Hi my mother in law (61 yrs old) is having fever since 6 april ( she got vaccinated also same day). Earlier the fever was 99 so we thought it might due to vaccination but from 9 she is having 100 fever. On 10 april she got tested and report came as positive yesterday (13 april) . Her fever is not going below 100 even with 3 times dolo. Her oxygen level is varying from 93 to 96. Is there anything to worry ? Is hospitalisation required?
