Dengue is primarily carried and transmitted by infected Aedes aegypti, a species of mosquito common to the Riverside County area. While seven human cases of the disease have been reported by Los Angeles and San Diego counties this year, none have been reported in Riverside County.

In addition, it is likely that the seven cases involved people who were traveling elsewhere, according to the statement from the Northwest Mosquito and Vector Control District.

“With fall temperatures, we often spend more time outdoors,” said Jeremy Wittie, general manager for the Coachella Valley Mosquito and Vector Control District. He noted that mosquitoes are more active in the fall and emphasized that wearing repellent is essential to staying healthy.

The district urged residents to take a handful of steps to help control the spread of Aedes aegypti, including eliminating standing water sources where mosquitoes lay eggs. For those planning on traveling to active transmission areas, officials recommended applying repellents with EPA- registered ingredients and wearing long-sleeve shirts, long pants, socks and shoes.

Reported symptoms of dengue include aches and pains (such as eye pain, typically behind the eyes, muscle, joint, or bone pain), nausea, vomiting, and rash, the statement said.

The district urged anyone with these symptoms to avoid mosquito bites and contact a medical provider.

NEW YORK (AP) — The latest versions of COVID-19 vaccines were 54% effective at preventing symptomatic infection in adults, according to the first U.S. study to assess how well the shots work.

The shots became available last year and were designed to better protect against more recent coronavirus variants.

In Thursday’s study, the Centers for Disease Control and Prevention looked at 9,000 people who got tested for COVID-19 at CVS and Walgreens pharmacies, checking who tested positive and whether they had gotten a new shot or not.

The 54% finding is similar to what’s been reported in other countries, and it’s also about what was reported for an earlier vaccine version, said the Ruth Link-Gelles of the CDC, the study’s lead author.

Studies coming out later this year will assess how effective the shot was at preventing symptoms severe enough to send patients to a doctor’s office or hospital, she said.

The CDC recommends the new shots for everyone 6 months and older, but most Americans haven’t gotten them. The latest CDC data suggests only about 22% of U.S. adults have gotten the shots, and only 11% of children. The slow uptake meant that it took longer for researchers to gather enough data to assess how well the shots work, Link-Gelles said.
