The Outlook features information on the relationship between hurricanes and dengue, a viral disease spread to people through the bite of infected Aedes species mosquitoes. Mosquito populations commonly decrease during and immediately following hurricanes, and then grow rapidly due to the environmental conditions present, as was seen approximately two weeks after Hurricane Maria in Puerto Rico.

Welcome to the tenth edition of the Climate and Health Outlook from the Department of Health and Human Services (HHS) Office of Climate Change and Health Equity (OCCHE).

In areas of the eastern United States where Lyme disease is common, people are most likely to be bitten by blacklegged (deer) ticks during two times of the year: from April through July when nymphs are active, and again from September through November when adults are most active. The Outlook also features information on pediatric heatstroke prevention. Between 1998 and 2022, a total of 937 children died due to heatstroke when left in a vehicle alone, with an average number of 37 deaths each year. Three tips to remember: never leave a child in a car unattended, make it a habit to look in the backseat every time you exit, and always lock the car and put the keys out of reach.
