Rheumatic fever (RF) and its valvular sequela rheumatic heart disease (RHD) have been a scourge on humanity for ages, and it is only relatively recently that high-income countries have seen rates of RF decline dramatically. Yet, the Global Burden of Disease Study estimates that more than 275,000 deaths due to RHD still occur every year around the world, especially in low and middle-income countries including Brazil.

In this issue of the journal, Figueiredo et al. have presented ambitious modeling of the disease burden and costs of RF and RHD in Brazil. Using data from the Hospital Information System of Brazil, their central findings are that mortality rates for RF and RHD have increased by 215% and 42.5% respectively from 1998 to 2016. Additionally, the estimated cost for procedures related to RF/RHD diagnosis, interventions such as valve surgery, and hospitalizations for RHD complications like stroke and endocarditis was nearly $27 million USD in 2019.
