Chief Public Health Officer and Director of the Cambridge Public Health Department Claude Jacob said in a statement, “We urge residents to take precautions against mosquito bites, especially after dusk…You can protect yourself by using repellents, wearing long-sleeved shirts and long pants in the evening hours, and moving indoors if mosquitoes are biting you.”

Symptoms include fever, flu-like illness, and headaches. Anyone who thinks they might have the disease should contact their doctor.

In most West Nile cases, the infection is mild and there are no symptoms but for a small number of people, West Nile can become severe and cause encephalitis or meningitis.
