Baby moving to accra

I hope you don't mind me asking you.  My husband and two children ( 3 months and 2 years old ) are considering moving to Accra for a job my husband has been offer.
I am very concerned about the health of my children, specially my infant baby who is 3 months old.
I am mostly worried about Malaria, polio, yellow fever and others, do you live there, did you move your family and baby there.
We live in Denver, USA, life is good and happy here, I don't want to move my children all the way over there and just be stress and worried all the time. 
Would you please just give me some comments about your life there and your baby.
I want to experience life there if I move, I don't want to be stress or super worried about my children getting sick.
I am also worried about getting decent food, specially milk and yogurt and meats and etc.
Hope you can please help me.

Ghana isn't the healthiest place to live but if you take the right precautions and make sure all the vaccinations etc are done then they should be protected. Malaria is a constant problem but using repellent at night and in the morning and sleeping under nets will help reduce the chance of being bitten.
You can get good food in Accra but it isn't the same if you are outside so it depends where you are going to be based.
I hope someone with children will also answer you.

Thank you so much for your response.  My 3 months old will not have all of his vaccinations, you don't get all your vaccines until you are 2 years old I beleive.  My 2 year old should be ok.
Do you know if there is meningitis and polio still in Accra.
We will be located in Accra, Cantoments I beleive.
Can we get fresh pasteurized caws milk.
How about meat?
thank you
