(NEW YORK) — A record number of West Nile virus cases have been recorded for this time of year, the Centers for Disease Control and Prevention (CDC) warned on Wednesday ahead of the upcoming holiday weekend.

At least 48 cases of West Nile have been reported so far this year compared to an average of 10 typically by the end of June. This is the highest number of infections reported at this point in year since 2004, according to the federal health agency.

Additionally, at least 23 states are reporting West Nile activity, which is the highest number recorded over the last 10 years, CDC data shows.

The illness is the leading cause of mosquito-borne disease in the contagious U.S., with several thousand cases and over 100 deaths reported on average each year.

With millions gathering outside for Fourth of July, the CDC is urging Americans to take precautions and reduce their risk of mosquito bites.

Since 1999, the disease has killed more than 3,300 Americans. Cases have historically peaked in August and are mostly reported from June through October.

While many people infected do not develop symptoms, about one in five do. Symptoms include fever, headache, body aches, vomiting, diarrhea or rash, according to the CDC.  Most symptoms soon disappear, though weakness and fatigue may last for weeks or months.

Fewer than 1% of people infected develop severe illness that affects the central nervous system, including inflammation of the brain (encephalitis) and the membranes around the brain and spinal cord (meningitis), the CDC says.

Risk of severe disease, hospitalization and death increase with older age; certain medical conditions including cancer, high blood pressure and kidney disease; and a weakened immune system.

There are currently no vaccines for West Nile virus, nor disease-specific treatments. The CDC recommends rest, fluids and over-the-counter medications to treat the infection. Those with severe illness may need to be hospitalized and receive additional support treatments, such as intravenous fluids.

Jobs report shows US unexpectedly lost jobs in July

(Win McNamee/Getty Images)(WASHINGTON) -- The U.S. economy unexpectedly lost jobs in July, demonstrating a wobbly labor market as shoppers continued to withstand a surge of inflation set off by the Iran war.The U.S. lost 23,000 jobs in July, according to the federal government's monthly jobs report, which marked a decline from 57,000 jobs added in June.The unemployment rate fell slightly from 4.2% in June to 4.1% in July, the Bureau of Labor Statistics (BLS) said. Unemployment remains low by historical standards.The lackluster figure recorded in July departs from largely resilient performance for the labor market so far in 2026, despite a historic oil shock that has driven up fuel prices and hiked supply-chain costs for a host of other goods.A government report issued last week showed a steeper slowdown in gross domestic product than expected over three months ending in June, however, suggesting strain in the underlying economy over the early months of the war.The U.S. added an average of 92,000 jobs per month over the first half of 2026, U.S. Bureau of Labor Statistics data showed. That pace marks an improvement from an average of about 7,000 jobs lost per month over the second half of 2025.The Iran war drove up gasoline prices and catapulted inflation to a three-year high in May. A preliminary peace agreement in June offered up some relief, but a burst of on-again, off-again fighting in recent weeks caused crude prices to rise again.The combination of elevated inflation and a resilient labor market has raised the chances of an interest rate hike, futures markets show. Investors peg the odds of a quarter-point rate hike next month at about 56%, according to the CME Group's FedWatch Tool, a measure of market sentiment.The Fed opted to hold interest rates steady at its meeting last week, but central bankers appeared divided over the move. Three of the 12 members on the Fed's policymaking board voted in favor of a rate hike, marking the largest number of dissenters casting ballots in the same direction since 2016.A rate increase, however, could risk a slowdown in hiring and economic growth over the coming months as corporations face the prospect of higher borrowing costs.The benchmark rate stands at a level between 3.5% and 3.75%. That figure marks a significant drop from a recent peak attained in 2023, but borrowing costs remain well above a 0% rate established at the outset of the COVID-19 pandemic.Fed Chair Kevin Warsh, who took the helm of the central bank this summer, has repeatedly vowed to dial back inflation."The committee remains resolute -- you’ve heard this before -- that we will deliver price stability," Warsh told reporters in Washington, D.C., last week.Copyright © 2026, ABC Audio.
