which challenges do countries face in limiting the spread of communicable diseases? lack of available healthy food increase of worldwide travel decrease of available clean water increase in migration of infected animals
Answer
Answer:
B. increase of worldwide travel
Brief Explanations:
World - wide travel spreads diseases faster as infected individuals can quickly move across regions, making it hard to contain communicable diseases. Lack of healthy food and clean water are more related to general health and non - communicable disease factors in some cases. The migration of infected animals is a factor but not as significant as human travel in terms of the global spread of communicable diseases among countries.
