For weeks, the same awkward scene played out again and again in sexually transmitted infection clinics across the United States. Half-naked gay men stood with their pants around their ankles while clinicians crouched between their legs, swabs at the ready. The clinicians were covered head-to-toe in hazmat chic: gowns, gloves, face shields and N95 respirators. The men were covered in something much worse: painful lesions, on their genitals, their anuses and sometimes even their faces and limbs.
It was July 2022, just last summer, and an outbreak of mpox — formerly known as monkeypox — was in full swing. From a handful of cases in a few cities in early May, the outbreak surged to more than 16,000 cases in 75 countries and territories just two months later. It was terrifying.
The sudden appearance of so many mpox cases everywhere and all at once was shocking. Aside from an occasional case among travelers from countries in West or Central Africa, where the virus is endemic, mpox was extremely rare in Europe or North America. The U.S. had seen only one outbreak, back in 2003, among Midwesterners with pet prairie dogs that had been housed with infected African rodents. There were 47 cases then and no documented cases of human-to-human transmission.
This time was different. In early May 2022, mpox found its way to gay raves in Spain and Belgium, huge annual parties that draw men from all over the world. Clothing was scant, grinding was plentiful and when the parties were over everyone flew home. Within weeks, mpox cases — resulting from human-to-human transmission — began cropping up in cities worldwide.
While the outbreak caught the public unaware, public health officials had been warned. Five years earlier, Dr. Dimie Ogoina had observed unusual cases in Nigeria, first in an 11-year-old boy and then among young men who'd reported multiple sex partners or encounters with sex workers. He soon realized that this was not "the regular monkeypox we know" and tried to alert the scientific community about the possibility of sexual transmission.
And just as we were grappling with proof that Dr. Ogoina was right about everything — right that something had changed, right that mpox was transmitted sexually and right to raise the alarm — testing revealed that the mpox virus could survive on linens or clothing for more than two weeks. While we were both primarily concerned for those already suffering from mpox and those at highest risk of contracting the virus, we feared what might happen if mpox made its way into hotel rooms and onto cruise ships and college campuses. (Think of all those frat house couches that are rarely cleaned.) This outbreak could become an epidemic, perhaps even a pandemic.
