Health & Disease Flashcards

All 4 cards in this deck

How does the World Health Organization (WHO) define health?: A state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity.
True or false? Beriberi, caused by a lack of vitamin B1, is a communicable disease.: False. It is non-communicable: it is not spread from person to person and is not caused by a pathogen.
Why can having one disease make a person more likely to catch another?: The first disease can damage or weaken the immune system, so the body is less able to defend against other pathogens.
e.g. people with HIV are more likely to develop TB.
What is the difference between a communicable and a non-communicable disease?: A communicable disease is caused by a pathogen and can be spread between individuals; a non-communicable disease cannot be passed from one person to another.
