Hindustan Times. “Having said this, children are still at risk of developing infection as they are unvaccinated till now. Especially Omicron which is known to be highly infectious." Symptoms: Regarding symptoms related to Omicron, the expert said that children who have been infected with Covid show predominantly an upper respiratory tract infection like fever, runny nose, throat pain, body ache and dry cough.
Protection: Since, children are yet to be vaccinated, following proper COVID-appropriate behaviour is paramount like wearing masks, maintaining social distancing, sanitizing regularly etc.
Also, the adults at home must maintain caution so that they don't bring the virus home. In case, your child shows cold-like symptoms or gastronomical disorder, you should refrain from sending them to school.
It could COVID or some other respiratory syncytial virus (RSV), and it can be hard for the child to handle, especially at a time when they are trying to adopt to a new environment.
