Factors associated with delay in seeking healthcare for imported malaria: a retrospective study in a French hospital.

BACKGROUND: Delayed treatment is associated with a higher risk of severe malaria. In malaria-endemic areas, the main factors associated with delay in seeking healthcare are low educational level and traditional beliefs. In imported malaria, determinants of delay in seeking healthcare are currently unknown. METHODS: We studied all patients presenting with malaria, from 1 January 2017 to 14 February 2022, in the hospital of Melun, France. Demographic and medical data were recorded for all patients, and socio-professional data were recorded for a subgroup of hospitalized adults. Relative-risks and 95% confidence intervals were determined using univariate analysis by cross-tabulation. RESULTS: There were 234 patients included, all travelling from Africa. Among them, 218 (93%) were infected with P. falciparum, 77 (33%) had severe malaria, 26 (11%) were <18 years old and 81 were included during the SARS-CoV-2 pandemic. There were 135 hospitalized adults (58% of all patients). The median time to hospital admission (THA) , defined by the period from onset of symptoms to arrival at hospital, was 3 days (IQR = 2-5). A THA ≥3 days tended to be more frequent in travellers visiting friends and relatives (VFR; RR = 1.44, 95% CI = [1.0-2.05], P = 0.06), while it was less frequent in children and teenagers (RR = 0.58, 95% CI = [0.39-0.84], P = 0.01). Gender, African background, unemployment, living alone and absence of referring physician were not associated with delay in seeking healthcare. Consulting during the SARS-CoV-2 pandemic was neither associated with a longer THA nor with a higher rate of severe malaria. CONCLUSION: In contrast to an endemic area, socio-economic factors did not impact on delay in seeking healthcare in imported malaria. Prevention should focus on VFR subjects, who tend to consult later than other travellers.

Epidemiology and Clinical Presentation of Children Hospitalized with SARS-CoV-2 Infection in Suburbs of Paris.

Understanding the clinical presentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and prognosis in children is a major issue. Children often present mild symptoms, and some severe forms require paediatric intensive care, with in some cases a fatal prognosis. Our aim was to identify the epidemiological characteristics, clinical presentation, and prognosis of children with coronavirus disease 2019 (Covid-19) hospitalized in Paris suburb hospitals. In this prospective, observational, multicentre study, we included children hospitalized in paediatric departments of Paris suburb hospitals from 23 March 2020 to 10 May 2020, during the national lockdown in France with confirmed SARS-CoV-2 infection (positive RNA test on a nasopharyngeal swab) or highly suspected infection (clinical, biological, and/or radiological data features suggestive for SARS-CoV-2 infection). A total of 192 children were included for confirmed (n = 157) or highly suspected (n = 35) SARS-CoV-2 infection. The median age was one year old (interquartile range 0.125-11) with a sex ratio 1.3:1. Fever was recorded in 147 (76.6%) children and considered poorly tolerated in 29 (15.1%). The symptoms ranged from rhinorrhoea (34.4%) and gastrointestinal (35.5%) to respiratory distress (25%). Only 10 (5.2%) children had anosmia and five (2.6%) had chest pain. An underlying condition was identified in almost 30% of the children in our study. Overall, 24 (12.5%) children were admitted to paediatric intensive care units, 12 required mechanical ventilation, and three died. For children in Paris suburbs, most cases of Covid-19 showed mild or moderate clinical expression. However, one-eighth of children were admitted to paediatric intensive care units and three died.
