Yes, a doctor can write articles on matters of public health in the lay press though with some caution. Regulation 7.11 of MCI Code of Ethics Regulations states: “A physician should not contribute to the lay press articles and give interviews regarding diseases and treatments which may have the effect of advertising himself or soliciting practices; but is open to write to the lay press under his own name on matters of public health, hygienic living or to deliver public lectures, give talks on the radio/TV/internet chat for the same purpose and send announcement of the same to lay press.”
