From The Nurse Re: West Nile Virus and Lyme Disease

Newton residents were diagnosed with both Lyme Disease and West Nile Virus last year. Take steps to avoid getting sick! Mosquito repellant not only works for mosquitoes, but helps repel ticks as well. Use a repellant with DEET, and follow label instructions for concentrations appropriate for children. Avoid being outdoors during peak mosquito hours, particularly once West Nile Virus has been detected in the mosquito population. Remove containers around your home (tires, kid pools, pots, tarps) that could allow mosquitoes to breed. Check your body for ticks after being outdoors and remove them immediately to avoid disease transmission.
