Mauritius has been praised as a success story in the containment of the SARS-COV-2. This has been preserved by keeping the borders closed. As the re-opening of the borders are imminent, we carried out a retrospective analysis of how the first wave spread on the island nation. The majority of cases were under the age of 50 years (71%), median age 38 years. 78.0% of cases were asymptomatic, while 20.8% of locally acquired cases were through frontline staff at the border control and at the ministry of Health and Wellness. 40% of the local cases could be traced back to 5 index cases and there was an association between delay in testing and number of infected contacts. 24.2% had no recollection of being in contact with an infected person. The authorities were flexible in identifying high risk population for mass testing and keeping test positivity rate to less than 5%. We therefore identified the areas where further improvement can be done to the existing robust processes: additional training of fronline staff, addressing the concerns of the population so that they do not delay being tested and use of technology for contact tracing of cases.
