“A classic droplet is one that if I were here and I was six … “You’re not a living organism, so you’re completely dependent on having access to what we call a ‘susceptible’ cell, or one that can be infected and support your replication.” Even if a human breathes some amount of virus in—or rubs some in her eyes, or licks some off her fingers—that doesn’t always happen. The problem with getting a COVID-19 test too soon after exposure is that it can produce a false-negative result. She points out that 80% of transmissions are due to 20% of COVID-19 patients. What does it mean to be “exposed” to a virus? Newscasts and social media are alive these days with images of frontline medical workers receiving much-needed COVID-19 vaccines. If you get tested because you have symptoms or were potentially exposed to the virus, you should stay away from others pending test results and follow the advice of your health care provider or a public health professional. Typically, it takes at least a few days for the virus to show up in your system.

Before this stage, the number of viruses in a person’s system (their “viral load”) is likely too low to be detected by a test. And the likelihood of that happening is directly linked to how far you were from that person and whether you had taken measures to protect yourself. “It’s not really well understood if those individuals are potentially replicating virus to high levels, whether they’re infected for longer periods of time in comparison to symptomatic people,” Pitzer says. It’s about the physics of those actions—the propulsive air is necessary. “What’s more informative is if you truly self-quarantined for 10 days,” Lee says. This first period, where a virus is gathering materials for replication, then creating initial copies of itself and releasing those copies to infect cells on either side, is known in some virology circles as a “latent period.” It’s a given amount of time where a virus is busy finding accessible, permissive cells and setting up infrastructure to replicate itself and is therefore undetectable. After gathering proteins to build a template of itself, it then hijacks every possible process in that cell—the processes that make it a liver cell, say, or a lung cell—and turns it into a virus factory. “When it enters the cell, it kind of disrobes,” Messaoudi says, releasing its genetic material, called RNA. What happens if my COVID-19 at home test results come back positive? The three experts interviewed for this article recommended getting tested twice, which allows for the inherent variability in viral load and in everyone’s immune systems, and for false negatives. Asymptomatic infection is an area of continued debate among virologists. You probably know this much already. These are all ways to potentially get virus on yourself,” says Yale University epidemiologist Virginia Pitzer. Your muscles and bones are just “innocent bystanders” in this effort. Let’s say you’ve been exposed to COVID-19. “Polymerase is like the big piece, and the tiny piece it latches onto is the primer. Lee argues that asymptomatic people don’t necessarily shed less virus than symptomatic people. An artist rendering of SARS-CoV-2 virus particles. Syphilis Window Period: 3-6 weeks in general; but, most resources recommend getting tested 90 days after exposure. You can also shed virus through now-much-discussed “aerosols,” tiny droplets that fly out of your mouth when you breathe or speak. Most available COVID-19 tests are PCR or “polymerase chain reaction” tests. That’s not always a given. For the two to fuse, and the virus to access the cell, a special enzyme must be present at the site to help the process along. How Long After Exposure Do You Get Coronavirus? There’s another essential part to PCR tests that plays in here, as well: the “primers,” or short strands of genetic material added to a testing solution to help define which part of the virus’s RNA will be emphasized for replication. How Long Does It Take for Trichomoniasis to Show Up? (The new, more transmissible SARS-CoV-2 variant out of the U.K. may owe some of its advantage to differences in its spike proteins that make it particularly effective at binding to ACE2, and thus at entering cells.)
