Hi doctor, I am copd patient, I have done first test on 25th april, from this day to until now (18th may) I am in an isolation camp in dubai under observation of dha. Physically I was well all these days and have no any specific symptoms of cavity yet. Sometimes I will have small headaches and coughs but it will not last long. Within these days dha taken 6 swab test samples and the results was 1 negative and 5 positives. Why it is happened like that? I am very curious to know the cavity status in my body.
