Your advice to newcomers in Lobito

If you're living or have lived in Lobito, which advice would you give to new expats?

We namely think of security: should any special precautions be taken (protection systems, areas to be avoided, etc.).

Do you have any particular advice regarding health: malaria is widely spread in Africa, is it also in Angola? Any other precautions to be taken?

Is tapwater safe in Lobito? If not, what means are available on the market to make it drinkable?

These are just examples: if you have any other, please add it!

Your help is appreciated!
