In an emergency situation, I accompanied a boy to the hospital after he fell from a building. Five hours later, he was declared COVID 19 positive. We were shocked because his main issues were trauma related, with loss of consciousness and inability to use his hands and legs. How reliable are RTPCR and Rapid Antigen Test results in such situations? How does this affect people like us who were asymptomatic but in close contact? Can an asymptomatic person spread COVID 19, and if yes, for how many days are they contagious?

Asymptomatic individuals can spread COVID, especially 2 days before symptoms and up to 10 days after infection. RTPCR is reliable but can rarely be false.

I and my family tested positive 5 days ago and we got admitted in the hospital the same day. My sister did not have symptoms for the first three days but later after medication she developed flu, cold, cough, nausea and extreme tiredness. She also feels shortness of breath but her oxygen level is constantly 99. Why is her body getting worse day by day? Even after injection she feels tired and fatigued. Her CT and blood report are normal and she has no fever. She is 26 years old. Does she have any problem?

On day 6 after infection, I did an RTPCR test. Today is day 10, and my report has come back with a Ct value of 22/25. I do not have any significant symptoms now, and my sense of smell and taste are normal. Should I be concerned about this Ct value?

Hi, I want to know. I got a COVID rapid antigen test after my blood report showed CRP at 52.4. My result was negative. Is this not the final result of my COVID test and do I have to wait for another report? If so, what is the other report if this is negative?
