Swarms Of Mosquitoes Kill Horses And Livestock After Hurricane Laura

The mosquito population in Louisiana exploded after the rains from Hurricane Laura receded. Thousands of the insects attacked horses, cows, deer and other livestock, causing them to pace or run in the heat until they were exhausted.

Some areas of the state faced massive clouds of the bloodsucking insects in the days after Hurricane Laura made landfall as a Category 4 hurricane on Aug. 27, reported a Louisiana State University AgCenter veterinarian. Spraying efforts have since brought the mosquito population under control.

Though residents in the area are used to mosquito population spikes after heavy rains, the amount of mosquitoes seen after Huricane Laura were unprecedented. It is estimated that farmers located near where the hurricane made landfall lost between 300 and 400 head of cattle, said Dr. Craig Fontenot, a vet based in Ville Platte.

Thankfully, the species of mosquito involved in the outbreak doesn't transmit human disease easily, but people are still urged to take precautions. At the height of the outbreak, any exposed skin was immediately covered in insects. Though humans could wear long pants and sleeves, livestock were unable to get away from the insects, many of them pacing or running until they were exhausted, leaving them susceptible to weight loss and disease.

African Horse Sickness Loosens Hold On Thailand

The African Horse Sickness outbreak that affected Thailand has now been resolved in multiple provinces. Efforts to eradicate it elsewhere in the country are ongoing. The provinces Thailand's Department of Livestock Development reported resolved are: Chaiyaphum, Sa Kaeo, Ratchaburi, Chonburi and Prachuap Khiri Khan.

Carried by biting midges, the virus kills nearly 90 percent of the horses it infects; Thailand's first experience with the virus began in February. Efforts to control the spread of infection have included establishing surveillance and containment zones, restricting movement, quarantine and disinfection. Barns housing horses have been wrapped in plastic or fine mesh and regularly fumigated to keep the insects away from horses.

Nearly 6,000 African Horse Sickness vaccines have been administered, some of which have been given to zebras. There is suspicion that the disease was brought to Thailand through zebra importation; the import of zebras was terminated on April 8.

It is reported that between 150 and 500 horses have died.
