  • Infections will often clear on their own, but antibiotics and cough suppressants can help with treatment.​

Rabies

  • Zoonotic disease that spreads via the nervous system and can be deadly;

  • Transmission: Saliva of infected mammals between species;

  • Symptoms: Fever, decreased appetite, weakness, paralysis, seizures, drooling, and abnormal behavior;

  • Exposure to rabid dogs is the cause of 99% of human rabies deaths world-wide. Rare deaths occur in the U.S.

  • Vaccination is required by law.

Hepatitis
