I’ve been taking an online course at MIT that goes into great detail about the transmission of COVID-19, and I’d like to share a few things I’ve learned with everyone here who cares to read this.
Obviously, it is safest to not meet with anyone during this pandemic, especially now that many hospitals are at or near capacity. However, human nature being what it is, that is not realistic to expect.
So if you decide to meet another person, take steps to be as safe as possible. If you have lived in complete isolation from others for at least 10 days or more, you are probably ok. If you both tested negative and have not encountered anyone since taking the test, you are probably ok - but tests are not 100% accurate, remember that. Being asymptomatic is not sufficient, as 40 to 80 percent of cases are asymptomatic and contagious.
Aerosols are a primary mode of transmission. Assuming you are wearing a mask, physical distancing has a small effect in closed rooms, as aerosols tend to mix well in the room and are distributed more or less evenly.
Here are some tips.
Wear an N95 or better mask, if you can get one, and have your partner do the same. Assuming you’re BOTH wearing the SAME grade of masks, the effective reduction in virus transmission rate is about 10x for a single layer cotton mask, 100x for a triple layer surgical mask, and 1000x for an N95. Make sure it fits well. It can be uncomfortable, but your respiration rate will be low if you’re lying down cuddling, so it’s not that bad.
Increase outdoor air ventilation through the room. If you can cuddle outside, do so. If not, crack a window - the more fresh air exchange the better. This helps to prevent the build up of contagious aerosols in the room. If you can, maintain 60-80% relative humidity in the room, that kills the airborne virus the fastest.
Don’t talk too loudly. Your production rate of aerosols increases when you increase your volume, so remain quiet, speak softly or whisper.
Limit your exposure time. This is more of a factor indoors, as aerosol concentration increases in a room over time.
Change into pajamas or your choice of cuddling clothes before cuddling. Change out of them after, so you’re not wearing potentially contaminated clothing for the rest of the day. The same goes for sheets or blankets that were used. Wash the cuddling clothes after.
I’m only part way through the course, so I’ll provide more tips if I learn more worth sharing.
