COVID-19 isn’t the only highly infectious disease on the rise. Tuberculosis (TB) has also seen an increase, with cases going from 263,000 in 2020 to 311,000 in 2021, per the National TB Registry. Globally, the Philippines is the fourth largest contributor to TB cases.
“Before COVID-19, TB was the leading infectious cause of morbidity and mortality in the world,” says Gregorio P. Ocampo, MD, from the Section of Pulmonology of the top hospital in the Philippines, Makati Medical Center (MakatiMed). “Although cases of TB have gradually declined, efforts to curb the spread of COVID-19 have, as the WHO pointed out, reversed years of progress in the fight against TB.”
Like most diseases, early detection and compliance with treatment ensure a complete recovery from TB. The MakatiMed health expert cites five fast facts on the infectious disease that has resulted in the death of millions.
TB is caused by bacteria. “An airborne disease that spreads when an uninfected individual inhales the droplets of an infected person’s cough, sneeze, or saliva, TB is caused by the bacterium mycobacterium tuberculosis,” says Dr. Ocampo.
Often associated with poverty, TB is usually found in highly dense communities of low- and middle-income countries. Persons with compromised immune systems, such as the malnourished and those with HIV/AIDS, are vulnerable to this disease. Smokers are also twice as likely to be infected with TB compared to non-smokers.
TB has similar symptoms to other diseases. “A persistent cough (sometimes with blood in the mucus), fever, chills, weight loss, loss of appetite, and fatigue are classic symptoms of TB,” Dr. Ocampo explains.
But they’re also symptoms of other diseases – COVID-19 and lung cancer, to name two.
Health specialists can begin their diagnosis by listening to you breathe with a stethoscope and checking for swollen lymph nodes. They will likely order a TB skin test or blood test. “These will tell whether you are infected with the TB bacteria,” Dr. Ocampo points out. “Your doctor will also request for a chest x-ray and sputum test to detect the presence of active TB.”
You can have TB and not know it. Latent TB means you don’t feel sick or show any of TB’s symptoms even if your skin or blood test confirms you have the TB bacteria.
TB is curable. “A number of antibiotics are prescribed to a patient to take for an average of six months,” says the MakatiMed doctor. “Take these antibiotics as instructed by your physician and complete the recommended course of treatment. Failure to do so may not completely kill the TB bacteria or make it resistant to drugs.”
TB is preventable. Though there are no vaccines to protect you against TB, simple and mindful health habits can keep you free of this infectious disease. “Cover your mouth with a tissue, handkerchief, or the crook of your elbow when you cough or sneeze. Wash or sanitize your hands after coughing or sneezing. Wear a mask when you’re in crowded places or with someone exhibiting symptoms of TB. Eat a healthy diet. Keep your surroundings well-ventilated. Don’t share glasses or utensils with a person exhibiting TB symptoms. And see a doctor once you start showing symptoms yourself,” says Dr. Ocampo.
