    World TB Day: Tuberculosis remains a deadly disease worldwide

The theme of World TB Day 2021 is "The Clock is Ticking" because the world is running out of time to act on global commitments to end Tuberculosis (TB), according to the World Health Organization (WHO).

Tuberculosis is one of the world's deadly diseases. Each day, nearly 4,000 people lose their lives to TB and close to 28,000 people fall ill with this preventable and curable disease. But during the COVID-19 pandemic, global attention to TB has waned.

"The COVID-19 pandemic and the collective responses to it has caused a disruption of TB prevention and treatment services globally, threatening to derail the progress that has been made to date," says Dr. Zelalem Temesgen, medical director of the Mayo Clinic Center for Tuberculosis.

"COVID-19 has rightly been in the spotlight over the last year as a catastrophic infectious disease, but that doesn't mean we can take our focus off of other infectious diseases like tuberculosis," adds Dr. Temesgen. "Alternatively, it also has highlighted, perhaps as has never been done before, the importance of public health."

Dr. Stacey Rizza, a Mayo Clinic infectious diseases expert and executive medical director for Mayo Clinic International, says TB is a deadly public health crisis that knows no borders. She says there are still too many people affected by this disease. "It's estimated that 25 percent of the world's population is infected with TB," says Dr. Rizza.
