الإجابة: B. Nasopharyngeal PCR for COVID)19
To establish the diagnosis of COVID-19 after a positive sick contact, send a nasopharyngeal swab for PCR - the sources use nasopharyngeal PCR for viral investigation and note COVID-19 is only distinguishable by PCR. Azithromycin and chloroquine are treatments (and not proven), not diagnostic steps; sputum culture is for bacteria.
