​​Rabies Information

Rabies is a preventable viral disease that mainly occurs in mammals. Humans can contract the rabies virus if bitten by an animal infected with rabies. In the U.S, rabies infection has been mostly present in wild animals such as raccoons, skunks, and bats. Domestic animals such as dogs and cats account for less than 10% of the reported rabies cases. For more information concerning rabies, visit the Center for Disease Control and Prevention Rabies Information.

You can find the Texas Department of State Health Services' (DSHS) guide to Rabies prevention and treatment by clicking here.

Patients - How to Obtain Rabies Biologicals for Bite Victims

CCHCS does not provide pre-exposure rabies vaccinations to the public for travel purposes or for veterinary students/professionals.

If you are scratched, bitten, or have some other type of exposure to an animal you feel may have rabies, go to your nearest hospital emergency room immediately. Additionally, you will need to notify your primary care physician since a medical evaluation is required to determine whether post exposure prophylaxis (PEP) is appropriate in your situation.

If the injury was caused by an animal that can be located (dog or cat living in a neighborhood) it must be reported to the Local Rabies Control Authority (LRCA) and they will determine if and how the animal is quarantined (see Reporting Animal Bites and/or Exposure to Rabies below).

Please see the following for detailed instructions on obtaining rabies biologicals.

Health Care Providers - Obtaining Rabies Biologicals for Post exposure Prophylaxis

Health care providers are required to report animal bites and/or possible rabies exposure to the Local Rabies Control Authority (LRCA). See the links under Reporting Animal Bites/Exposure to Rabies below.

If you are a health care provider needing to obtain rabies biologicals (PEP) for your patient, please contact our office at (972) 548-4707 during normal business hours. If it is after hours, please call (972) 547-5350. For after-hours calls, you will reach the Sheriff's dispatch office. Let them know you need to speak to the Epidemiology department about rabies. An on-call Epidemiology team member will be contacted.

Mo​squito-Borne Diseases

Collin County collaborates with local cities to conduct surveillance activities for West Nile Virus and other mosquito-borne diseases such as Chikungunya, Zika and Dengue. Currently there are no locally acquired cases of Chikungunya, Zika or Dengue in Collin County. Mosquito bite prevention is the best way to prevent the spread of mosquito-borne diseases.

Please visit Zika in Texas to obtain additional information for the State of Texas. Zika is a virus that is primarily spread through mosquito bites. Transmission may also be spread from mother to child during pregnancy. The spread of the virus through blood transfusion and sexual contact have also been reported.

Most people infected with the virus generally display mild or no symptoms. Those that develop symptoms may display mild illness that can last several days or up to several weeks. The most common symptoms of the Zika virus are fever, rash, joint pain, and conjunctivitis (red eyes).

Pregnant woman or woman that may become pregnant should be cautious in active Zika areas. The virus has been linked to the birth defect microcephaly, a condition where a baby's head is much smaller than expected and may cause developmental delays.

Most Zika cases in Texas are related to people infected through mosquito bites while traveling to areas where Zika is spreading. Travel guidance is available through the Center for Disease Control (CDC) website.

Questions about testing for the Zika virus? Additional information is available on the CDC's Testing for the Zika Virus site and/or please visit: Zika in Texas for the most current information available on Zika testing procedures.

Please visit our West Nile Partners page to find more information about the activities of area cities and municipalities.
