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.https://www.ajog.org/article/S0002-9378(20)32573-4/fulltext …

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).1 reply 3 retweets 8 likesShow this thread -
The adjusted case fatality rate for pregnant women was 1.3% overall, but rose to 2.1% and 5.9% for those aged 35 to 39 years and 40 to 44 years, respectively.pic.twitter.com/0MhShSpcTf

Pregnant women w COVID consistently had a higher risk of death than nonpregnant women of similar age with COVID-19 (adjusted RR, 1.68; 95% CI, 1.36–2.08). The risk of death was elevated for both younger and older pregnant women.pic.twitter.com/Pk6J3wMsYb

Overall 8.7% of COVID-confirmed pregnant women had pneumonia, ranging from 7% in the youngest to 18% in the oldest group. Only a about 5% of non-pregnant women ended up with pneumonia. Pregnant women have twice the risk of severe disease [aRR (95% CI): 1.97 (1.82 , 2.13)].pic.twitter.com/NODdi3MPiU

Although the absolute risk of pneumonia was highest among older pregnant women, the highest *increased risk* (RRs) relative to non-pregnant people appeared among both younger and older pregnant women.pic.twitter.com/tlHvFcqD7V

It's been repeatedly suggested to me that "pregnant women are young" and thus "age isn't a factor". But both young and old age confer risks in pregnancy. And our work suggests that the combination of COVID + pregnancy increases risks for both younger and older women.

@GidMK can comment on age-specific CFRs among people age <45. Is there enough data to understand how risk changes from age 15 to 45?1 reply 0 retweets 0 likesShow this thread
I think for this age group we have pretty good and consistent data that the risk increases exponentially by age in usualy circumstances - that's certainly what we and others found. Interesting to see that the risk of severe disease is different in pregnancy
