And Viktor had to steal your kill xD <| sep |> You ' re making a straw man argument . I gave the example of hospital policies requiring gownsmasks for rooms of people that might have TB . Generally , if it ' s high up on the differential , doctors will put those contact precautions in place while testing . That doesn ' t mean they put it up for every person . If a patient comes in with a bloody cough , history of risk factors coming from endemic region , contact with TB individual , incarceration , homelessness , andor suspicious chest X ray findings they are likely going to be put into isolation . This is different from the situation you ' re describing where you ' re isolating people in the lowrisk population . Similarly , people working in the sex industry are at higher risk because they are more likely to engage in unprotected sex , anal sex , and have multiple partners .
