Quote: "The amendment states that foreign professionals, their family members living in Russia and any foreigner who wants to stay in the country for an extended period of time have to be tested every three months for infectious diseases, including syphilis, HIV, leprosy, tuberculosis, and COVID-19. They are also required to take a drug test and must submit their fingerprints and a biometric photo to the authorities."
Irony:
assuming you are living in country and have been tested a couple of times, the only place you are going to get those diseases is from the local untested populace.
