What We Know So Far About COVID-19 Transmission

Many of us woke up to the shocking news that the President Donald Trump and first lady Melania Trump have tested positive for coronavirus. This is an important reminder for all of us about how quickly and quietly the virus can spread from one person to another.

Here’s what we know so far about COVID-19 transmission.

When are people most contagious?

According to the latest evidence, people most commonly spread the virus to each other 2-3 days before symptoms start. Most people seem to be most contagious 1-2 days before they become sick. Scientists think that the “viral burden” — how much virus you have replicating inside your body with the ability to spread to others — is linked to the severity of your symptoms.


How COVID-19 Affects Your Body

But this is still being worked out because some people never develop symptoms but are still contagious at some point during their infection.

Once someone is infected, it can be 5-6 days before symptoms start, though some people may not start feeling sick until 14 days after they were exposed (and some don’t end up feeling sick at all).

What’s the most common way that the virus spreads?

Transmission through infected droplets appears to be the most common way that the virus spreads. Respiratory droplets are usually heavy droplets that are released when someone coughs or sneezes. This is where the “6-feet rule” comes from, because these droplets generally fall out of the air within 6 feet.

More and more research, however, is pointing to droplets as a continuum — with smaller droplets, called aerosols, released just by talking or breathing. The louder you talk or sing, the farther they may float. Because aerosols are much smaller, they can stay suspended in the air for a longer period of time and travel farther. So 6 feet in a poorly ventilated space may not be enough distance to protect you.

An interesting “real-life experiment” was recently published showing what happened to travelers on two buses carrying passengers to a ceremony in China. One bus carried an infected person, while another had no infected people. This was early in the pandemic, so no one was wearing a mask. Over 1/3 of the people on the bus with the infected person caught the virus, while no one on the other bus caught it. It didn’t matter how far people were sitting. Even people sitting very far away from the infected person caught the virus.

What can we do to prevent the spread? 

Based on what we know so far, it’s important to avoid the 3 C’s to help prevent transmission.

  • Closed spaces with poor ventilation
  • Crowded places with people nearby
  • Close-contact situations

As we head into cooler months with more time spent indoors, it’s really important to keep these in mind. Avoid the 3 C’s, and wear masks in all situations when you are around other people outside of your household.

We are fortunate that the president’s infection was identified early and that he has the best health care available to help him through his recovery. This is a lesson to all of us to remain vigilant to help prevent the spread of COVID-19.

How To Make Kale the African African-Style Way

First, place kale in a large bowl of water with a half a teaspoon of salt to loosen dirt or debris.
Drain and rinse kale in a colander. Prep kale by removing the stems and tearing them into 2-inch pieces.

If your kale is tender then it is okay to keep the stems for added fiber and chop the kale in 1-inch pieces.

Saute onion in olive oil until soft, add tomatoes and saute until soft. Stir in kale and cook until
