Dr Mohammed Alvis Zibran

Dr Alvis Zibran

Currently, Alvis Zibran is working as a Senior Medical-Officer at Sigatoka Subdivisional Hospital in the Western Division of Fiji. Prior to this, he was working as the Area Medical-Officer at Lomawai Health Centre for 5 years. Alvis graduated with MBBS in 2011 from Fiji National University and did his internship at Lautoka Hospital in 2012 , after which he was posted to Lomawai H/C for his peripheral posting.

In addition to his current role, Alvis is working with the Wellness Unit of Fiji (under the supervision of Dr Tukana) as the Chairperson of the National PEN Core Working Group. His motivation for promoting health comes from his first hand experience in dealing with premature non-communicable diseases in terms of morbidity and mortality whereby the young people (below age 40 years) are either suffering or dying too early due to NCDs.

Alvis believes that tackling this NCD crisis in Fiji needs a lifestyle intervention rather than banking merely on drugs! Healthy eating, exercising, quitting smoke/alcohol and reducing stress are the major factors that can reduce the NCD burden. This is his my motto.
