Hello Aspirant,

See if your brother belongs to any of the conainment zone then only he can get the extension and he can wait for another way which will be decided by the NTA as aa alternative of this attempt of JEE-Main but if it is not so then your brother should reach at his center on the date mentioned on the admit card any how.

There will be no relaxation for those candidates who are not in containment zone or did not get infected form Coronavirus.
