Most of the cases so far are in men who are gay, bisexual or who have sex with men.
I hear 4+ of the cases have no travel history. No pre-symptomatic infection. Travels through mucus so sexual interation is one of the main causes (LDO I’m safe then). Traced in 4 euro countries and the US, any travel history traced back to Nigeria. Doesn’t really come from Monkeys, despite the name (rats, or rodents I think). Another zoonotic though.
