A cure for flea and tick bites in pets could prevent the diseases of zika and malaria in humans, according to a study published today. in the Newspaper Researchers at Calibr Institute in the Netherlands discovered that a class of drugs called isoxazolines that is sold in veterinary products to protect animals against fleas and ticks. also kills mosquito species carrying diseases that feed on human blood.
"Our results suggest that isoxazolines could be effective in controlling epidemics of diseases transmitted by mosquitoes and other insects in areas with limited medical infrastructure," said Peter Schultz, executive director of Calibr
Dutch scientists have determined that the administration of drugs with isoxazole has less than a third of the population in areas prone to seasonal outbreaks of diseases transmitted by insects could prevent up to 97% of all cases of infection.

Plasmodium vivax, which causes 16 million cases of malaria a year in the world, s. adapted to local circumstances for thousands of years, an adaptability that makes this parasite a challenge.
In 2016, about 216 million people have contracted malaria worldwide and 445 milmuron because of this disease, according to data from US Centers for Disease Control
Zika, has spread rapidly across the planet in recent years and now found in 90 countries.
When administered orally to animals, flea medications are absorbed into the bloodstream and spread throughout the body, where they remain active for up to three months.
It is well tolerated by dogs and cats, drugs destroy fleas and ticks that feed on the blood of treated animals by damaging the nervous system of insects.
Based on existing data, the researchers estimated that a single human dose of this drug would transmit an insecticidal effect against mosquitoes carrying Zika and malaria for 50 to 90 days.
"Isoxazolines could be administered before the onset of seasonal diseases to transmit protection until the threat decreases at the end of the season." Said Matt Tremblay, a member of the 39, research team
The authors noted that drugs might not work as vaccines because a person treated could still contract a disease following an insect bite.
However , an insect biting a person in this treatment would die before transmitting the disease to other individuals, an effect that, multiplied in a large population, would reduce the total number of infections.
