Activism In 2006, Omanyo started a fumigation campaign to get rid of
jigger fleas. The campaign is ongoing and has led to hundreds of homes being treated. In 2017 she had her third attempt to be elected a member of parliament. Only a small number of women are elected despite a law that requires a gender balance better than two-thirds. In 2021 Omanyo's school was chosen as one of the top four choices for giving to improve education in an article in
The New York Times. The author, Peter Coy, recommended the
Wikimedia Foundation, the
Khan Academy,
Children International, and Omanyo and her school. Coy chose Omanyo because he had previously given to the school. In September she announced a Sh 10 million fund that would action a 2017 order by Kenya’s Fourth President
Uhuru Kenyatta. She said that pads and not money would be distributed across the country and funds had been put aside by Cabinet Secretary for Public Service
Aisha Jumwa to pay for them.
Political career In 2022, Omanyo was elected to
National Assembly (Kenya) as
county woman representative for
Busia County. She is one of ODM's Deputy Secretary Generals and was selected as acting Secretary General on 11 February 2026, when
Edwin Sifuna was removed. However, his removal was halted by the Political Parties Disputes Tribunal (PPDT) on 12 February. ==Support==
