Brazil COVID-19 RESULTS BRIEFING COVID-19 Results Briefing Brazil March 17, 2021 This document contains summary information on the latest projections from the IHME model on COVID-19 in Brazil. The model was run on March 17, 2021 with data through March 15, 2021. Current situation • Daily reported cases in the last week increased to 62,400 per day on average compared to 57,900 the week before (Figure 1). • Daily deaths in the last week increased to 1,900 per day on average compared to 1,600 the week before (Figure 2). This makes COVID-19 the number 1 cause of death in Brazil this week (Table 1). • The daily death rate is greater than 4 per million in 25 states (Figure 3). • We estimated that 38% of people in Brazil have been infected as of March 15 (Figure 4). • Effective R, computed using cases, hospitalizations, and deaths, is greater than 1 in 19 states (Figure 5). Trends in drivers of transmission • Mobility last week was 26% lower than the pre-COVID-19 baseline (Figure 9). Mobility was near baseline (within 10%) in Acre, Amapá, and Pará. Mobility was lower than 30% of baseline in Bahia, Ceará, Paraná, Pernambuco, Piaui, Rio Grande do Norte, Rio Grande do Sul, and Roraima. • As of March 15 we estimated that 66% of people always wore a mask when leaving their home compared to 65% last week (Figure 11). Mask use was lower than 50% in no states. • There were 54 diagnostic tests per 100,000 people on March 15 (Figure 13). • In Brazil 88.5% of people say they would accept or would probably accept a vaccine for COVID-19. The fraction of the population who are open to receiving a COVID-19 vaccine ranges from 81% in Roraima to 92% in Piaui (Figure 16). • In our current reference scenario, we expect that 101.88 million will be vaccinated by June 1st (Figure 17). Projections • If universal mask coverage (95%) were attained in the next week, our model projects 20,000 fewer cumulative deaths compared to the reference scenario on July 1, 2021 (Figure 18). • Under our worse scenario, our model projects 427,000 cumulative deaths on July 1, 2021 (Figure 18). • In our reference scenario, which represents what we think is most likely to happen, our model projects 389,000 cumulative deaths on July 1, 2021. This represents 108,000 additional deaths from March 15 to July 1 (Figure 18). Daily deaths will peak at 2,350 on March 27, 2021 (Figure 19). • By July 1, we project that 26,100 lives will be saved by the projected vaccine rollout. • Figure 21 compares our reference scenario forecasts to other publicly archived models. Forecasts are widely divergent. • At some point from March through July 1, 15 states will have high or extreme stress on hospital beds (Figure 24). At some point from March through July 1, 22 states will have high or extreme stress on ICU capacity (Figure 23). covid19.healthdata.org 1 Institute for Health Metrics and Evaluation Brazil COVID-19 RESULTS BRIEFING Model updates There are no major updates in the model this week. covid19.healthdata.org 2 Institute for Health Metrics and Evaluation Brazil COVID-19 RESULTS BRIEFING Figure 1.

Mean effective R on March 04, 2021. The estimate of effective R is based on the combined analysis of deaths, case reporting, and hospitalizations where available. Current reported cases reflect infections 11-13 days prior, so estimates of effective R can only be made for the recent past. Effective R less than 1 means that transmission should decline, all other things being held the same. <0.88 0.88−0.9 0.91−0.93 0.94−0.96 0.97−0.99 1−1.02 1.03−1.05 1.06−1.08 1.09−1.11 >=1.12 covid19.healthdata.org 6 Institute for Health Metrics and Evaluation Brazil COVID-19 RESULTS BRIEFING Figure 6.
