You can ask people when they first noticed symptoms after being exposed to someone with Covid-19, assuming that the exposure was obvious. One to two days tends to be time it takes for the immune system to recognize that there’s been a mass release of respiratory viruses and to generate reactions that will cause symptoms.īy contrast, it’s been easier to measure the typical length of the incubation period. Therefore, many infectious disease experts have been assuming that the latent period is at least 48 hours shorter than the incubation period. Doing such a study would then require a whole lot of cotton swabs and a whole lot of discomfort.

After all, asking a person, “when did you first start shedding virus” can be like asking, “when did you first start having noticeable body odor” or “when did you start becoming annoying?” The person most likely wouldn’t be able to tell you that “it was 12:35 pm when virus started coming out of my mouth like from a sprinkler” or “it was 12:35 pm when sewage and I became a lot less different.” The only direct way to tell when a person becomes contagious is to test that person continuously, like every minute or so. It can be challenging to figure out the typical length of the latent period. Symptomatic period: This is the time from the end of the incubation period when you first start having symptoms to when your symptoms resolve.During this time, you will have an infectious personality but in a bad way and can spread the virus to others. Infectious or contagious period: This is the time from the end of the latency period when you first become contagious until you are no longer contagious.Consider this the amount of time that it takes for enough of the virus to build up in your body and your immune system to wonder, in the words of Marvin Gaye, “what’s going on” and react. Incubation period: This is the period of time between getting infected with the virus and first developing symptoms.Think of it as the time it takes for the virus to get a foothold (or maybe a spikehold) in your body, to do the nasty in your body, and make enough copies of itself. Latent period: This is the period of time between getting infected with the virus and first becoming contagious.

Why? Well, keep in mind four key periods: When it comes to developing symptoms of Covid-19, the key durations to remember are two days, five to six days, and 14 days. The answers will tell you how long you should remain concerned that you may have been infected and will help you better understand the bases of the recommended quarantine durations.

It’s a common set of questions because the Covid-19 coronavirus has been spreading so widely in the U.S., and who hasn’t been to a “dress up like a marmot” event recently.
