The main reason why Zimbabweans are coming to South Africa at large is that the situation in their country is bad. There is dire poverty in Zimbabwe. Most of the things that they get for free in South Africa are paid for in Zimbabwe. For example, there is free medical care here and in Zimbabwe, it is very hard to get a free service in a hospital. In their economy, there is excessive inflation, and even basic things are very expensive.
The way things are in Zimbabwe, even the price of condoms is so high that people are no longer affording them. A condom is a very essential thing because it protects people from diseases and also unplanned pregnancy. According to a report by IOL news, Zimbabwean sex workers are resorting to using bread packets as condoms because they cannot afford real condoms. The price of a condom pack is equivalent to the monthly salary of a domestic worker in Zimbabwe. See the pictures below:
After this was posted, South Africans were left in shock. However, some are concerned that the very same situation might happen in South Africa because of the constant increase in fuel prices. Some people even suggested that the South African government must send some of the condoms to Zimbabwe because there are condoms that are just expiring in South African hospitals without being used. So there you have it.
Condoms are very assential, Without them, diseases will spread quickly and there will be a high rate of pregnancy, resulting in overpopulation in the country. This will also affect South Africans because there have been so many cases of Zimbabwean pregnant women who were caught trying to cross the border so that they could give birth in South African hospitals since Zimbabwean health services are poor. So they will come to South Africa at large.
