Yolanda Foster continues to struggle with Lyme disease, but instead of sitting back and allowing her illness to get the best of her, the reality star has been highly active in raising awareness for the disease.

Yolanda Foster Encourages Fans To Participate In Lyme Disease Challenge

On Instagram, Foster has chronicled her journey since her diagnosis, and in her latest series of posts, she has encouraged fans to participate in the Lyme Disease Challenge, but what exactly is it?

According to the cause's official website, the Lyme Disease Challenge began in March, and is ongoing. The challenge is meant to generate donations and awareness for the disease, which will hopefully lead to the finding of a cure.

Below are the instructions for participating in the challenge, via LymeDiseaseChallenge.org:

1. TAKE A BITE: Bite a lime and TAKE A PHOTO OR A SHORT VIDEO of the act – the more sourpuss your face, the better (and funnier!).

2. SHARE A FACT: State ONE BRIEF FACT ABOUT LYME DISEASE, such as the facts provided below. You can say them in your video, write them on your photo, or include them in your post. Help us spread the true facts about Lyme Disease!

3. PASS IT ON: Keep the campaign going — CHALLENGE THREE OTHER PEOPLE – your friends, family, whomever! – to take a bite! Mention them in your video or if you do a photo tag them in your post.
