COVID-19 Antibody Detecting Rapid Diagnostic Tests (COVID-19 Ab RDTs) are the preferred tool for SARS-CoV-2 seroprevalence studies, particularly in low- and middle-income countries. The present study challenged COVID-19 Ab RDTs with pre-pandemic samples of patients exposed to tropical pathogens. A retrospective study was performed on archived serum (n = 94) and EDTA whole blood (n = 126) samples obtained during 2010–2018 from 196 travelers with malaria (n = 170), schistosomiasis (n = 25) and dengue (n = 25). COVID-19 Ab RDTs were selected based on regulatory approval status, independent evaluation results and detecting antigens. Among 13 COVID-19 Ab RDT products, overall cross-reactivity was 18.5%; cross-reactivity for malaria, schistosomiasis and dengue was 20.3%, 18.1% and 7.5%, respectively. Cross-reactivity for current and recent malaria, malaria antibodies, Plasmodium species and parasite densities was similar. Cross-reactivity among the different RDT products ranged from 2.7% to 48.9% (median value 14.5%). IgM represented 67.9% of cross-reactive test lines. Cross-reactivity was not associated with detecting antigens, patient categories or disease (sub)groups, except for schistosomiasis (two products with ≥60% cross-reactivity). The high cross-reactivity for malaria, schistosomiasis and—to a lesser extent—dengue calls for risk mitigation when using COVID-19 Ab RDTs in co-endemic regions.

In Brazil, American visceral leishmaniasis (AVL) is caused byLeishmania (Leishmania) chagasi and its main vector isLutzomyia longipalpis. Cases of canine visceral leishmaniasis (CVL) in non-endemic areas have been reported over the last few years throughout the country. The objective of this research note is to describe an autochthonous case of CVL that occurred in the municipality of Volta Redonda, state of Rio de Janeiro, an area where the disease is not endemic, alerting veterinarians and the scientific community to the expansion of this important zoonosis and advising veterinary practitioners on how to deal with a suspicion of CVL. Canine visceral leishmaniasis can be misdiagnosed within a broad spectrum of canine diseases based on clinical and laboratory findings. Therefore, knowledge of its clinical manifestations, specific and sensitive laboratory diagnostic tests and parasitological procedures are of the utmost importance for rapid confirmation and notification of a case, thus contributing directly to the control of a focus.

Demographic Features

Visceral leishmaniasis (VL) is a neglected disease. Our retrospective study describes 38 clinical and epidemiological characteristics of VL in patients admitted to a paediatric hospital in Tehran, Iran, who came from different geographical regions, indicating that the disease has spread to most parts of the country. Some 76.3% of the children documented suffered with symptoms of the disease for two months before admission.
