Fight the Bite

West Nile Virus has been detected in mosquitoes in Cook County. Prevent mosquito bites and the diseases they carry – like West Nile Virus. Practice the 3 R’s at dawn and dusk: Remove standing water and trim bushes and grass around your home. Repair torn screens. Repel mosquitoes using insect repellent.

H5N1 Bird Flu Update

The CDC is investigating a multi-state outbreak of highly pathogenic avian influenza (H5N1) among poultry and dairy cows with one recent human transmission detected in a Texas dairy worker. While the current public health risk is considered low for the general public, dairy and cattle workers, hunters and people who work with infected or dead birds or animals are at higher risk for infection, and personal protective equipment (PPE) is recommended.

Avoid Bat Bites

Bats can carry rabies, a potentially deadly disease. If you have had physical contact with a bat, wash the affected area thoroughly with soap and water and contact a healthcare provider immediately to discuss post exposure prophylaxis. If possible, contain or capture the bat safely, so it can be tested for rabies.

Get Naloxone

Opioid-involved overdose deaths are preventable with Naloxone, an easy-to-use medicine. Be prepared.Get Naloxone. Safe a life.
