What items does the medical examination for immigrants in the United States include?

There are four aspects in American immigration physical examination (medicine). The first aspect: immigration physical examination, sometimes asking people to take off their clothes. The physical examination also includes an assessment of mental condition. The second aspect is "tuberculin reaction test" (tuberculosis and the like). But only people over two years old do this test. The third aspect is "serum examination". Only people over the age of fifteen have blood tests to check whether there are "HIV" and "syphilis". If the doctor suspects that people under the age of 14 may be infected with these viruses, the doctor can check this. The fourth aspect: it is to fight "immune vaccine." If immigrants can show proof that they have been vaccinated before, they don't have to spend money to get vaccinated again. Therefore, the proof of previous vaccination should be properly preserved for future use.
