What disease is rare today?

Answer:
That depends on how developed a country is. Rickets, once common in the USA is virtually unheard of now, but is still a severe problem in certain places. Two diseaases that have just about been totally eradicated are smallpox and polio, but polio seems to be on the rise, again, in underdeveloped areas.
