Background: Invasive Staphylococcus aureus (iSA) and group A Streptococcus (iGAS) infections impose significant health burdens globally. Both bacteria commonly cause skin and soft tissue infection (SSTI), which can result in invasive disease. Understanding of iSA and iGAS incidence remains limited in settings with high SSTI burden.

Methods: Prospective surveillance for admissions with iSA or iGAS was conducted at the referral hospital in Fiji's Northern Division over 48 weeks between July 2018-June 2019.

Results: There were 55 admissions for iSA and 15 for iGAS, (incidence; 45.2 and 12.3 per 100,000 person-years respectively). Highest incidence was found in those aged ≥65 years s (59.6 per 100,000 person-years for both). Indigenous Fijians (iTaukei) had higher iSA incidence (71.1 per 100,000 person-years) compared to other ethnicities (incidence risk ratio 9.7, 95% CI 3.5-36.9). SSTIs were found in the majority of iSA (75%) and iGAS (53.3%) cases. Thirteen out of the 14 iGAS strains isolated belonged to emm-cluster D (n = 5) or E (n = 8). Case fatality rate was high for iSA (10.9%) and iGAS (33.3%).

Conclusions: The incidence of iSA and iGAS in Fiji is very high. SSTIs are common clinical foci for iSA and iGAS. Both diseases carry a substantial risk of death. Improved control strategies are needed to reduce the burden of these diseases in Fiji.

Hospital admissions for skin and soft tissue infections in a population with endemic scabies: A prospective study in Fiji, 2018-2019.

Scabies is an important predisposing factor for impetigo but its role in more serious skin and soft tissue infections (SSTIs) is not well understood. Information is limited on incidence of SSTIs in the presence of endemic scabies. We conducted a prospective study of hospital admissions for SSTIs in the Northern Division of Fiji (population: 131,914). Prospective surveillance for admissions with impetigo, abscess, cellulitis, wound infection, pyomyositis, necrotizing fasciitis, infected scabies, and crusted scabies was conducted at the Division's referral hospital between 2018 to 2019. Information was collected on demographic characteristics, clinical features, microbiology, treatment and outcomes. Over the study period, 788 SSTI admissions were recorded corresponding to a population incidence 647 per 100,000 person-years (95%CI 571-660). Incidence was highest at the extremes of age with peak incidence in children aged <5 years (908 per 100,000) and those aged ≥65 years (1127 per 100,000). Incidence was 1.7 times higher among the Indigenous Fijian population (753 per 100,000) compared to other ethnicities (442 per 100,000). Overall case fatality rate was 3.3%, and 10.8% for those aged ≥65 years. Scabies was diagnosed concurrently in 7.6% of all patients and in 24.6% of admitted children <5 years. There is a very high burden of hospital admissions for SSTIs in Fiji compared to high-income settings especially among the youngest, oldest and indigenous population which is concordant with scabies and impetigo distribution in this population. Our findings highlight the need for strategies to reduce the burden of SSTIs in Fiji and similar settings.
