Austin Peay to host special lecture on coronavirus

(Published Feb. 26, 2020)
As of Tuesday, Feb. 25, the COVID-19 coronavirus outbreak has infected about 80,000 people worldwide and killed 2,711.
Officials first detected the new virus 鈥 named SARS-CoV-2 鈥 in Wuhan City, China, late last year, and it has spread to 37 countries. The Centers for Disease Control and Prevention (CDC) on Tuesday warned Americans to begin preparations for clusters of infection in the United States.
Austin Peay State University will host a special lecture at 5:30 p.m. Tuesday, March 3, so area residents can learn more about the coronavirus outbreak, about similar viruses and about how outbreaks such as this one take root and spread.
Austin Peay medical laboratory sciences professor Jane Semler will deliver the presentation at the university鈥檚 monthly Science on Tap series at Clarksville鈥檚 Strawberry Alley Ale Works. The title of the talk is 鈥淐oronavirus: The Common Cold and its Sinister Cousins.鈥
鈥榃hat makes some coronaviruses more sinister?鈥

Coronaviruses are common and infect humans and other animals, according to the CDC. Common human varieties cause mild and moderate upper-respiratory tract illnesses such as the common cold.
鈥淐oronaviruses do cause the common cold, it鈥檚 a lower percentage than the rhinoviruses, which is the most common cause of the common cold, but 15-30% are due to coronaviruses,鈥 Semler said.
But the coronavirus that causes our colds should not be confused with the coronavirus that鈥檚 dominating the news, the CDC warns.
鈥淲ith the common cold, you have sneezing, runny nose, you feel a little tired, maybe a little fever, a sore throat,鈥 Semler said. 鈥淲hat鈥檚 different about this coronavirus infection? Well, people always have a fever, they have a cough. It progresses rapidly to shortness of breath. They have severe pneumonia, and it certainly can be fatal.鈥
During her lecture, Semler will discuss how the coronavirus and its cousins 鈥 such as the 2003 SARS outbreak that killed 774 people and the 2012 MERS outbreak that killed 858 people 鈥 enter cells and replicate.
鈥淲hat makes some coronaviruses more sinister than others?鈥 she said.
From wild animals to humans
She鈥檒l also discuss how such viruses originate in wild animals before jumping to domesticated animals and humans and how the viruses spread from human to human, causing outbreaks, epidemics and pandemics (in this case mostly via coughs and sneezes).
鈥淚t was reported that 66% of the victims in the initial cases had contact with the Huanan Seafood Wholesale Market in Wuhan, China,鈥 Semler said. 鈥淚t seems that probably some wild animal that was being sold at that market is implicated.鈥
The CDC reports the current virus, the 2003 SARS virus and the 2012 MERS virus all originated in bats, for example.
Semler also will discuss how officials test for the virus. The Tennessee Department of Health laboratory has CDC-developed test kits for the virus, she said.
鈥淚f any new cases or suspected cases come about, the sample will be sent to Nashville, and they will perform the testing,鈥 she said.
About Science on Tap
Austin Peay scientists explore a different topic the first Tuesday of every month at Science on Tap. Last month, Dr. Mollie Cashner explored the weird, wonderful world of animal sex.
Science on Tap is sponsored by the APSU College of STEM.
