This is what one of the paragraphs said about the birthday party in 2018 (translated from Spanish)
"Scientists traced the first instance of person-to-person transmission. It occurred at a birthday party with approximately 100 guests. “It was a formal party, with tables and about 100 guests,” explains Gustavo Palacios, co-lead author of the article and a microbiologist at Mount Sinai Hospital in New York. Patient 1 attended the party but didn’t stay long—about 90 minutes—because he began to feel unwell and developed a fever.
Five people who had been seated nearby reported symptoms consistent with hantavirus pulmonary syndrome between 17 and 24 days after the party. “In fact, there was a sixth infected person who wasn’t seated nearby, and we didn’t understand why,” recalls Palacios. “But then we learned that they had met in the restroom and greeted each other there.”
One of those infected at the party, Patient 2, was the most likely source of six infections in other people after the party, due to his active social life. Patient 2 died 16 days after the onset of symptoms, and his spouse developed a fever during his wake. Another 10 people who attended the funeral and were in close contact with another infected person, Patient 9, became ill between 14 and 40 days after the funeral. The remaining 12 patients were in contact with at least one patient who had previously developed symptoms."
