Modern public health practice requires multidisciplinary teams of public health workers and professionals. Teams might include epidemiologists, biostatisticians, physician assistants, public health nurses, midwives, medical microbiologists, economists, sociologists, geneticists, data managers, and physicians. Depending on the need, environmental health officers or public health inspectors, bioethicists, and even veterinarians, gender experts, or sexual and reproductive health specialists might be called on
