"Invasive Disease-Spreading Mosquitoes Threaten California Communities"

Invasive Aedes aegypti mosquitoes, capable of transmitting diseases like Zika and dengue, have been found in several California counties, including San Diego. The California Department of Health has been monitoring these mosquitoes as part of a statewide surveillance system. Additionally, limited local transmission of dengue virus has been reported in various California counties. Residents are advised to take precautions such as eliminating standing water, using insect repellent, and wearing protective clothing to prevent mosquito bites.

"Dengue Virus Spreads Locally in Southern California, Long Beach Reports First Cases"

Long Beach, California, has reported its first locally acquired case of the dengue virus, following a similar case in Pasadena. Health officials emphasize that the risk of local exposure remains low and urge residents to take preventive measures such as eliminating standing water and wearing insect repellent. Dengue cases in the United States typically occur in people who have traveled to countries where the disease is more common, but neither the Long Beach nor Pasadena patients had any recent travel history. Symptoms of dengue include fever, nausea, vomiting, rash, and body aches, with most patients recovering fully within two weeks.

Unprecedented Dengue Virus Case Detected in California

The first locally acquired case of dengue virus, also known as "break-bone fever," has been reported in Pasadena, California. This is an extremely rare case of local transmission in the continental United States, not associated with travel. Public health officials are conducting surveillance and taking preventive measures to control the spread of the virus, including mosquito population assessment and testing. While most cases of dengue virus are asymptomatic or cause mild symptoms, extreme cases can be fatal. The virus is rare in the U.S., with most cases found in travelers, but about half of the world's population is at risk of dengue, particularly in tropical and subtropical climates.

"Dengue Virus Outbreak Sweeps Through Florida Counties, Alarming Health Officials"

Health officials in Florida have issued a mosquito-borne illness alert for Broward County as cases of dengue virus continue to spread. Two locally-acquired cases were reported in Broward County, joining the majority of cases in Miami-Dade County. So far this year, there have been 10 locally-acquired cases in Florida, with most occurring in July. Additionally, there have been nearly 200 cases reported in individuals with a travel history to dengue-endemic areas. Dengue is transmitted through mosquito bites and is not typically found in Florida, but infected travelers can introduce the virus to local mosquitoes. The Centers for Disease Control and Prevention has reported a total of 225 dengue cases across the United States this year.

Global Dengue Crisis: WHO Warns Half of World Population at Risk

The World Health Organization (WHO) has warned that approximately half of the world's population is at risk of contracting the mosquito-borne dengue virus. Dengue cases have increased eightfold between 2000 and 2022, reaching 4.2 million cases. However, the actual figure may be higher as reporting has become more accurate in recent years. Dengue affects around 129 countries, with an estimated 100 to 400 million cases reported daily. The only available vaccine, produced by Sanofi Pasteur, has an average efficacy of 65% against the four versions of the dengue virus. Dengue deaths range between 40,000 to 70,000 per year, with a case fatality rate of less than 1% in most countries.

Study Reveals Mosquito Saliva's Immune System-Suppressing Properties.

The saliva of a mosquito carrying the dengue virus contains a substance that can suppress the human immune system response and increase the risk of infection, according to new research. Scientists identified a specific type of viral RNA called sfRNA in the infected mosquito saliva, which blocks the defense mechanisms the human body puts up against infection. The sfRNA payload increases virus infection levels, laying the groundwork so that the human body isn't quite so well prepared for attack. The discovery can lead to better preventive measures against the dengue virus right from the moment of infection.
