Question

write differences between communicable and non-communicable diseases

Answer 1

What Are Communicable DiseasesCommunicable diseasesare spread from person to person or from animal to person. Thespread or transfer can happen through the air, through contact with contaminated surfaces, or through direct contact with blood, feces, or other bodily fluids. Acoldisan example of a communicable disease (a cold is the general term given to a viral infection of theupper respiratory tract).This is probably why those airline passengers mentioned at the start of this lesson were wearing masks. Viruses in the respiratory passageways can easily be coughed or even just breathed out. So, if the inconsiderate cold-carrier sitting next to you on the plane coughs, virusesare spewed into your vicinity. You breathe, and suddenly those viruses have found a new respiratory tract to call home (yours!). That cold has now been passed from one infected person to another uninfected person, spreading thecommunicable disease.You can probably identify other communicable diseases. If a diseaseis caused by viruses, bacteria, fungi, or protozoa it's likely, although not always, communicable. Rabies, HIV, malaria, influenza, and athlete's foot are just a few examples of communicable diseases you may be familiar with.What Are Noncommunicable DiseasesAnon-communicable disease(NCD) is a medical condition or disease that is not caused by infectious agents (non-infectiousornon-transmissible). NCDs can refer to chronic diseases which last for long periods of time and progress slowly. Sometimes, NCDs result in rapid deaths such as seen in certain diseases suchasautoimmune diseases,heart diseases,stroke,cancers,diabetes,chronic kidney disease,osteoporosis,Alzheimer's disease,cataracts, and others. While sometimes referred to as synonymous with "chronic diseases", NCDs are distinguished only by their non-infectious cause, not necessarily by their duration, though Some chronic diseases of long duration, such asHIV/AIDS, may caused byinfections. Chronic diseases requirechronic care managementas do all diseases that are slow to develop and of long duration.
