Coronavirus shown to spread in high heat and humidityBy Dr. Liji Thomas, MDMar 30 2020
A new study explores the possibility that the novel coronavirus, which is ravaging the world, can spread in hot and humid conditions, dispelling the view held by some investigators that the virus is more easily transmissible in colder climates.
The study published in the JAMA Network Open examines the possibility that the virus could have been spread by one infected person to 8 other people and showed no signs of weakening in warm and humid conditions. All nine people having used or worked at the same indoor public bath center....
The study
The study centered on nine people from Huai’an city, 700 km northeast of Wuhan, in Jiangsu province, China, who were admitted to hospital between January 25, 2020, to February 10, 2020. Testing for SARS-CoV-2 was undertaken by performing quantitative reverse-transcription polymerase chain reaction (QRT-PCR) on samples from throat swabs collected from all patients. Computed tomography (CT) and blood examinations were also carried out to confirm the diagnosis.
The findings
The bath center had a swimming pool, showers, and sauna, with an area of about 300 square meters, 60% humidity, and a temperature between 25 ?C and 41 ?C. The index patient had visited Wuhan, and on his return showered at the bath center on January 18, 2020. The next day he developed a fever. He was confirmed to be COVID-19 positive on January 25, 2020.
The next seven patients had all used one of the facilities in the same center between January 19 and 24. All developed symptoms 6-9 days later. The last patient was working in the center and became symptomatic on January 30. All the patients were young, about 35 years old, on average.
The infection was confirmed by qRT-PCR in all cases. The other investigations supported the diagnosis. None of the patients required ventilatory support....https://www.news-medical.net/news/20...-humidity.aspx
