Pacific Regional:

• The risk of importation of measles cases, the susceptibility of the population, as well as the risk of a local or largescale measles outbreak and corresponding need for partner support, continuously monitored in all other PICs. The risk of importation of cases in PICs remains moderate, as inter- and intra-island movement will start in January 2020, after the holiday season.

• WHO is deploying staff to several PICs with elevated risks related to measles and other infectious hazards, focusing on joint action planning and health security system strengthening. For the period of January to March 2020, these efforts will include Kiribati, the Commonwealth of the Northern Mariana Islands (CNMI), the Republic of the Marshall Islands (RMI), the Federated States of Micronesia (FSM) and Vanuatu.

• Availability of vaccines is currently monitored by UNICEF and WHO (Table 3) and a contingency plan is in place in case of additional demand.
