We are living through a pandemic. A couple of people on the team have fallen ill with Covid-19, some recovering quickly, some suffering very unpleasant long-term effects.

There are a couple of easy and safe things you can do to protect yourself and your loved ones from getting sick or developing complications:

FFP2 Masks

Getting sick with Covid-19 is not a binary option. As with most infectious agents, initial viral load matters a lot for the severity of the disease and possible complications.

Normal surgical masks can protect others. However, since Covid-19 is provably aerosol-transmittable, they won't lower the viral load significantly for you.

The best way to protect yourself is to wear FFP2 masks in all closed spaces (especially small crowded ones, like public transportation), because they can filter aerosols.

Most of the FFP2 masks are very uncomfortable for wearing and breathing, so you won't really use them. Some don't fit well and are therefore ineffective. That's why I recommend the masks of this type — they are as easy and convenient to use as normal surgical masks:

Vitamin D

There is sufficient evidence that:

  1. Vitamin D deficiency correlates with the severity of Covid-19 complications (many studies, easily googlable). A recent study (Jan 2021) also found that Autumn COVID-19 surge dates in Europe correlated to latitudes, not to temperature-humidity, pointing to vitamin D as contributing factor.

  2. Vitamin D interventions at early stages can significantly improve the course of the disease (here is a great analysis of a recent clinical randomized controlled trial).

In Europe, most people suffer Vitamin D deficiency in Winter and supplements are widely suggested by healthcare experts. I highly recommend everyone on the team to get tested and take Vitamin D3 supplements. In the EU and the US, a home test kit can be ordered online. The company will cover the costs.
