New Mexico health officials warn of possible long ‘mosquito season,’ West Nile virus risk

New Mexico Department of Health officials on Thursday said residents should prepare for a possible extended mosquito season, and people with weakened immune systems should be particularly cautious about avoiding bites.

Mosquitos transmit West Nile virus, with cases normally arising in late summer. However, officials said fall forecasts of heavier rain and higher temperatures could extend the risk of mosquitos-born illnesses well into fall.

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

A state health news release cited new studies showing people taking medications that affect the immune systems known as B cell-depleting or B cell-modulating medications face higher risks for severe disease from viruses such as West Nile, and recommended residents on such medications discuss those impacts with their doctors.

Officials also urged residents to take precautions against mosquito bites by using repellants approved by the Environmental Protection Agency; wearing long sleeves and pants at dusk and dawn; removing any water-holding items from the home or yard; and ensuring doors and windows have secure screens to keep mosquitos out.
