Heart Disease
Heart disease encompasses various conditions that affect the heart's functioning. It includes coronary artery disease, heart rhythm problems (arrhythmias), and congenital heart defects, among others.
Stroke
A stroke occurs when blood flow to the brain is disrupted, leading to cell death. It can result from a blocked artery (ischemic stroke) or bleeding in the brain (hemorrhagic stroke).

Respiratory diseases affect the lungs and other parts of the respiratory system. They can range from acute infections to chronic conditions that impair lung function.
Chronic Obstructive Pulmonary Disease (COPD)
COPD is a progressive lung disease that makes it difficult to breathe. It typically includes chronic bronchitis and emphysema, often caused by long-term exposure to harmful gases or particulate matter.
Asthma
Asthma is a chronic inflammatory condition that causes the airways to narrow and swell, leading to wheezing, shortness of breath, and coughing. It can be triggered by various factors, including allergens and respiratory infections.
Pneumonia
Pneumonia is an infection that inflames the air sacs in one or both lungs, causing symptoms such as fever, cough, and difficulty breathing. It can be caused by bacteria, viruses, or fungi.

Infectious diseases are caused by pathogenic microorganisms such as bacteria, viruses, parasites, or fungi. They can spread from person to person through direct or indirect contact.
Influenza (Flu)
Influenza, commonly known as the flu, is a contagious respiratory illness caused by influenza viruses. It can range from mild to severe and can lead to complications such as pneumonia, especially in high-risk groups.
HIV/AIDS
Human immunodeficiency virus (HIV) weakens the immune system, making it susceptible to various infections and diseases. Acquired immunodeficiency syndrome (AIDS) is the most advanced stage of HIV infection, characterized by severe immune deficiency.
Tuberculosis (TB)
Tuberculosis is a bacterial infection that primarily affects the lungs but can also affect other parts of the body. It spreads through the air when an infected person coughs or sneezes, making it highly contagious.
