Both Amy and Mikey are correct.

Explanation:

Attention to possible health problems and early medical attention to health issues are essential to maintain the proper physical and mental functioning of human beings, especially children and adolescents, who may be more prone to problems.

For this reason, we can say that Amy is correct when she says that paying close attention to health risk factors and warning signs can improve teenagers' emotional and mental health. Likewise, Mikey is correct when he says that seeking medical care for a child with a cough and skin rash can lead to early detection of a health problem and ultimately improve the child's health.
