People tend to think of malaria as a tropical disease, says Christopher Vitek, a medical entomologist at the University of Texas Rio Grande Valley in Edinburg. “But the fact of the matter is, historically we’ve had a fair amount of malaria transmission here in the U.S.” And the risk of transmission now is not zero.… Continue reading Malaria is not new to the United States
New malaria cases transmitted within the United States have raised alarm bells among health officials. In 2021, there were around 247 million cases of malaria worldwide, and an estimated 619,000 people died from the disease, according to the World Health Organization (WHO). Around 95 percent of cases occur in Africa, and more than half of malaria deaths… Continue reading Malaria surfaces in the US after two decades
Autoridades sanitarias de los condados de Sarasota y Manatee, en la costa oeste de Florida, emitieron una alerta sanitaria tras confirmarse dos casos locales de malaria, una enfermedad común en África y en la India, pero no en Estados Unidos. Detalles en: https://www.elnuevodia.com/noticias/estados-unidos/notas/condados-en-florida-emiten-alerta-de-salud-tras-confirmarse-dos-casos-de-malaria/
Les émergences récentes de maladies à transmission vectorielle ont marqué un tournant en matière de santé publique, ces maladies affectant des territoires de plus en plus éloignés des zones endémiques. Cette situation tire son origine des changements environnementaux et de l’intensification des échanges commerciaux ou de voyageurs entre les continents. Le virus du chikungunya a été signalé… Continue reading LE MOUSTIQUE TIGRE CAPABLE DE TRANSMETTRE LE VIRUS DU CHIKUNGUNYA À DES TEMPÉRATURES TEMPÉRÉES
According to official reports, the death toll from the outbreak has risen to 248 as of June 16, while reported cases have surpassed 146,000. The situation caused the minister of health to step down. It is unfortunate that Dengue has returned to a region that had it under control for years. The full report is… Continue reading Dengue Outbreak in Peru
Although about 2,000 people infected with malaria turn up in the US health care system every year, those cases are all linked to travel outside the US. Neither those involved in the Florida cases nor the Texas case had traveled. That means in both states, the infection was acquired within US borders. There is no reason to… Continue reading Three new malaria cases in the US. The first in two decades.

Studying what mosquitoes are attracted to “gives us some really good clues about what mosquitoes are using to hunt us, and understanding what that is, is essential for us to come up with the next steps.” Details in the link below. https://edition.cnn.com/2023/05/19/world/mosquito-human-body-odor-malaria-scn/index.html
Malaria vectors have spread southward expansion by 4.7 kilometers (nearly 3 miles) every year, and risen 6.5 meters (21.3 feet) in elevation each year. That’s further and faster than previous estimates which reported that across the board, terrestrial species were moving poleward by 1.7 kilometers (1.05 miles) a year and upslope by 1.1 meters (3.6 feet)… Continue reading Malaria vectors are moving
Global malaria prevention and control programs depend almost exclusively on the use of long-lasting insecticidal nets (LLINs), manufactured with materials into which insecticide is incorporated or bound in some fashion to the fibers. They are meant to provide personal protection against malaria by serving as a physical barrier between human and vector and by repelling… Continue reading Durability of long-lasting insecticidal nets (LLINs) in Ethiopia
