Current Community Outbreaks

Syphilis Outbreak

What you should know!

Southwest Idaho is currently experiencing an outbreak of syphilis. Syphilis is a sexually transmitted bacterial infection that has been affecting our community dramatically since Fall of 2020. Syphilis is spread through oral, genital, or anal sex with an infected person and can increase your risk of contracting or spreading HIV. If left untreated, syphilis can cause serious health problems such as blindness, neurological damage, organ damage and can be fatal.

Luckily, syphilis can easily be cured with antibiotics and if it is treated early, it can prevent long-standing health complications that can occur when it goes untreated. Since the fall of 2020, we have seen two congenital syphilis cases: when a mother passes the syphilis infection on to her baby during pregnancy. This can be very serious as it may lead to very serious health issues including stillbirth, neonatal death, or severe chronic health conditions. If you are pregnant, you should be tested at least once during pregnancy

Everyone should be tested at least once in their life! Those that should be tested every 6 months are those who:

  • Have anonymous sex partners
  • Have multiple sex partners
  • Have had sex with someone known to have tested positive for syphilis
  • Have had a past STI and are sexually active
  • Have sex while intoxicated or high
  • Are a man who has sex with men
  • Are living with HIV and are sexually active
  • Are taking PREP for HIV prevention

To prevent infection, wear a condom or get tested frequently to stay on top of your health!

Hot topics in SW Idaho

Summer season brings an increase in mosquito and tick activity in Idaho. This increase in activity also brings an increase in vector-borne disease transmission. Common symptoms of arboviral diseases include fever, headache, body aches, joint pain, vomiting, diarrhea, rash, and lethargy. In cases of severe arboviral infections, neurological symptoms of encephalitis, seizures, coma and paralysis can occur.

If you are experiencing any of the above mentioned symptoms talk with your doctor about testing.

To help prevent exposures to arboviral diseases from mosquito and tick bites, use insect repellents with DEET, Picaridin, IR3535, Oil of lemon eucalyptus (OLE), Para-menthane-diol (PMD) or 2-undecanone. For more information about which insect repellent may be right for you, check out the United States Environmental Protection Agency’s (EPA) site on repellents: https://www.epa.gov/insect-repellents

Other prevention methods include wearing long pants and shirts that are pre-treated with permethrin. Do not use permethrin products directly on your skin.

Always check yourself and pets for ticks after being outdoors, especially under arms, in and around ears, inside belly button, back of the knees, in and around the hair, between legs and around the waist. Showering within two hour of being outside also helps wash off unattached ticks. See more information on tick bites at https://www.cdc.gov/ticks/avoid/on_people.html.

Lastly, take steps at home by using screens on doors and windows, repairing any holes, and turning over any items that may have standing water (i.e. tires, buckets, planters, toys, pools, birdbaths, flowerpots or trash containers). Check these weekly!

What We Do

There are over 70 reportable diseases and conditions in Idaho. When one of these conditions is reported, Southwest District Health (SWDH) Epidemiologists (Epis) will investigate the illness and work to establish the source of the infection, determine whether others have been exposed, and if an outbreak has occurred. Epis may make recommendations to restrict people from daycare, school, or work while they are infectious to prevent further spread. Epis sometimes make recommendations for those who have been exposed to an infectious disease to receive an immunization, test, or treatment to prevent them from becoming ill. SWDH Epis also offer case management for active tuberculosis (TB) which includes a way to help clients to take their TB medications called Directly Observed Therapy or DOT.

If you need to get in touch with an Epi, please call 208-455-5442.
