Not just a gay problem for sure but in practice definitely a high risk group. Avoiding that fact because there are idiots who think gay is a choice is more harmful to gays than acting appropriately. Gays and transgenders with high health risks in NL are eligible for a free hiv prevention shot, hiv-PrEP, and that same group is now eligible and called for a pox vax shot. In total roughly 32k people including sex workers. Which will be too late for upcoming Pride parades and pink festivals that will attract hundreds of thousands from all over the world and undoubtedly cause an explosion in cases.
If this started with a few heterosexuals some people would blame vaginas cause it wouldn’t spread as fast in the gay community. First 256 cases in NL were men who had sex with men. That’s the result of the first infections being men who had sex with men and sex being an effective way to spread. 99% of current cases in NL had gay sex with an infected person. So far it is practically a gay std and hence treated as such, with yes constant disclaimers that doesn’t mean others can’t / don’t / won’t get it.
