Firstly if your brother and his wife can get tested for covid either by going out or asking any know lab person or by booking online which ever is earliest and easily available then well and good.
If not then ask them to take dolo 650 one tablet for your brother and one for his wife, or any other tablet with plain paracetamol composition. It will help with fever and body ache. And for soar throat gargle with warm water with 10 ml betadine solution or one table spoon of salt. And take steam inhalation by putting pudina leave in hot water and inhaling the steam.
Secondly as for the baby, please consult a pediatric doctor as soon as possible as fever in babies is something to be worried about, high fever in babies can cause seizures/fits so be quick with taking the baby to a pediatrician.
