Dr. Rizwan Sohail is an infectious disease specialist based at the Mayo Clinic, where he holds a joint appointment with the divisions of Infectious Diseases and Cardiovascular Diseases.

He completed his internship and residency in internal medicine at Michael Reese Hospital in Chicago and then a Fellowship in infectious diseases at the Mayo Clinic.

In This Episode We Discuss

Distinguishing between COVID-19 (disease) and the actual novel coronavirus (SARS-CoV2)
What is different about this specific coronavirus compared to others
This coronavirus has a respiratory droplet transmission
The difference between respiratory droplet and airbourne transmission
Time from exposure to SARS-CoV-2 to symptom
The disease mechanism
Current case reports on those hospitalized
In those who have recovered, do we know yet whether they can be reinfected or if they have established immunity?
Is the severity of the disease impacted by the length or magnitude of the exposure?
On average, for someone infected how many people will they likely infect.
How it compares to other viruses in terms of lethality and transmissibility
Why social distancing (and potentially self- isolation) is so important
Impact on healthcare system
Mortality rate is not inherent to the virus alone, but mediated by how the healthcare system holds up, as well as population demographics, etc.
Response needed now: a) public health/governmental; b) individuals (context dependent)

0:00.0	Hello, everyone. You are listening to Sigma Nutrition Radio. I'm your host, Danny Lennon.
0:06.0	This is episode 323 of the podcast, and this is a relatively time-sensitive episode.
0:16.0	And as you will know by the title of this, and just by the fact that this is something that is
0:22.5	gripping the world right now and influencing all of us in various ways, this is an attempt
0:31.1	to cover over some of the accurate information relating to the SARS-CoV-2 virus and then the establishment of
0:40.8	COVID-19 disease in those infected.

1:21.2	established expert in the area of infectious diseases. There's no shortage of information going around,
1:29.2	and I'm sure many of you have been consuming
1:32.7	an incredible amount of that.
1:34.4	And so hopefully this doesn't add to an overwhelm

1:42.1	So hopefully something within here is useful. I'm going to be talking to
1:46.7	Dr. Riswan Sohal of the Mayo Clinic, and he is an infectious disease specialist based at Mayo Clinic,
1:56.0	where he holds a joint appointment with the divisions of infectious diseases and cardiovascular diseases.
2:02.6	His internship and residency programs internal medicine were done at Michael Rees Hospital in Chicago
2:09.6	and then he followed up with a fellowship in infectious diseases at the Mayo Clinic
2:14.6	and has been working in that field since about 2002.
