Because of Guerrero's disease, she was sent to Tala
Leprosarium in
Novaliches. The institution was filthy, and there was no running water or electricity. It was crowded, and only four nurses looked after 650 patients. Necessities such as food, clothing and bedding were insufficient. Guerrero devoted her time cleaning around the facility. She also helped build coffins for those who died. She wrote a letter to a friend's connection in the US about conditions at the leprosarium. Her letter was forwarded to
chaplains at the
Carville National Leprosarium in
Louisiana, where it was circulated and reached a local publication,
Manila Times. The newspaper's front page published an exposé by
Arsenio Lacson about the institution. Several other mass media sources then reported the story, prompting the local government to investigate. The leprosarium was subsequently renovated. The facilities were cleaned up and improved—new beds were provided, food rations increased, telephones installed, and more medical personnel were added. After hearing from chaplains at the Carville National Leprosarium and learning about the medical breakthroughs concerning leprosy treatment in the United States, Guerrero felt hopeful again. She persisted and became the first foreign national with leprosy to obtain an American visa. In 1948, she became the first foreigner admitted to the Carville National Leprosarium. Within the same year, Guerrero's wartime feats and struggles with leprosy were featured in
Time magazine, and she was awarded the
Medal of Freedom with a Silver Palm. Guerrero was diagnosed with an advanced case of leprosy, which required nine years of treatment at Carville National Leprosarium. She was discharged in 1957. Guerrero became an activist for destigmatizing leprosy. Upon her recovery, Guerrero sought employment, but potential employers would shun her once they discovered her history with the disease. Guerrero was also subjected to deportation back to the Philippines. Her supporters, consisting of military members, the press and lawyers, campaigned for her permanent residency in the US. She was granted citizenship in 1967. Guerrero eventually left the public eye and lived a life of obscurity, maintaining privacy about her former life. She met her adult daughter only once when she visited her in the US. She remarried and never returned to the Philippines. ==Death==
