My husband is a police officer and was riding in a car with another officer for nearly an hour. The car broke down and they had to work on it together then get a ride back together in a car that came out to get them. During the time my husband told me the other officer appeared "hot, flushed and feverish." Three days later we heard that officer had tested positive for COVID-19.
Four days after exposure my husband was ill with an intense headache and malaise. But the symptoms went away within 48 hours. About a day after he got better I noticed that I developed a cough, sore throat and dizziness. But it was never incapacitating. I still have a cough though.
My husband is blood type O- and I am O+ and I am really beginning to think there is something to that.
Thanks for the info. Glad you are feeling (mostly) better and would be curious as to your antibody results. If it is transmissible with such relatively small exposure, Yike!
