Aliyah Kateregga, a mother of three, beams as she welcomes Betty, the community health worker (CHW) who has been a lifeline to her family, into her home in Kamugombwa Village, Masaka District, Central Uganda.

Aliyah, a farmer, is known in her community for keeping a clean and orderly home. Her three-year-old son rushes up to Betty, wrapping his arms around her and showing off a small bruise on his hand. With a warm smile, Betty gently examines his hand.
