A total of 132 HBSS admissions were recorded (63 in 2021 and 69 in 2022), with a male predominance (54.5%), while the majority aged between 20 and 29 years (55.3%). Vaso-occlusive crisis (VOC) was the most common morbidity (80.6%). Seasonal variations in admissions occurred, which peaked during rainy season months (May, June). The percentage of in-hospital mortality was 5.3% and mortality was seen to be significantly higher among stroke cases (50.0%) than other HBSS morbidities (p = 0.046). Seasonal patterns influenced HBSS morbidity, with VOCs predominating especially during the rainy season.
Oghide et al. (2026) studied this question.
