Am scared to death

Yesterday the ambulance took my neighbour and her children because she's infected with covid 19. We are told not to go out of our apartments or get in contact with anyone. Am really scared because I have been to close to her children. I am asthmatic and so scared to think if am sick or not. I cannot sleep and so worried. Is there any thing to be done before the results come back they did take test of all of us. Is there anything I can do at this moment.
