Takeaways

• 😀 TB is spread through the air when someone with TB disease in their lungs or throat coughs, sneezes, sings, laughs, or speaks.
• 😀 TB germs are invisible and can linger in the air, making it easy to inhale them, especially in close contact situations.
• 😀 TB cannot spread through physical contact like handshakes, sharing utensils, or kissing.
• 😀 People who spend a lot of time with someone infected with TB, such as family members or coworkers, are at higher risk of getting infected.
• 😀 A person may develop TB disease shortly after infection or years later, and it often affects the lungs, but it can affect any part of the body.
• 😀 Pulmonary TB (lung TB) is the most contagious form of TB and is more likely to spread to others.
• 😀 TB can be spread even before a person is diagnosed, making early detection and treatment critical to preventing the spread.
• 😀 A contact investigation is essential for identifying people who might have been exposed to TB and ensuring they get tested and treated if necessary.
• 😀 Patients with TB should take actions like isolating themselves, wearing a mask, covering their mouth when coughing or sneezing, and ensuring good ventilation to prevent spreading the disease.
• 😀 TB is treatable and curable with proper medication, but it is important to complete the full course of treatment to avoid relapses and prevent the spread of TB again.
