Is it Safe?
To put things in perspective, it is safer than the United States.
However, be sensible. For example, don't walk alone in certain places late at night.
If you left valuables unattended, most likely they would be stolen. However, very few people would threaten you with violence to take your valuables.
Is it Corrupt?
For local people doing business, the system is very corrupt. Those with money can do whatever they want, but the poor are not given a fair go. People see the poverty. Most don't understand, the real problem is a corrupt system.
But this does not normally affect tourists. Most tourists are not aware of what really goes on.
There is corruption in most poor countries.
Is it Unhealthy (disease).
If you are a sensible person, the main thing to be concerned about, is drinking contaminated water, or eating food prepared with contaminated water and getting diarrhea. Be sensible with what you eat and drink.
Every country has some sickness and disease. In places where there is a lot of poverty, it tends to be worse than in places where people have everything they need.
