How can someone be positive but asymptomatic, and someone else is absolutely wrecked for > a month?

Age and fitness are the main factors. I had 20 guys on my XC test positive but none had any symptoms. Very few children get symptoms while many old people die from it.

Because science

COVID 19 is a vascular virus. It can directly attack the blood vessels in your body. That gives the virus many different avenues to cause problems in your body. Once COVID 19 starts replicating inside your body, where it goes, nobody knows.

By contrast, the flu is a respiratory virus. It will primarily attack your respiratory system and has much more consistent symptoms and course of infection.

Asymptomatic COVID 19 occurs when your body's immune response is able to put up enough of a defense to keep the virus from getting a enough of a hold in your vascular system. We really do not know whether viral load makes a difference in whether COVID 19 is asymptomatic. There are studies going both ways. We do not know whether innate immunity is key or some sort of T cell immunity from common cold infection makes a difference or whether some people just get lucky.

Yeah pretty crazy. A friend of mine who is an avid marathoner ~40 years old and very healthy was totally out of commission for about a month with covid. His wife got it, she is less healthy, and basically just had the sniffles. So weird.

Legit honest discussion here. Love it.

At least some of it has to do with how many ACE2 receptors you have in your lungs and whether you suffer from hypertension.

Of course it depends how your immune system responds to infection

(nitpick: people are like: "i have a strong immune system - i hardly got any symptoms!" when in reality it's the other way around)

Multi-organ involvement

Opportunistic bacterial infection

Some people are weaklings. Some people aren’t

I contracted COVID in the last third of November.

46 YO

45 MPW

In the last twelve years I’ve had the flu once.

I was in 17:00 5K and 29:00 8K shape when I got COVID. I was really sick for 5 days with a high fever profuse sweating, and mind splitting headaches. After a week I felt pretty good but still had a lingering wet cough for a week and a half. I also lost a fair amount of muscle mass in just a week. After six weeks off I resumed running and it’s like starting all over again. My HR gets into the high 180s after two miles @8:30 pace which is the same as the last mile of a five mile 5:55 pace run.

I’ll keep updating this recovery.

Why do you think thst the loss of smell and taste is spooky? Thats what normally happens with the common cold or flu.

Who are these people who know all sorts of people who have had Covid?

Nobody I know or work with has had it

When you are 46 years old and take off six weeks of running for any reason you lose a tremendous amount of conditioning.

When you are 20 and miss a week or two you lose almost nothing.

By mid 30s, if i missed a week it took a month to get back to where I was.

I missed 4 months with a knee issue and it took 2 years to get back

Some of us are strong and some of you are weak.

Idk why can I run sub 15 5k while you can’t even break a 6 min mile? Why are some people allergic to peanuts but others eat them everyday? Why are some people 5’ and others 7’. Everyone is built different how do you not understand this?

Funny but true. Immunity works by being exposed to and defeating a wide variety of pathogens.

The people getting the worst of the bug are likely the ones who've been relatively isolated and not taking care of their health otherwise.

Isolating everyone from each other further is going to cause real problems, as everyone will end up with weaker immune systems.

This is a main reason the illness is so different in people. It apparently also depends a lot on the initial viral load that infected you. Your own body’s immune response to it doesn’t help.

I’m late 30s, very fit, healthy, no vitamin D deficiency, etc. Didn't get a fever, never most my sense of smell, never had a dry cough.

This was still worse than a bad flu for me. My running was affected for many months afterwards.

What are your levels for Vit D ?
