Very hot weather can make people sick, even healthy adults. Older adults, those who are pregnant, infants and young children, people experiencing homelessness, and people with pre-existing health conditions are at higher risk.
If you see someone on the street who needs help, you can call the Office of Homeless Services outreach hotline at 215-232-1984. If you think someone is having a medical emergency, call 911.
