  • About New World Screwworm

    What is the New World Screwworm (NWS)?

    NWS is a parasitic fly species (Cochliomyia hominivorax) whose larvae cause a severe condition called obligate myiasis by feeding on the living flesh of warm-blooded animals, including livestock, wildlife, pets, and sometimes humans. Infestations can cause painful, foul-smelling wounds and may be fatal if they are left untreated. 


    How does Screwworm spread?

    Adult female screwworm flies are attracted to open wounds or body openings (including minor injuries, navels, ears, nose, genitals, etc.) and lay 200 to 300 eggs at a time. These eggs hatch into larvae that burrow into living tissue over about 7 days, then drop to the ground to pupate, emerging as adult flies 7 to 54 days later. Each female only mates once, which is why the sterile male eradication technique is effective.


    How to Protect Yourself and Pets/Livestock Against Screwworm

    General Protection for People

    • Keep any open wounds clean, covered, and monitored.
    • Wear long-sleeved clothing, hats, and socks outdoors, especially in areas of known activity. There is currently no known activity in Hays County.
    • Use EPA‑registered insect repellent and treat clothing and gear with 0.5% permethrin.
    • Sleep indoors or use secure screening; if outside, opt for bed nets or screened tents. 

    For Pets and Livestock

    • Inspect animals regularly, checking wounds or body openings, including navels in newborns.
    • Clean wounds as soon as possible, maintain hygiene in animal living areas, and make sure animals receive routine veterinary care.
    • Report any signs of maggots, foul odors, worsening wounds, or unexplained bleeding immediately.

  • About Rabies

    What is rabies?

    Rabies is a disease caused by a virus that attacks the brain and nervous system.


    How does rabies spread?

    Rabies can be spread by the bite of an animal sick with rabies (also known as rabid) or through the saliva of a rabid animal entering a fresh scratch or similar skin injury. In Texas, rabies is most commonly found in skunks, bats, coyotes, raccoons, and foxes.


    How do I protect myself and pets/livestock against rabies?


    Avoid contact: Do not approach, play with, or feed wildlife.


    Rabies vaccination: The best way to protect your pet is to make sure their rabies shots are up to date. Texas law requires all dogs and cats to be vaccinated, and in Hays County, they must get their first shot by 4 months old. Rabies vaccines expire, so your pet will need regular boosters. Your vet will recommend a 1-year or 3-year schedule.

     

    Secure your pet: Prevent your pet’s contact with wildlife such as skunks, foxes, bats, coyotes, and raccoons. When going on walks in unsecured areas, make sure your pet is on a leash.


    Spay or neuter your pets to protect them from rabies: This procedure makes pets less likely to wander or look for mates, which lowers their chances of meeting wild animals that could have rabies.


    Act quickly if an exposure occurs: If a human or pet is bitten or scratched, wash the wound with soap and water immediately and see a doctor or veterinarian.

  • What happens if I am exposed to rabies?

    If you have been bitten, scratched, or exposed to an animal suspected of having rabies, you should seek medical care immediately.


    Hays County residents should go to an emergency room for wound care and rabies post-exposure prophylaxis (PEP). Rabies PEP is a series of treatments that helps prevent rabies after a possible exposure.


    Ascension Seton Hays ER, Baylor Scott & White Medical Center – Buda, and CHRISTUS Santa Rosa San Marcos ER currently have rabies PEP available. If you are unable to visit either location, please call your nearest emergency department to confirm availability.

  • Health information for the Public

    To protect yourself and your pets/livestock: 

    • Keep dogs, cats and livestock currently vaccinated against rabies (following state and local rules).
    • Keep pets indoors at night (if possible) and supervise them when they do go outside.
    • Seek immediate veterinary care for a pet if it comes into contact with a raccoon, skunk, fox, bat, coyote, or other animal behaving in a way indicative of rabies.
    • Avoid contact with and feeding of wildlife.
    • If you have been exposed to rabies, seek medical care immediately including post-exposure prophylaxis, which is a series of shots that can protect you from rabies.
    • Symptoms of rabies in humans include fever, headache, nausea, vomiting, agitation, anxiety, confusion, and difficulty swallowing. Seek care immediately if you are displaying symptoms.
  • Health information for Medical Providers

    Please visit this link to the Centers for Disease Control and Prevention webpage for information about patient care for preventing rabies.

  • Health information for Veterinary Clinics

    Currently vaccinated pets should be revaccinated immediately and restrained (confinement and leashing) for 45 days.


    Unvaccinated pets should be vaccinated and placed in a strict isolation for 90 days and given booster vaccinations during the 3rd and 8th weeks of isolation. If that is not possible, unvaccinated pets bitten by a known rabid animal should be humanely euthanized under public health regulations. 


    Vaccination is the best way to prevent this tragic outcome.
