SAUGUS – The Massachusetts Department of Public Health (MDPH) announced Friday that West Nile virus (WNV) has been detected in mosquitoes collected from Saugus.In 2009, health officials tested 3,410 mosquitoes for WNV and 26 of these samples tested positive. Saugus had 1 WNV positive sample from 2009. The number of mosquitoes that tested positive this time around is undisclosed at this point.WNV is most commonly transmitted to humans by the bite from an infected mosquito. While WNV can affect people of all ages, people aged 50 and older are at the highest risk for a severe infection.Although WNV brings cause for concern, small precautions can be taken to better avoid mosquitoes and/or an infectious bite. Being aware of peak mosquito biting hours (from dusk to dawn) is one of these precautions. Consider rescheduling outdoor activities in the early morning and late evening if possible. If not, take extra care to wear protective clothing and insect repellent. Repellents with DEET in them are strong protectors against WNV, however, it’s recommended that DEET products do not get used on children under three years of age.Installing tightly fitting screens is also helpful in keeping the pesky insects out of your home. Unfortunately mosquitoes tend to enjoy entering homes almost as much as they enjoy the outdoors.Finally, mosquitoes lay their eggs in standing water; therefore limiting the number of places around your home with standing water is advised. A few locations that may have accumulated standing water may be wading pools, unused flowerpots, recycle and trash bins, etc. Also be sure to change birdbath water on a regular basis.The Board of Health is continuing to work with the MDPH about the recently positively tested mosquitoes in Saugus. Until MDPH receives more information, take these small steps to protect yourself and your loved ones.
