Blood samples from newborns are collected by capillary or venous sampling and absorbed on blotting paper (Guthrie) at the same time as those for other neonatal screenings. The dried papers are sent to the inter-regional laboratory in Lille, for further processing. In Saint-Laurent-du-Maroni, in order to reduce the proportion of people lost to follow-up, a double screening is carried out and the results are returned before discharge from the maternity hospital.

Sickle cell genotypes include 493 SS (60%), 302 SC (37%) and 28 S-Beta-thalassemia (3%). The incidence of sickle cell disease was 1/213, 95% CI [1/236-1/204], and that of heterozygotes 1/10, IC 95% [1/12-1/8]. The majority of these children (52%) were from the Maroni region. The delay between screening and test results was 7 days. Only pathological results (homozygous, heterozygous) were communicated to parents and/or the attending physician by post. These data confirm the upward trend in the number of children screened for sickle cell disease in French Guiana. Data from screening campaigns organized by the Drepaguyane association have enabled to describe the distribution of the various abnormal hemoglobin fractions, and to confirm that HbS is more frequent in Western French Guiana.

The study reveals the improvement in the organization of sickle cell disease management in French Guiana between 1992, when screening was introduced, and the present day.

The caustic product was caustic soda in 59%. The average quantity of product ingested was 5 ml (2 ml to 20 ml). The average consultation time was 3 days (3 hours to 15 days). Clinically, dysphagia was the most functional sign, represented by 13 cases, or 76%.

In addition, inaccessibility to care, especially during the critical period of the Covid-19 pandemic, greatly reduced vaccination coverage rates. In Benin, several vaccines are included in the Expanded Programme on Immunization or are administered as part of routine immunization. However, cases of non-compliance with the vaccine and persistent flaccid paralysis are still recorded in the commune of Ouidah in southern Benin.

All the households were included. The survey regarded children under 5 for whom a vaccination record was presented.

An univariate analysis followed by a multivariate analysis was performed by using a logistic regression model to identify the variables that influence vaccine completeness. Spatial description of vaccine completeness was performed using the kriging method using ArcGIS 10.8 mapping software. Results.

Of the 238 children with an immunization card, 20.6% were fully immunized for their age. All children received Baccille Calmette Guérin vaccine at birth. Since poliomyelitis, pentavalent, pneumococcal conjugate, and rotavirus are three-dose vaccines, the percentage of children who received these vaccines decreased as the number of doses increased: 96.6%, 88.2%, 78.1% and 72.3% for the four doses of polio respectively. According to 53.4% of the respondents the reception at the vaccination site was poor, and according to 70.3% of them waiting time for vaccination sessions was long.

It covered a 24-month period from October 2020 to October 2022. It included all patients with major sickle cell syndrome seen in clinical haematology and with a positive thick drop/parasite density, whatever the parasitaemia value. For each patient, a blood count was performed on the Sysmex XT 4000i machine, supplemented by a smear study after staining with May-Grunwald Giemsa.

Non-adherence to antihypertensive medication were mostly noted in widows, patients without occupation, those with low education and no health insurance.
