𝐁𝐢𝐠 𝐫𝐞𝐦𝐢𝐧𝐝𝐞𝐫 #𝟏 – If you have COVID-19, you are most contagious 1-2 days 𝐵𝐸𝐹𝑂𝑅𝐸 you show symptoms and the 1-2 days AFTER.

𝐁𝐢𝐠 𝐫𝐞𝐦𝐢𝐧𝐝𝐞𝐫 #𝟐 – This highlights the importance of wearing a mask.

I cannot overstate the importance of these reminders. I’ve written already about how masks are safe (they don’t reduce your immune system, they don’t make you more likely to get sick, they aren’t signs of oppression or fear, and other myths) in several other posts. (I re-linked to those at the end – they contain more data than you probably want to know – but, it’s all there in case we are still arguing about their importance and effectiveness.)

Lastly, I do want to pray for our leaders. I pray for their recovery and also the recognition that we are all susceptible to COVID-19 – but not all susceptible to what happens after infection. It’s a privilege to have full access to testing, early diagnosis, and early treatments. And, I’m thankful for those – goodness, I work in global health and see first-hand the importance of these privileges. But, those are not equal.

These inequities are what I’ve anchored my career in – in fact, I’m going today to Capitol Hill (virtually) to advocate to our congressional leaders about the importance of providing healthcare to the most in need. I’ve done the same at the United Nations with my research and perhaps will write a post about that one day. I say this not to brag but to let you know that these posts are not political, simply opinions, or conjectures – although these are becoming harder and harder to write without some being interpreted that way and I’ve seen that increase in the past month. These are posts that are data-based from my expertise, training, and degrees.

Yes, there exists good and bad data and we can likely talk about that all day long. But, the point is – our expertise and training as epidemiologists and infectious disease specialists is to sift through the data, evaluate the good studies (harder said than done, hence the lengthy training), and build evidence-based conclusions for public health. Believe the majority of scientists on these issues. Wear a mask.
