PHS - Communicable Diseases

This is a broad topic that covers all the programs that address communicable diseases.  There are four main programs: STDs/HIV, Tuberculosis Management, Reportable Diseases and Non-Reportable Diseases.  These programs address the diagnosis and treatment of the disease and includes consultation, health education and follow-up to reportable diseases.

Flu season ahead



Flu Shots are now available at the Siskiyou County Public Health Department

Call and schedule your appointment.

(530) 841-2134. 


Number 1



Take time to get a flu vaccine

  • While there are many different flu viruses, a flu vaccine protects against the viruses that research suggests will be most  common for that season.
  • Flu vaccination can reduce flu illnesses, doctors’ visits, and missed work and school due to flu, as well as prevent flu-related hospitalizations.
  • Everyone 6 months of age and older should get a flu vaccine by the end of October, if possible.


        Number 2


Take everyday preventative actions to stop the spread of germs.

  • Try to avoid close contact with sick people.
  • While sick, limit contact with others as much as possible to keep from infecting them.
  • If you are sick with flu symptoms, CDC recommends that you stay home for at least 24 hours after your fever is gone except to get medical care or for other necessities. (Your fever should be gone for 24 hours without the use of a fever-reducing medicine.)
  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  • Wash your hands often with soap and water. If soap and water are not available, use an alcohol-based hand rub (sanitizers).

  • Avoid touching your eyes, nose and mouth. Germs spread this way.
  • Clean and disinfect surfaces and objects that may be contaminated with germs like the flu.


Number 3



Take flu antiviral drugs if your doctor prescribes them

  • If you get the flu, antiviral drugs can be used to treat your illness.
  • Antiviral drugs are different from antibiotics. They are prescription medicines (pills, liquid or an inhaled powder) and are not available over-the-counter.
  • Antiviral drugs can make illness milder and shorten the time you are sick. They may also prevent serious flu complications. For people with high risk factors, Treatment with an antiviral drugs can mean the difference between having a milder illness versus a very serious illness that could result in a hospital stay. Studies show that flu antiviral drugs work best for treatment when they are started within 2 days of getting sick, but starting them later can still be helpful, especially if the sick person has a high risk factor, or is very sick from the flu. Follow your doctor’s instructions for taking this drug.
  • Flu symptoms include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people also may have vomiting and diarrhea. People may be infected with the flu, and have respiratory symptoms without a fever.
Communicable Diseases - Non-Reportable Diseases

Many diseases can impact our communities without being contagious or easily spread from person to person.   Public Health Services is tasked with protecting the health of our residents by education and assistance in the prevention of these diseases.   Call 841-2134 and ask for the Nurse-of-the-Day for any questions.  

Information about some of these diseases will be included here.

Communicable Diseases - Reportable Diseases

Under California Code of Regulations, Title 17 (Sec 2500), any healthcare provider is required to report known or suspected cases of any Title 17 disease or condition to the local Health Officer. The communicable Disease Team will investigate all disease reports, provide guidance for treatment, prophylaxis and infection control. Reporting of certain diseases may activate state and federal emergency response systems.
