigger various symptoms. No information suggests that the symptoms associated with Omicron are any other. Whether a person infected with the Omicron variant is vaccinated or not might also determine the severity of the symptoms. According to WHO, understanding the Omicron variant's severity level will take days to several weeks. Thus, presently we cannot objectively verify the severity of the symptoms caused by the Omicron variant of SARS-CoV-2.
