Background The risk factors for scrub typhus in Vietnam remain *** typhus caused by Orientia tsutsugamushi often presents as an undifferentiated febrile illness and remains under appreciated due to the limited availability of diagnostic *** tropical rickettsial illness is increasingly recognized as an important cause of non-malaria acute undifferentiated fever in *** study aimed to investigate behavioural and ecological related risk factors of scrub typhus to prevent this potentially life-threatening disease in *** We conducted a clinical hospital-based active surveillance study,and a retrospective residence-enrolment date-age-matched case–control study in Khanh Hoa province,Vietnam,from August 2018 to March *** examinations,polymerase chain reaction and enzyme-linked immunosorbent assay IgM tests were applied to define cases and *** enrolled participants filled out a questionnaire including demographic socio-economic status,personal behaviors/protective equipment,habitat connections,land use,and possible exposure to the *** conditional logistic regression was used to define the scrub typhus associated risk *** We identified 44 confirmed cases and matched them with 152 *** cases and controls,the largest age group was the 41–50 years old and males accounted for 61.4%and 42.8%,*** were similarities in demographic characteristics between the two groups,with the exception of *** factors were significantly associated with acquisition of scrub typhus,including sitting/laying directly on household floor[adjusted OR(aOR)=4.9,95%CI:1.6–15.1,P=0.006],household with poor sanitation/conditions(aOR=7.9,95%CI:1.9–32.9,P=0.005),workplace environment with risk(aOR=3.0,95%CI:1.2–7.6,P=0.020),always observing mice around home(aOR=3.7,95%CI:1.4–9.9,P=0.008),and use of personal protective equipment in the field(aOR=0.4,95%CI:0.1–1.1,P=0.076).Conclusions Ecological

HIV/AIDS is still an important public health issue in Vietnam and other developing countries. In Vietnam, Community-based organizations (CBOs) were officially considered as the key partners to approach vulnerable groups at high risks of HIV infection since 2010. Funds for HIV/AIDS prevention and control are facing difficulties due to rapid reduction by international organizations, while domestic funding has not yet met the demand, especially funding for prevention and communication activities. Our study aimed to assess the fundraising capacity of several CBOs in Ho Chi minh City, Vietnam and analyze the challenges that they are facing now and in future in their work of HIV/AIDS management for community. The 03 typical and representative CBOs (G3VN, Smile and Strong Ladies) were chosen in our cross-sectional descriptive study. The electronic questionnaire was about fundraising reports over 3 years (2017-2019), organization structure (staff, mission, strategies) and the advantages and disadvantages in fundraising. Funds received over the year increased in total, but unstable in each projects. To have more funds, CBOs must invest time and money to have professional staff in fundraising and writing proposals. To meet requirement and survive, some CBO shifted to social enterprises and faced many difficulties in laws when being treated like profit companies. In Vietnam context, the key challenges which affect the role of funding are including: 1) Legal status;2) Small scale;3) Capacity of fundraising (finding calls, writing competence proposals);4) Fewer funds on HIV/AIDS. In future, we should pay attention in scaling up and building fundraising capacity for CBOs in order to help them in applying for international funds in community projects or even in HIV/AIDS research for CBOs, social enterprises in the context of funds for nation-level phased out of Vietnam.

Probabilistic assessment of drought plays an important role in providing valuable information for evaluating water resources systems under drought conditions, and bivariate copulas are effective and efficient for the probabilistic assessment of drought based on joint distributions and/or joint return periods of drought characteristics. In this study, hydrological drought events and their characteristics (including duration and severity) in the tien Yen River Basin of Quang Ninh province are detected using the Standardized Streamflow Index (SSFI). The BB8Copula is selected as the best-fit copula for hydrological drought duration and severity. Joint probabilities and joint return periods of drought duration and severity in the cases “and” and “or” are calculated based on the BB8Copula, which are employed for drought assessment. The results show that the drought events with 1-season or cross-quarter duration were more popular than others;joint probabilities and joint return periods of the detected drought events from 1962 to 2009, ranged from 0.2% to 92.2% and from 0.782 years to 315.414 years, respectively, in the case “and”, and ranged from 3.8% to 99.6% and from 0.724 years to 18.785 years, respectively, in the case “or”.
