Bugs We Hate Part 2 - Mosquitoes

What are “vector-borne diseases”?

Ticks and mosquitoes are not only pesky and annoying, but they can carry some nasty diseases. Diseases transmitted from their bites are called “vector-borne diseases.” There are long lists of vector-borne diseases, but we will focus on just a few here.

Mosquitoes

Mosquitoes can transmit a variety of illnesses, and like ticks, the initial symptoms may be similar and vague:

  • Zika virus symptoms (Puerto Rico, Mexico): fever, rash, headache, joint pain, conjunctivitis (red eyes), muscle pain
  • West Nile virus symptoms (USA): fever, headache, body and joint pain, weakness, vomiting, diarrhea, rash
  • Dengue virus symptoms (Puerto Rico, USA in rare cases): aches and pains (eye pain typically behind the eyes, muscle, bone, joint pain), nausea/vomiting, rash
  • Malaria parasitic disease symptoms (USA in rare cases): flu-like illness (fever, chills, headache, body ache, tiredness, nausea/vomiting, diarrhea) and sometimes yellow skin or eyes (Jaundice).

Infections of the brain (encephalitis) are possible with many of these mosquito vector-borne diseases. If you or a colleague become ill and have had recent mosquito bites, please seek medical attention. Many of these potential illnesses require very specific tests and a high index of suspicion based on the healthcare provider knowing you have been bitten.

These bites can also become infected through scratching and the dirty environment we work in. Watch for unusual spread of redness, warmth, streaks, or other signs of skin infection.

The Best Medicine is Prevention!

  • Spray your outdoor clothing, shoes, tent, and other gear with a repellent that is 0.5% permethrin.
  • Use a repellent with DEET – 20% is recommended.

Bite Care

  • Apply a mixture of baking soda and water, which can help reduce the itch response.
    • Mix 1 tablespoon baking soda with just enough water to create a paste.
    • Apply the paste to the mosquito bite.
    • Wait 10 minutes.
    • Wash off the paste.
  • Use an over-the-counter anti-itch, hydrocortisone, or antihistamine cream to help relieve itching. Follow the product label directions.
