Revealed Comparative Advantage (RCA) of Asean 5 Countries Watermelon in the Global Market

Watermelon Citrullus Lanatus (Thunb) is an important commercial fruit crop in ASEAN. One way to improve economic growth is through trade and comparative advantage. There are very some researches regarding with comparative advantage of watermelon trade in ASEAN. The purpose of this article is to determine the comparative advantage of watermelon trade in five ASEAN member countries. This article uses secondary data only. Watermelon trade data covering the six years period 2014-2019 were obtained from the United Nations Commodity Trade Statistics Database. This article applies the original index of the revealed comparative advantage (RCA) and revealed symmetric comparative advantage (RSCA) to find out the level of comparative advantage of watermelon commodity. Results show that Lao Peoples Democratic Republic, Myanmar and Viet Nam have a comparative advantage of watermelon trade in the global market. This study suggests that ASEAN 5 member nations should try to maintain its comparative advantage of watermelon exports in the international market

Outcomes of Community-Based Systematic Screening of Household Contacts of Patients with Multidrug-Resistant Tuberculosis in Myanmar

Screening of household contacts of patients with multidrug-resistant tuberculosis (MDR-TB) is a crucial active TB case-finding intervention. Before 2016, this intervention had not been implemented in Myanmar, a country with a high MDR-TB burden. In 2016, a community-based screening of household contacts of MDR-TB patients using a systematic TB-screening algorithm (symptom screening and chest radiography followed by sputum smear microscopy and Xpert-MTB/RIF assays) was implemented in 33 townships in Myanmar. We assessed the implementation of this intervention, how well the screening algorithm was followed, and the yield of active TB. Data collected between April 2016 and March 2017 were analyzed using logistic and log-binomial regression. Of 620 household contacts of 210 MDR-TB patients enrolled for screening, 620 (100%) underwent TB symptom screening and 505 (81%) underwent chest radiography. Of 240 (39%) symptomatic household contacts, 71 (30%) were not further screened according to the algorithm. Children aged <15 years were less likely to follow the algorithm. Twenty-four contacts were diagnosed with active TB, including two rifampicin- resistant cases (yield of active TB = 3.9%, 95% CI: 2.3%–6.5%). The highest yield was found among children aged <5 years (10.0%, 95% CI: 3.6%–24.7%). Household contact screening should be strengthened, continued, and scaled up for all MDR-TB patients in Myanmar
