I have a MBBS, MPH degree and I presently working as a Surveillance Medical Officer with WHO. Its job description includes but not limited to "Provided technical guidance and build capacity of the government and non-government staff to sustain polio-free status as per the polio eradication and end game strategic plan. Facilitated trainings for AFP Surveillance, supplementary immunization for polio rounds, strengthening of routine immunization, outbreak response to any wild, vaccine derived or Sabin-like type 2 polioviruses. Facilitated activities related to intensification of routine immunization, measles elimination and rubella control, outbreak response and surveillance of vaccine preventable diseases (VPDs)." More or less like an epidemiologist. Should this come under 3111 (Specialist Physician) or 41404 (Health Policy researchers, consultants and program officers)?
