COVID-19 RESULTS BRIEFING

COVID-19 Results Briefing

Brazil

January 14, 2021

This document contains summary information on the latest projections from the IHME model on COVID-19 in Brazil. The model was run on January 13, 2021 with data through January 11, 2021.

Current situation

• Daily reported cases in the last week increased to 53,100 per day on average compared to 35,600 the week before (Figure 1). • Daily deaths in the last week increased to 800 per day on average compared to 740 the week before (Figure 2). This makes COVID-19 the number 1 cause of death in Brazil this week (Table 1). • Effective R, computed using cases, hospitalizations, and deaths, is greater than 1 in 6 states (Figure 3). • We estimated that 30% of people in Brazil have been infected as of January 11 (Figure 4). • The daily death rate is greater than 4 per million in Amapá, Amazonas, Espírito Santo, do Sul, Paraná, , do Sul, Rondônia, and (Figure 6).

Trends in drivers of transmission

• In the last week, no new mandates have been imposed. No mandates have been lifted this week (Table 2). • Mobility last week was 18% lower than the pre-COVID-19 baseline (Figure 8). Mobility was near baseline (within 10%) in in 12 states. Mobility was lower than 30% of baseline in no locations. • As of January 11 we estimated that 60% of people always wore a mask when leaving their home compared to 60% last week (Figure 9). Mask use was lower than 50% in Maranhão, and . • There were 43 diagnostic tests per 100,000 people on January 11 (Figure 10). • In Brazil 65.8% of people say they would accept a vaccine for COVID-19 and 21.2% say they are unsure if they would accept one. The fraction of the population who are open to receiving a COVID-19 vaccine ranges from 86% in Maranhão to 88% in Distrito Federal (Figure 12). • We expect that 68 million people will be vaccinated by May 1 (Figure 13). With faster scale-up, the number vaccinated could reach 76 million people.

Projections

• In our reference scenario, which represents what we think is most likely to happen, our model projects 255,000 cumulative deaths on May 1, 2021. This represents 52,000 additional deaths from January 11 to May 1 (Figure 14). Daily deaths will peak at 900 on January 23, 2021 (Figure 15). • By May 1, 2021, we project that 3,600 lives will be saved by the projected vaccine rollout. If rapid rollout of vaccine is achieved, 7,900 lives will be saved compared to a no vaccine scenario. As compared to a no vaccine scenario, rapid rollout targeting high-risk individuals only could save 9,700 lives (Figure 14). • If universal mask coverage (95%) were attained in the next week, our model projects 16,000 fewer cumulative deaths compared to the reference scenario on May 1, 2021 (Figure 14). • Under our mandates easing scenario, our model projects 259,000 cumulative deaths on May 1, 2021 (Figure 14). • We estimate that 42.1% of people will still be susceptible on May 1, 2021 (Figure 17). • The reference scenario assumes that 7 states will re-impose mandates by May 1, 2021 (Figure 18).

covid19.healthdata.org 1 Institute for Health Metrics and Evaluation Brazil COVID-19 RESULTS BRIEFING

• Figure 21 compares our reference scenario forecasts to other publicly archived models. Forecasts are widely divergent. • At some point from January through May 1, 18 states will have high or extreme stress on hospital beds (Figure 22). At some point from January through May 1, 27 states will have high or extreme stress on ICU capacity (Figure 23).

Model updates

Methods have not been changed in this week’s update. Reported data on vaccination scale-up for select countries has led us to revise the expected rates of vaccination. For some countries, the revision has reduced the expected vaccination rates, and for others – such as Israel – the revision has increased expected vaccination rates.

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.

Projections and scenarios

We produce six scenarios when projecting COVID-19. The reference scenario is our forecast of what we think is most likely to happen. We assume that if the daily mortality rate from COVID-19 reaches 8 per million, social distancing (SD) mandates will be re-imposed. The mandate easing scenario is what would happen if governments continue to ease social distancing mandates with no re-imposition. The universal mask mandate scenario is what would happen if mask use increased immediately to 95% and social distancing mandates were re-imposed at 8 deaths per million. These three scenarios assume our reference vaccine delivery scale up where vaccine delivery will scale to full capacity over 90 days. The rapid vaccine rollout scenario assumes that vaccine distribution will scale up to full delivery capacity in half the time as the reference delivery scenario and that the maximum doses that can be delivered per day is twice as much as the reference delivery scenario. The rapid vaccine rollout to high-risk populations scenario is the same but high-risk populations are vaccinated before essential workers or other adults. The no vaccine scenario is the same as our reference scenario but with no vaccine use.
