South African people are vaccinated with Yellow fever. First, SA is strict in the implementation proof of vaccination in travelers coming in the country. The vaccination card must show vaccination at least ten days prior to travel. This is to prevent reintroduction of the disease to SA people. Second, In the list of Center for Disease Control, South Africa is not included in the countries with an endemic Yellow fever which means that the disease is wiped out if not controlled through vaccination.

36. Breezes are named
77julia77 [94]

The correct answer is - D- for the feature they blow from.

The breezes have all sorts of names, most of which tend to be derived from the feature they flow from. Lot of winds are named after the side of the world that they come from, so there's easterlies, westerlies, northern winds, southern winds. Some are maned after a river, as they flow along side it, like Vardarec. Some may be named after a mountain, or just have a name similar to a mountain, like mountain wind, forest wind, gorski vetrec.

Some winds, on the other hand, have names that describe their force, especially that goes for the strong ones, like bura along the Croatian coast on the Adriatic Sea.
