Issue：Papua New Guinea is striving to achieve the minimum core requirements under the International Health Regulations in surveillance and outbreak response, and has experienced challenges in the availability and distribution of health professionals.Context：Since mid-2009, a large cholera outbreak spread across lowland regions of the country and has been associated with more than 15 500 notifications at a case fatality ratio of 3.2%. The outbreak placed significant pressure on clinical and public health services.Action：We describe some of the challenges to cholera preparedness and response in this human resource-limited setting, the strategies used to ensure effective cholera management and lessons learnt.Outcome：Cholera task forces were useful to establish a clear system of leadership and accountability for cholera outbreak response and ensure efficiencies in each technical area. Cholera outbreak preparedness and response was strongest when human resource and health systems functioned well before the outbreak. Communication relied on coordination of existing networks and methods for empowering local leaders and villagers to modify behaviours of the population.Discussion：In line with the national health emergencies plan, the successes of human resource strategies during the cholera outbreak should be built upon through emergency exercises, especially in non-affected provinces. Population needs for all public health professionals involved in health emergency preparedness and response should be mapped, and planning should be implemented to increase the numbers in relevant areas. Human resource planning should be integrated with health emergency planning. It is essential to maintain and strengthen the human resource capacities and experiences gained during the cholera outbreak to ensure a more effective response to the next health emergency.

With the significant reformation of the health care system in China, medical edu-cation has also been adjusted rapidly in order to meet the needs of health services and development of medical and health undertakings. However, as a result of the adjustment of medical education system and the different schooling system in different regions around the country, medical education system and academic degree in China can hardly be comparedaround the world, and the education institutions such as universities in foreign countries can't understand clearly our country's medical education system and degree very well. Based on the medical education theory and practice of Australia, this paper de-scribes and analyses the difference of medical education system between the two countries, so as to provide some idea on perfecting the medical educationtralning model in China as well as lay a founda-tion for the comparison between Chinese medical education system and mature systems of foreign countriessuch as Australia.

Objective: Open-source data from online news reports and informal sources may provide information about outbreaks before official notification. This study aims to evaluate the use of open-source data from the epidemic observatory, EpiWATCH, to identify the early signals of pneumonia of unknown cause as a proxy for COVID-19 in Indonesia. Methods: Using open-source data on pneumonia of unknown cause in Indonesia between 1 November 2019 and 31 March 2020 (extracted from EpiWATCH, an open-source epidemic observatory), a descriptive analysis was performed to identify the trend of pneumonia of unknown cause in Indonesia before official notification of COVID-19 cases. Results: A rise in reports of pneumonia of unknown cause was identified in Indonesia, starting from late January 2020. There were 304 reported cases of pneumonia of unknown cause, 30 of which occurred before the identification of the first COVID-19 cases on 2 March 2020. The early signals of pneumonia of unknown cause in Indonesia may indicate possible unrecognized circulation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) before official detection. Discussion: Open-source data may provide rapid, unvalidated information for early detection of outbreaks. Although unvalidated, such information may be used to supplement or trigger investigation and testing. As EpiWATCH sources global information, this methodology can be repeated for other countries within the Western Pacific Region, and for other diseases.

Objective: During the COVID-19 pandemic, face mask wearing was mandated in Port Moresby in July 2020, but compliance was observed to be low. We aimed to determine the frequency of face mask wearing by the general public in Papua New Guinea under the mask mandate. Methods: To estimate compliance with the mandate, we analysed photographs of people gathering in Port Moresby published between 29 September and 29 October 2020. Photo-epidemiology was performed on the 40 photographs that met pre-defined selection criteria for inclusion in our study. Results: Among the total of 445 fully visible photographed faces, 53 (11.9%) were observed wearing a face mask over mouth and nose. Complete non-compliance (no faces wearing masks) was observed in 19 (4.3%) photographs. Physical distancing was observed in 10% of the 40 photographs. Mask compliance in indoor settings (16.4%) was higher than that observed in outdoor settings (9.8%), and this difference was statistically significant (P <0.05). Mask compliance was observed in 8.9% of large-sized gatherings (>30 people), 12.7% of medium-sized gatherings (11–30 people) and 25.0% of small-sized gatherings (4–10 people; photographs with <4 people were excluded from analysis). Discussion: We found very low population compliance with face mask mandates in Papua New Guinea during the pre-vaccine pandemic period. Individuals without face coverings and non-compliant with physical distancing guidelines are considered to be in a high-risk category for COVID-19 transmission particularly in medium- and large-sized gatherings. A new strategy to enforce public health mandates is required and should be clearly promoted to the public.
