Thank you very much for the question.
I think for the most part people are hitchhiking. In my research, I can give you very specific examples of people who walked two to three days to access health care. I spoke to such people. I have met them. Many people are using very unsafe methods because they have no other option to be able to travel across cities, depending on where they are.
I have encountered people who literally walk for multiple days on a highway to access health services and other services.
