Covid Positive ( Mild Symptoms) Follow?

My mother was having few Symptoms like Cough, Fever, Mild leg pain & Mild Head Ache last Sunday night on the 25th April. We observed her symptoms if they go away and when it didn't we went for an RT-PCR test on Wednesday 28thApril Her Fever stopped on 29th April and didn't come back. Today vital paramters look as below however RT-PCR results from BBMP says she is Covid positive. Temperature: 97.7 Blood Pressure: @10am - 94/64 @12:30pm 107/90 Pulse - 95-110 Breathing rate - Normal SpO2 - 95+ As on today mild cough and cold still exist otherwise she looks healthy. She is in a strict home isolation with all the care she needs at home. What medication should I give her knowing she doesn't have any major symptoms at this time? How frequently do you suggest I capture her health status like temp, oxygen levels, BP..etc? What type of diet can she follow? Is hot steam vapourization okay to inhale/if yes, suggest frequencies. Thank you, Vikram
