South Korea’s public health authorities have confirmed that the “water tanks of portable toilets” were the reason behind an outbreak of norovirus at the host city of the PyeongChang Winter Olympics that affected around 300 security personnel for the event last month.
The authorities announced Sunday that the water tanks of mobile toilets were what caused the norovirus infection as a result of its epidemiological investigation of Horeb Youth Camp Center and other related facilities. According to the investigation, the genotype of the virus detected in water tanks was matched with those of patients. There had been around 570 portable lavatories set up during the Olympic period and ironically, water used to wash hands or brush teeth before leaving a toilet for the sake of hygiene was the culprit of infection.
Water tanks had contained underground water from the Gangwon region. It is likely that the toilets’ water tanks and septic tanks had not been properly separated, according to the authorities. Norovirus is usually spread through water contaminated with the feces of the infected.
