“…During the hot and dry months of July and August, there was a marked increase of dengue virus infection (57% and 30% respectively) in contrast to September (13%) where the temperature is a trifle lower (around 39C° with humid weather). This lends credence to studies claiming that low temperatures have a detrimental impact on the rate of development of mosquito life stages as well as viral replication [20]. However, most of Port Sudan's population decides to leave the region between July and August to avoid the extreme temperatures.…”

Objective: Aiming to detect dengue virus antibodies in clinically suspicious patients’ serum, contributing to clinical and laboratory advancements in dengue infection management, exploring the association between a clinico-laboratory makeup and Dengue fever, and enhancing the capacity to anticipate, diagnose, and respond to dengue infection. Methods: At Port Sudan 2015, a descriptive cross-sectional hospital-based study was implemented. Six tertiary care hospitals in Port Sudan were included in the report. Patients who attended assigned hospitals with a suspected dengue infection were investigated. Individuals who are at least 9 months old, residency in study area for at least 7 days, pyrexia with unspecified cause for 2-7 days, thrombocytopenia in malaria negative blood film, as well as ages of 9 months and older considerably involved. Gender, age, residency, and clinical symptoms were used as independent variables while dengue patients posing as the dependent variable. Sample size approximation was created based on previous African community studies. To target respondents, a randomized cluster model was used. Information was gathered through direct interview, as well as questionnaire after signed a consent form. 5ml of venous blood withdraw by a professional nurse from each respondent, then examined for hematological indicators of dengue fever using Sysmex XP-300 Automated Hematology Analyzerand dengue specific IgM antibodies using Panbio® Dengue IgM Capture ELISA. Entering data and analysis of the volunteers’ characteristics, the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA) version 20 was used. Incredibly simple descriptive statistics were used to analyze the laboratory results of the Dengue indicators as well as risk factors. Results: The study involved 83 cases out of 110 that were tested by ELISA at different hospitals in Port Sudan and determined to be diagnosed with the dengue virus.The incidence rate among febrile patients was 75% (68 cases), with DF documented in 80 cases (96%) and DHF in three scenarios (4%). higher prevalence within the (21-30) age category 50/110. (45%).High occurrence rate during July (63 cases) (57%). Fever was the most noticeable clinical feature 79/83(95%, more evident hematological indicators included thrombocytopenia and leucopenia (88%) 97 out of 110 (71%) 78/110 in each event. Most of study subjects were unaware regarding risk factors with exception of transmission mode. Conclusions: Study reported high incidence among suspected febrile participants. Most of patients presented as DF, with greater occurrence among reproductive age group and during July.Thrombocytopenia and leucopenia were more prominent clinical manifestations.With the exception of the mode of transmission, the majority of study respondents were unaware of the risk factors.

BackgroundDengue is an emerging health problem in several coastlines along the Red Sea. The objective of the present work is to elucidate spatial and temporal patterns of dengue transmission in Port Sudan.Methods/FindingsA longitudinal study with three cross-sectional surveys was carried out in upper, middle and lower class neighborhoods, from November 2008 to October 2009. Monthly, entomological surveys were followed by serological surveys in dengue vector-positive houses. Meteorological records were obtained from two weather stations in the city during the same time. Overall, 2825 houses were inspected. Aedes aegypti represented 65% (35,714/54,944) and 68% (2526/3715) of the collected larvae and pupae, respectively. Out of 4640 drinking water containers, 2297 were positive for Ae. aegypti. Clay-pots “Zeirr” followed by plastic barrels were key productive containers for pupae of dengue vector, 63% (n = 3959) and 26% (n = 1651), respectively. A total of 791 blood samples were tested using PanBio Capture/Indirect IgM ELISA. Overall, the sero-prevalence rate of dengue ranged between 3%–8% (41/791), compared to an incidence of 29–40 new cases per 10,000 (193/54886) in the same examined population. Lower and middle class neighborhoods had higher entomological indices compared with upper class ones (p<0.001). Although, dengue incidence rate was significantly lower in the middle and lower class neighborhoods (F = 73.97, d.f. = 2, p<0.001), no difference in IgM prevalence was shown. The city is subject to two transmission peaks in the winter (i.e. November–January), and summer (i.e. June–August). The serological peaks of dengue are preceded by entomological peaks that occur before the onset of winter (November) and summer (March) respectively.ConclusionDengue incidence is heterogeneously distributed across the neighborhoods of Port Sudan and exhibits a bi-cyclic intra-annual pattern. Hence, it should be feasible to carry out timely vector control measures to prevent or reduce dengue transmission.

“…Efforts to improve and/or sustain the city's water supply from the Khor Arbaat catchment area are continuing. A number of water resources assessment studies were conducted in the area (Hussein, 1975;Rhein Rhur, 1989;El Sheikh et al, 2009;Akode and Fadallabi, 1994;Yousif and Abdo, 2003;Taha, 2020;Ali et al, 2013;Mott McDonald, 2016;HydroNova, 2018). These studies show discrepancies in annual aquifer recharge.…”

Hydro-environmental impact of Khor Arbaat Dam, Eastern Sudan

To improve water supply services in Port Sudan City (Sudan), a dam with storage capacity of 16 Mm 3 was established at the upper gorge of the Khor Arbaat catchment area, which generates runoff that contributes to the sedimentation of the dam at an average rate of about 6% annually. At present (2021), the storage capacity of the dam is reduced by 69% of its original design capacity. Without interventions, the dam is expected to continue silting up reducing its capacity to 94% of the original design capacity by year 2044. Although the dam has reduced the amount of runoff that reaches the alluvium aquifer and has caused groundwater recession downstream, the continuous sedimentation and reduction of the dam's storage capacity mean the amount of water that could flow out would gradually increase. Despite its sedimentation, the dam has provided groundwater recharge 1 km upstream of the dam resulting in a rise of 2 m in groundwater level and enabled irrigation of 85% of the arable land. Comparatively, a drop of 1.8 m was observed in groundwater level at 5 km upstream of the dam, with irrigation of only 33% of the arable land. Also, the interception of the base-flow/underflow by the dam, has contributed to the recession of groundwater downstream. These observations can help optimize the use of this resource; by reducing evaporation losses and maximizing the benefit from the reservoir's available storage through the intensification of pumping during the winter period (October-March) when evaporation is comparatively low and reservoir storage can be replenished by winter runoff. Beyond technical fixes (and in the long term), management of water resources in the Khor Arbaat should consider the catchment area as a whole and in an overall framework of Integrated Water Resources Management (IWRM).
