(Portland, OR) -- With the arrival of summer last Friday, the Oregon Health Authority has tips to keep you safe. Don't swim alone or swim in bad weather and supervise children in or near water. During extreme heat, stay in air-conditioned places and limit exposure to the sun, especially between 10 a.m. and 4 p.m. Eliminate standing water around your home to reduce mosquitoes. Wear long sleeved shirts and pants along with repellent to avoid being bitten by mosquitoes that can carry diseases like West Nile virus.
