Ferret study shows SARS-CoV-2 airborne transmission dynamics
A team of researchers led by Sander Herfst from Erasmus University Medical Center in The Netherlands suggests severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could spread through the air at a one-meter distance and cause infection in a new ferret model study.
They also found the SARS-CoV-2 can be dispersed through ferret fur, indicating a brand-new mode of transmission.

An inoculated donor ferret is housed in the bottom cage and the next day, an indirect recipient ferret is added to the top cage. The cages are connected through a hard duct system consisting of four 90° turns. The system is built of several horizontal and vertical 15 cm wide PVC pipes that allow upward airflow from the donor to the indirect recipient animal. The average length of the duct system is 118 cm with the shortest and longest length 73 and 163

Where did it come from? More than a year later, nobody knows for sure. But a new report may soon shed light on the origins of the coronavirus that has wreaked havoc across the world, killing more than 2.6 million people, including around 530,000 in the United States.
A World Health Organization team has been looking into how the virus, SARS-CoV-2, emerged, and their report is expected to be issued this month. Several experts from the team, speaking at a forum Wednesday, indicated that the report will say the most likely scenario was that the virus jumped from animals to humans, leading to the first known outbreak at a seafood market in Wuhan, China.
