Mycobacterium tuberculosis, the bacteria that causes tuberculosis (TB), is distinct from most germs in its capacity to silently infect individuals for months and even years before waking up and causing active disease that can lead to severe illness and death.

Apr 23 2024Boston University School of Medicine Mycobacterium tuberculosis, the bacteria that causes tuberculosis , is distinct from most germs in its capacity to silently infect individuals for months and even years before waking up and causing active disease that can lead to severe illness and death. The immune system plays an important role in controlling the germ and keeping it dormant.

In a new study that followed household contacts of persons with TB, researchers have found that undernourished household contacts were three times more likely to progress to TB disease. The study did not find that undernourished contacts were at increased risk of testing positive for TB infection as compared to well-nourished individuals.
