Oakland County Keeps an Eye on Mosquito Population

In Oakland County, mosquitoes aren’t just pesky critters — they are under strict watch. The reason? In some rare cases, these tiny creatures can transmit diseases to humans. The county health division is vigilant, however, and tries to keep residents both informed and protected.

Mosquitoes are collected and tested at various spots throughout the county for potential diseases, with the costs largely covered by state grants. Until now, 2024 has been a low-risk year according to officials. However, since mosquito-borne diseases could peak between late July and September, monitoring remains a critical task.

The wet spring may cause a growth spurt in the mosquito population, but it doesn’t necessarily mean an increase in mosquito-borne diseases. Though last year, Oakland County recorded six mosquito pools that were disease-positive and one human case each of West Nile virus and the Jamestown Canyon virus.

Both of these viruses cause no or mild symptoms for most individuals but can result in severe complications like encephalitis, meningitis or paralysis in rare instances. Another disease mosquito can transmit is Eastern Equine Encephalitis (EEE), which can be seriously life-threatening.

During the 2019-2020 EEE outbreak, the virus infected 14 people across the state, claiming eight lives. The vast majority of affected humans were in mid-Michigan and southwest Michigan. Furthermore, EEE can also be harmful to horses. Currently, vaccines are available for EEE in horses, but not for humans.

In terms of prevention, there are no specific treatments for these three viruses apart from rest, fluids, and pain relief. During severe outbreaks, hospitalization might be required. Back in 2019-20, measures like spraying were initiated to control the mosquito population in various counties.

The state hasn’t recorded any human cases of mosquito-borne viruses this year so far. However, five birds from different counties have tested positive for West Nile virus, indicating that mosquitoes can contract these viruses by feasting on infected hosts, such as birds.

To protect against these blood-sucking creatures, public health officials advise the use of insect repellents, which can also be effective against ticks. Additionally, wearing light-colored, long-sleeved clothing and maintaining window and door screens can all help in preventing mosquito bites. It’s also recommended to regularly empty outdoor water bodies like buckets or birdbaths, where mosquitoes typically breed.

So, while the risk may be low this year, being forewarned is being forearmed. This summer, whilst enjoying those warm evenings outdoors, remember to keep both the mosquitoes and precautions in mind.
