Health officials say above-average rain and heat may keep West Nile virus risk elevated until the first hard freeze

Organ Mountain News report

SANTA FE - New Mexico health officials are warning that mosquito season could last longer than usual this year, potentially extending the risk of West Nile virus well into the fall.

The New Mexico Department of Health said above-average rainfall and heat forecast through October could prolong mosquito activity across the state.

“With above-average rain and heat forecasted for New Mexico through October, mosquito season may last longer than usual,” said Dr. Erin Phipps, state public health veterinarian. “West Nile virus is expected to persist until the first local hard freeze.”

West Nile virus is the most common mosquito-borne disease in New Mexico, with most cases typically occurring in late summer.

Health officials said people with weakened immune systems should take particular precautions. Recent studies have found that people taking medications that deplete or modify B cells may face a higher risk of severe illness from viruses such as West Nile.

NMDOH recommends that people talk with their doctors about medications or health conditions that may affect their immune systems and their risk from mosquito-borne illness.

Symptoms that should prompt medical attention can include headache, fever, weakness, loss of balance and confusion.

The department recommends using EPA-approved insect repellents containing DEET, picaridin, IR3535 or oil of lemon eucalyptus/para-menthane-diol when going outside.

Residents can also reduce their risk by wearing long sleeves and pants at dawn and dusk, removing standing water from items such as old tires and cans, draining birdbaths and plant saucers weekly, screening rain barrels and making sure window and door screens fit tightly.
