A crash course in changing the world.
Chake is and expression in Paraguay it mean "be warning of..". People of the Ministry of Public Health give me a bunch of this sticker to distribute in the community. There is a National Plan to Prevention of the Dengue Virus implemented for the Ministry of Public Health. You can get more information in the next link: http://www.mspbs.gov.py/dengue/
The distribution on my neighborhood was great, the people are very aware about the subject and almost every body know and care about the situation and what they have to do to collaborate with it.
