<![CDATA[The Surabaya Port Health Office (PHO) Class I is tasked with the disease prevention by detection, response and protection at entrance gates for the sea- and airports and over the state cross-border posts regarding Public Health Emergency of International Concern situation of COVID-19. This analysis aims to assess activities of early warning alert and response system to COVID-19 at Juanda International Airport on January 2020 and provides recommendations to enhance the system in the future. The method used includes interviewing four informants, studying of documents and directing field-observation by following regular activities of PHO representatives, who supervise, inspect General Declarations, distribute, and collect the Health Alert Card (HAC) and monitor body temperature of travelers. The analysis uses a system approach (input, process, output) and a 4M model with modification by adding time, technology and information variables. Activities in the early warning alert and response system of COVID-19 are in accordance with the Preparedness Guidelines by the Indonesian Ministry of Health. The outputs of reported activities have been classified as appropriate. The HAC form is lacking as a source of COVID-19 surveillance with regards to address information, which often being misinterpreted by travelers. It is necessary to add additional questions regarding the destination address of travelers in Indonesia, and to educate on how to fill in a HAC correctly through a completed example form; communication and direction from Surabaya PHO Class I operatives are also necessary so that the effectiveness of HAC can be maximized.]]>
