Hi. Dr., I had sex with a prostitute and with condom during her oral sex to me and the intercourse. I m very worry because I got eczema on my scrotum and there is scratch on it. What if her fluid contact my scratch (not bleeding), would it cause the infection? I m so worry and want to have the RT-PCR examination, some clinics in my country claim that the window period of the RT-PCR been shortened to 10 days after sexual encounter, is that correct? Also, I afraid to infect family members during the window period but some reports say no need to worry as long as there is no sex, is that correct?
