“…Nigeria, Ghana, and DRC have a sickle cell trait prevalence between 20% and 30% while some parts of Uganda have a prevalence as high as 45% ( Regional Committee for Africa, 2006 ). Angola has a SCD prevalence rate of approximately 2% ( Brito et al ., 2022 ). Gabon has an estimated SCD prevalence rate of 1.8% ( Minto’o et al ., 2022 ) and Cameroon has an estimated prevalence rate of 0.6% ( Alima Yanda et al ., 2017 ).…”

“…Prevalence estimates of sickle cell trait for Cameroon, Democratic Republic of Congo (DRC), Gabon, Ghana and Nigeria are between 20% and 30% but in Uganda are estimated up to 45% ( Regional Committee for Africa, 2006 ). In Angola, the prevalence of SCD is about 2%, with sickle cell carriers reaching 21% of the population ( Brito et al ., 2022 ). Recent estimates for Tanzania found a disease prevalence of 1.2% and trait prevalence of 20.3% using blood spot samples from children born to mothers with human immunodeficiency virus ( Ambrose et al ., 2020 ), however this is likely to be an underestimate due to sub-optimal screening.…”

The United Nations Council Assembly recognized sickle cell disease (SCD) as a global public health problem due to its increasing burden, particularly in sub-Saharan Africa. To raise awareness, a resolution was adopted, designating June 19th as SCD awareness day. However, the impact of this awareness day on online health information seeking behaviour (OHISB) in African countries is not well understood, especially in Nigeria, Ghana and Uganda where SCD prevalence is high. To assess the impact, the study used Google Trends data as a measure of OHISB for SCD. The analysis covered the 60 days before the awareness day, the awareness day itself, and the 60 days afterward. Time series analysis was conducted using joinpoint regression to identify significant changes in OHISB trends. The results indicated that the impact of the Sickle Cell Awareness Day on OHISB varied across African countries and did not consistently inspire significant changes in information seeking behaviour. This suggests the need for more targeted awareness campaigns to improve public knowledge of SCD in Africa. It also highlights the importance of revising the current awareness day or creating alternative health awareness initiatives that adopt a long-term approach and address the specific health needs of the African population. Furthermore, due to limitations in using Google Trends data in some African countries with insufficient data, future research should explore other sources of internet data or conduct surveys to gain a more comprehensive understanding of the impact of the Sickle Cell Awareness Day on OHISB in Africa.
