Hi noted your history, covid symptoms usually develop 5-15days after exposure.please get tested if you become symptomatic and develop cough ,high grade fever,body pains etc.

Hi noted above history. As the cases of covid pandemic is increasing day by day .And the process of unlock has already begun . As long as you wear the mask ,maintain the social distancing and hand and respiratory hygiene and as you mentioned the dentist has wear a PPT then very less chances to get contracting. The risk or fear is getting is everywhere as you step out of your home.

Do a online consultation with a pulmonologist for further evaluation

its just fear of covid..though need to be careful and monitor symptoms..fever cough or breathing difficulty.. incubation period for covid is 2-14 days. take care!!
