A routine public health report from the United States describes cases of arboviral diseases that occurred in 2022. These are illnesses spread by mosquitoes and ticks, such as West Nile virus, dengue, and Powassan virus. The report's purpose is to track and document these cases for health officials.
The report does not provide specific numbers on how many people were sick or where they lived. It does not compare this year to past years or explain why cases might have happened. It is a basic description of the cases that were reported to health authorities.
This is not a new research study. It is a standard surveillance update. Readers should not draw any conclusions about personal risk, new outbreaks, or changes in disease patterns from this report alone. For information on preventing mosquito and tick bites, people should consult their local health department or the CDC.
