Where did STI/STDs come from? Since they are created via giving to someone who has already contracted it
So where did they originate from?
In: Biology
The sexual route of transmission – body to body via bodily fluid exchange is for the structurally most feeble microbes and viruses that can’t survive for any period of time in water (eg streams, wells), on surfaces, or in exhaled / sneezed/coughed out droplets.
They are so feeble they literally need to go directly from one person into another with no outside time at all.
While they may be structurally feeble they can surely be deadly if left untreated eg HIV, syphilis, HPV infection (via causing cancer).
Like most infectious diseases they mostly if not entirely come from other species originally and hopped the species barrier into humans. In the case of HIV it is believed to have come from the practice of preparation and consumption of ‘bush meat’ the meat of various primates and monkeys and crossed into humans most likely in the 1950’s in central Africa.
