Our new work is out in @GlobalHealthBMJ today. This is the work of dozens of teams across 12 countries. Here we show the clear excess risk associated with COVID-19 in pregnancy. Here’s what we found and how we did it.🧵

gh.bmj.com/cgi/content/fu… @GlobalHealthBMJ Yes, there are many studies about COVID in pregnancy. But this individual patient data meta-analysis tries to address some limitations & heterogeneity between previously published work. Plus, we include unpublished & re-analyzed data, including substantial data from LMICs. 2/x

Happy to share our work @AJOG_thegray on clinical risk factors for adverse outcomes among women w COVID-19 in pregnancy & postpartum. We uniformly analyzed data from 33 countries/territories🌍, including 21,977 cases of SARS-CoV-2 infection.🧵
ajog.org/article/S0002-… @AJOG_thegray Similar to the general population, pregnant people with COVID-19 and comorbidities like diabetes, hypertension, & cardiovascular disease are at increased risk for worse COVID outcomes & and worse pregnancy outcomes.

A few initial thoughts on the updated CDC “Community Levels” guidance.

Some good things here.
Some bad things.
Some points lack clarity or transparency.

cdc.gov/coronavirus/20… The good things!

•A data-driven approach to turning policies on & off
•Additional indicators incorporated into the framework
•Emphasis on layered protections

Given recent WHO interim vaccine recs in pregnancy, I want to share our new work @AJOG_thegray. Pregnant people are *TWICE* as likely to develop severe disease & have a 60% higher risk of death when it comes to #COVID19 as compared to non-pregnant women. ajog.org/article/S0002-… This is the largest & longest running effort yet to characterize COVID risk in pregnancy based on epidemiologic surveillance system of viral respiratory diseases of Mexico (475 monitoring hospitals in the Mexican Public Health Network). (Thanks to @Raigam_Martinez & colleagues).

Adding to the strangeness of 2020, I've now written a letter to the editors with concerns about a study that hasn't even been published! But scientists have to adapt to the current #Covid_19 context, right? So, here's what we have to say and why.🧵

The Danish mask study is registered & protocol paper is published, but I haven't seen the results. The study randomized people to get a box of free face masks + messages about wearing masks for 1 month. I actually think it's a great idea to test this approach. 2/x

Summer is here! We’re ready to get out of the house. But what's safe? Here's a great @NPR article from @AubreyNPR @laurelwamsley @cwroth on how experts think about the risks.

And you can evaluate your own risk by considering these 5 things. (1/x)

npr.org/sections/healt… PEOPLE. Who are you spending time with and how many of them are there?

Meeting with one other person who has stayed home for the past two months is lower risk. Meeting with ten people who have high-risk jobs is higher risk.

You’ve probably seen or heard about the #PlandemicDocumentary video. It reaches many conclusions that have zero scientific support and are dangerous because they could harm your health. Here are rebuttals and references to just a few of the false claims. A thread. (1/x) False claim #1: The novel #coronavirus was lab-made.

Truth: Genetic science allows us to understand how and when viruses emerge. Analyses by trusted scientists clearly demonstrates that the virus occurred naturally. (2/x)
