Katherine Commale has long known what it is like to greet admiring crowds of kids，to have strangers beg for her signature，and to be featured in books and on TV shows.And yet most of her fellow Americans have never heard of the girl，who has helped to save millions of lives in African villages from malaria.The story began when she was only five.
    On a spring night in 2006，Katherine's mother，Lynda，watched Malaria：Fever Wars.The documentary showed the mosquito-borne disease caused millions of deaths in Africa.The next morning，she told her daughter about the program over breakfast.The little girl was particularly troubled to hear that and Lynda switched the topic to things her little girl could do to help，like donating mosquito nets.
    Initially，Katherine tried raising money by selling some old items，but failed.Soon，she and her younger brother Joseph decided to use small dolls to represent African families with Joseph dressed as a large mosquito，to explain to other children how a simple and cheap mosquito net could protect a sleeping child.Then they went to Katherine's Sunday school and other schools.The idea took off.When that first effort ended，Katherine and her family donated ﹩ 1，500 to the United Nations Foundation to purchase mosquito nets.
    Katherine's efforts caught the attention of many international celebrities，such as David Beckham and Bill Gates.When she was six，she attended the first Malaria Awareness Dayobservance （紀(jì)念儀式） at the White House，and later a Clinton Global Initiative event where she met former U.S.President Bill Clinton.Although Katherine's pace slowed down as she entered middle school，her fame was rising around the world.She has even been featured in a board game beside the youngest Nobel Peace Prize winner Malala Yousafzai. "I'm not Malala whatsoever，" she said. "It's just an act of kindness."
