0:00.0	This is Dan McCollum from Augusta University.
0:02.9	Trying to give you a little bit of basic information about the most recent pandemic of COVID-19.
0:09.3	I want to say a couple of things before I even get started.
0:12.1	This pandemic is evolving on a day-by-day basis.
0:14.7	This was recorded on March the 29th, and it will be immediately out of date as soon as I publish it.
0:19.9	Use multiple resources, stay informed, and follow your institution's local guidelines when caring for patients.
0:24.6	This recording represents my views and no one else's, including my institutions.
0:28.6	Also apologies for the audio quality of this as I'm having to record this in another location due to social isolation.
0:35.6	So let's start off with what this pandemic is. So the
0:40.2	virus itself is named SARS-CoV-2. It's an RNA virus that's part of the family of coronaviruses.
0:45.5	This family includes four viruses that are widely distributed and cause symptoms
0:50.1	similar to the common cold. Two serious viral epidemics with high mortality are also
0:55.1	caused by members of this viral family, SARS and MERS. This new virus is most closely related
1:01.6	to the SARS virus. Technically, the virus is called SARS-CoV-2 and the illness that it causes
1:07.7	is COVID-19. I'll just call the disease and the virus COVID to make this
1:12.9	simpler during this podcast. The virus incubates for up to 14 days with the median incubation
1:18.6	period of four days. Patients become sicker approximately 7 to 10 days after exposure, but this is
1:24.5	highly variable. Approximately 80% of patients have only mild symptoms
1:28.6	similar to a typical case of influenza, or can even be asymptomatic with no symptoms at all.
1:34.9	The data isn't very clear on how long a patient could be contagious after contracting the disease.
1:39.8	Repeat testing for virus may be positive for weeks, but it's not clear how contagious the patient
1:44.4	is more than eight days after recovery.
