Tuberculosis (TB) remains a significant global health threat, affecting millions of people annually. While TB primarily impacts the lungs, it can also spread to other parts of the body. With drug-resistant strains complicating treatment, understanding TB's causes, symptoms, and prevention strategies is essential. Transmission and High-Risk Factors TB is caused by the bacterium Mycobacterium tuberculosis , which spreads through airborne particles when an infected person coughs or sneezes. Individuals with weakened immune systems, such as those with HIV or malnutrition, are at a higher risk. Overcrowded living conditions and poor ventilation also increase the likelihood of transmission, particularly in areas with limited healthcare access. Symptoms of Active and Latent TB Active TB presents with persistent cough, chest pain, fever, night sweats, and weight loss. However, not everyone infected with TB bacteria develops symptoms. Latent TB, where the bacteria remain dormant,

Respiratory infections, ranging from the common cold to more severe illnesses like pneumonia, can significantly impact overall health. Preventing these infections is crucial, especially during flu season or in environments with high transmission rates. Here are the best ways to prevent respiratory infections. Good Hygiene Practices Maintaining good hygiene is one of the most effective ways to prevent respiratory infections. Regular hand washing with soap and water for at least 20 seconds can remove pathogens that cause respiratory illnesses. Using hand sanitizer when soap and water are unavailable is also beneficial. Avoid touching the face, especially the eyes, nose, and mouth, as these are common entry points for viruses and bacteria. Covering the mouth and nose with a tissue or elbow when coughing or sneezing helps prevent the spread of infectious droplets. Vaccination Vaccination is a powerful tool in preventing respiratory infections. Annual flu vaccines can protect against the mo
