Acute viral hemorrhagic fever, known as Lassa, was first identified in 1969 in the town of Lassa, Borno State, Nigeria. Lassa is located in the valley of the Yeseram River near the southern end of Lake Chad. Three weeks after being infected with Lassa virus, patients feel sick. Pathogenesis is associated with immunosuppression, uncontrolled viral replication and host response, and infection does not cause lytic damage. Lassa viruses disable the host\\\'s immune system in several ways. The typical endosomal trafficking pathway essential for innate immune system recognition is bypassed. The most useful way for diagnosis is polymerase chain reaction (PCR) from blood. Sensitivity was reported as 79 % on the first day of hospitalization, increasing to 100 % on the third day. One of the most effective approaches to contain the spread of Lassa fever in endemic areas is to improve community cleanliness.

Hypertension is a public health problem which has cut across all spheres of life and walks of life. From the literature review, the researcher has found that most hypertensive patients are less engaged in healthy behaviours because of knowledge deficit. The literature reviews also indicated that gender, age, level of education, lifestyle, and compliance to treatment regimen had significant association with healthy behaviours in patients with hypertension.

Acute leukemia is the most common childhood malignancy, accounting for nearly 35% of all childhood cancers. Acute myeloid leukemia (AML) accounts for 15-20% of childhood acute leukemias. The majority of AML cases are de novo, but a minority may present as secondary malignancies. AML is a highly heterogeneous disease, the diagnosis of which involves morphology, immunophenotyping, cytochemistry, and diagnostic analyzes involving leukemic blasts derived from peripheral blood or bone marrow exhibiting cytogenic and molecular characteristics. Includes combinations. By identifying recurrent genetic mutations, it is now possible to improve individual prognosis and guide treatment management. Pediatric acute myeloid leukemia (AML) is a heterogeneous disease that requires a multifaceted therapeutic approach. Although the outcomes of low-risk AML have improved significantly over the past decades, high-risk AML continues to be associated with poor prognosis. Recent advances in molecular diagnostics, risk stratification, and supportive care have helped improve outcomes in childhood AML.

Co-infection with both HIV and malaria presents a complex medical challenge, particularly concerning hematocrit variations that often result in anemia in affected individuals. This comprehensive review aims to explore and synthesize existing literature to elucidate the multifaceted nature of hematocrit alterations observed in HIV patients concurrently infected with malaria. The pathophysiological mechanisms contributing to hematocrit variations in this co-infected population involve a complex interplay between the immunosuppressive effects of HIV and the hemolytic nature of malaria parasites. Understanding these mechanisms is crucial for developing targeted interventions. Diagnostic challenges abound due to overlapping symptoms and limitations in conventional diagnostic tools, necessitating the exploration of more advanced diagnostic methodologies to accurately assess and monitor hematocrit levels in co-infected individuals. The clinical implications of hematocrit variations in this context extend beyond mere anemia, impacting disease severity, treatment response, and the overall prognosis of affected patients. Anemia complicates therapeutic interventions, potentially affecting the efficacy of antiretroviral and antimalarial treatments. Persistent anemia in co-infected individuals increases vulnerability to opportunistic infections and compromises treatment outcomes, underscoring the necessity for comprehensive management strategies. These strategies encompass a holistic approach involving antiretroviral therapies, antimalarial drugs, nutritional support, and potential interventions such as blood transfusions in severe cases. In conclusion, this review consolidates current knowledge, emphasizing the need for further research to elucidate the nuances of hematocrit variations in HIV patients co-infected with malaria. Improved understanding, enhanced diagnostic modalities, and optimized management strategies are crucial to mitigate the impact of anemia and improve outcomes in this vulnerable patient population.

Early Infant Diagnosis (EID) plays a crucial role in ensuring a HIV-free start for newborns born to HIV-positive mothers. This review highlights the significance of EID in pediatric HIV care, emphasizing its role in timely identification of HIV infection, prevention of morbidity and mortality, facilitation of Prevention of Mother-to-Child Transmission (PMTCT) programs, reduction of HIV transmission, and promotion of long-term health outcomes. Despite its importance, EID faces challenges such as limited access to testing services and logistical constraints. Addressing these challenges requires strengthening health systems and leveraging innovative approaches to expand access to EID services. Investing in EID programs is essential for achieving global HIV elimination targets and advancing towards an AIDS-free generation.
