PAHO Brazil needed to engage people who might be sexually active with effective communications about how to protect themselves from Zika.


PAHO Brazil used posts on its Facebook Page to reach more than half a million people in less than 48 hours with a critical message about preventing the sexual transmission of Zika.

  2. Spending less than $600, PAHO Brazil was able to reach more than half a million people in less than 48 hours. More than 24,000 people engaged with this post, and more than 4,450 people shared it with their own friends, further spreading the message.

Campaign Lessons

“Brazilians are using Facebook to help take care of their friends. We were surprised with how many Brazilians never heard that Zika could be sexually transmitted. Although that information had been circulating in the press and on institutional websites for a while, it was on our Facebook Page that people learned about it. As a result, more than 5,000 people shared this post, reaching more than 600,000 people on Facebook.” – Luís Felipe Sardenberg, Communications Focal Point, PAHO/WHO Brazil
