This alert has been closed and is no longer available.

You can participate if you are:

  • 18 years or older
  • Farmworker, farmer, or veterinarian
  • Work in agriculture, or in close contact with livestock

 What happens if I say yes, I want to be  in this study?

We  will  ask  you  to  answer  some  questions  about  your  occupation and work history and provide a blood sample.  The blood will be sampled by placing a needle in the vein  of the arm. A small tube of blood will be taken. All this will  take about 30 minutes.

After you have responded the questions and a professional  has  taken your blood  sample in a health  facility, you will  receive $60  in  compensation.  The  survey  and  the  blood  collection  are  completely  anonymous;  we  will  not  ask you to identify yourself.

Help us to control Leptospirosis

Leptospirosis is a disease caused by the bacteria Leptospira that affects people and animals. Agricultural workers, farmers and veterinarians can be easily infected. People who have direct contact with dirty water and animals are at the greatest risk.

What are the symptoms of leptospirosis? 

Most people have no symptoms or have very mild symptoms consisting of fever, headache, chills, red eyes and muscle pain for a few days. These symptoms are easily confused with a simple cold. Unfortunately, in some people, leptospirosis persists and affects the kidneys, liver, lungs, eyes, heart and brain.
