An Unexpected Pandemic Side Effect In Peru: A Comeback For TB

In late February 2020, Martin Valencia Garcia was working as a community agent in Independencia, one of the denser districts of Lima, Peru. His job was to help people access tuberculosis diagnosis and treatment with the TB Móvil program, part of a larger effort led by the nonprofit health care organization Partners in Health to drastically reduce TB rates in Lima's at-risk communities. TB, which most commonly affects the lungs, is one of the deadliest infectious diseases in the world, and Peru, according to data from 2017, has the highest rate of drug-resistant TB in the Americas.

While working, Valencia Garcia met a 52-year-old man with a cough and invited him to get a scan at the TB Móvil van visiting his neighborhood, one of two in the city with an X-ray machine and artificial intelligence technology. The man's results indicated he needed further tests and treatment, but not long after, the whole country was on lockdown due to COVID-19. Tuberculosis services were limited, and Valencia Garcia suspects the man got tired of waiting. "He could not do the exams, and since he couldn't do the exams, he couldn't be diagnosed and he couldn't receive treatment," says Valencia Garcia. Many people have experienced the same, he adds. Though he was in charge of the man's case, Valencia Garcia says he lost contact with him in late April. As far as he knows, the man was never diagnosed or treated.
