Study locations and locations for related viruses from study of bat reovirus as cause of acute respiratory disease and encephalitis in humans, Bangladesh, 2022–2023. Inset shows Bangladesh with color-coded locations of patients (BDB040, BDB052, BDB047, BDB113, and BDB051) from whom we detected Pteropine orthoreovirus in archived throat swab samples. Larger map shows global locations from which related viruses have been detected in humans, bats, and monkeys.
