This represents about 11 million more cases in 2023 compared to 2022, and nearly the same number of deaths. Approximately 95% of the deaths occurred in the WHO African Region, where many at risk still lack access to the services they need to prevent, detect and treat the disease.

To better understand the extent of human-to-human transmission among health care workers, by estimating the secondary infection rate1 for health care worker contacts at an individual level.
To characterize the range of clinical presentation of infection and the risk factors for infection among health care workers.
To evaluate effectiveness of infection prevention and control measures among health care workers
