communicable disease
Communicable Disease:
Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host. Infections may range in severity from asymptomatic (without symptoms) to severe and fatal. The term infection does not have the same meaning as infectious disease because some infections do not cause illness in a host. Disease causing biologic agents include viruses, bacteria, fungi, protozoa, multi-cellular parasites, and aberrant proteins known as prions. Transmission of these biologic agents can occur in a variety of ways, including direct physical contact with an infectious person, consuming contaminated foods or beverages, contact with contaminated body fluids, contact with contaminated inanimate objects, airborne (inhalation), or being bitten by an infected insect or tick. Some disease agents can be transmitted from animals to humans, and some of these agents can be transmitted in more than one way.
Non-Communicable Disease:
A non-communicable disease, or NCD, is a medical condition or disease, which by definition is non-infectious and non-transmissible among people.
Tuberculosis:
Signs and Symptoms:
A bad cough that lasts 3 weeks or longer.
Pain in the chest.
Coughing up blood or sputum (phlegm from deep inside the lungs)
Weakness or fatigue.
Weight loss.
No appetite.
Chills.
Fever.
Causes:
Tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air. This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings. Although tuberculosis is contagious, it's not easy to catch. You're much more likely to get tuberculosis from someone you live with or work with than from a stranger. Most people with active TB who've had appropriate drug treatment
