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.
Why does a person infected with HIV become more likely to develop tuberculosis?: HIV destroys white blood cells, so the immune system is weakened and cannot fight other pathogens.
Why is measles described as a communicable disease?: It is caused by a pathogen (a virus) and can be passed or spread from person to person.
True or false? Obesity is a communicable disease.: False. Obesity is non-communicable — it is not caused by a pathogen and is not spread from person to person.
