Dengue fever is a mosquito-borne viral illness that is quickly spreading over the globe, with significant death and morbidity rates. Dengue fever is an acute viral infection transmitted by Aedes mosquitos and caused by an RNA virus from the Flaviviridae family. The symptoms might vary from asymptomatic fever to life-threatening complications including hemorrhagic fever and shock. Although dengue virus infections are normally self-limiting, the disease has become a public health concern in tropical and subtropical countries. Dengue fever is a major public health concern owing to its rapid worldwide spread, and its burdens are now unmet due to a lack of accurate therapy and a simple diagnostic approach for the early stages of illness.

Introduction: Infection with any of the 4 dengue virus serotypes results in a diverse range of symptoms, from mild undifferentiated fever to life-threatening hemorrhagic fever and shock. Given that dengue virus infection elicits such a broad range of clinical symptoms, early and accurate laboratory diagnosis is essential for appropriate patient management. So a study was carried out to know its clinical profile, correlation between the laboratory profile and the severity of dengue fever and outcome in dengue patients. Aim: To study the clinical profile, correlation between the laboratory profile and the severity of dengue fever and outcome in dengue patients at tertiary care center. Method: Retrospective Observational study from 1st May 2019 to 31st April 2021. Result: Total 323 patients were studied during 1st May 2019 to 31st April 2021. Most common presentation was fever (100%), most common clinical finding is hepatomegaly (14.2%). All severe dengue infection has platelet count < 50000/cumm. In study of 323 patients 194(60%) of dengue fever,85(26.4%) of DHF GRADE 1,9(2.8%) of DHF GRADE 2 were discharged .13(4%) patients of DSS were expired.22 patients (6.8%) went DAMA. Conclusion: Reliable diagnosis of dengue fever in endemic areas can be done by clinical parameters like presence of nausea, vomiting, pain abdomen and hepatomegaly. Monitoring platelet count, hematocrit and WBC count is very useful for management of dengue cases. Keywords: dengue fever, platelet count, outcome

Dengue fever is a mosquito-borne disease that has rapidly spread throughout the last few decades. Most preventive mechanisms to deal with the disease focus on the eradication of the vector mosquito and vaccination campaigns. However, appropriate mechanisms of response are indispensable to face the consequent events when an outbreak takes place. This study applied single and multiple objective linear programming models to optimize the allocation of patients and additional resources during an epidemic dengue fever outbreak, minimizing the summation of the distance travelled by all patients. An empirical study was set in Ciudad del Este, Paraguay. Data provided by a privately run health insurance cooperative was used to verify the applicability of the models in this study. The results can be used by analysts and decision makers to solve patient allocation problems for providing essential medical care during an epidemic dengue fever outbreak.

The article describes a clinical case of concurrent infectious diseases - dengue hemorrhagic fever and mycoplasma pneumonia in a patient who came back from the area endemic for dengue fever. Further, the patient was diagnosed with clostridial colitis which was the complication. Clinical, laboratory, and radiological parameters used in the diagnosis of diseases were evaluated.

Abstract Background Dengue virus (DENV) is a member of insect vector-borne viruses, and it causes dengue fever. Southeast Asia is the epi-center of dengue fever in the world. The characterization of the virus is essential to identify the transmission and evolution of DENV. Objectives In 2017, there was an outbreak of Dengue virus type 1 (DENV1) in northern Vietnam and the neighboring countries. To identify the genetic character of the outbreak virus in the area, we conducted whole-genome sequencing analysis on the samples positive for the DENV1 along with real-time PCR. Study design In total, 1026 blood samples were collected from patients with suspected dengue fever in Ha Nam and Hai Duong province, nearby areas of the capital of Vietnam. After screening by real-time PCR, 40 of DENV1 positive samples were subjected to whole-genome sequencing, and 28 complete coding sequences were obtained. Results All 28 sequences were genotype I of DENV1, which is dominant in the southeast and East Asian countries. The phylogenetic analysis of the E region showed that they fell into a single cluster with the reported sequences from Vietnam between 2009 and 2016, in which the isolates from other countries are very rare. Our results suggested that the 2017 outbreak in the area was caused by locally circulating viruses.
