BACKGROUND Tick-borne encephalitis (TBE) is an arboviral disease that is focally endemic in parts of Europe and Asia. TBE cases among US travellers are rare, with previous reports of only six cases among civilian travellers through 2009 and nine military-related cases through 2020. A TBE vaccine was licenced in the USA in August 2021. Understanding TBE epidemiology and risks among US travellers can help with the counselling of travellers going to TBE-endemic areas. METHODS Diagnostic testing for...

We identified Naegleria fowleri as the aetiologic agent from cerebrospinal fluid (CSF) of a patient with a travel history to Karachi. We demonstrate the benefit of metagenomics-based rapid diagnosis of primary amoebic meningoencephalitis (PAM) when routine clinical tests fail to provide a definitive diagnosis. We reconstructed the N. fowleri genome.
A healthy young woman from Cameroon was addressed to the tropical medicine consultation of the University Hospitals of Geneva to investigate an asymptomatic eosinophilia of 1.22 G/l and a history of "eye worms"during childhood. Direct microscopic observation found viable microfilariae and the stained blood smear confirmed Loa loa species.
We report a case of Strongyloides stercoralis suspected CNS dissemination in a Brazilian woman previously misdiagnosed with eosinophilic granulomatosis with polyangiitis and consequently treated with immunosuppressant therapies. This case highlights the urgent need for a broader awareness of NTDs among all specialists working in high-income countries with sustained migration flows.
This sero-survey describes the level and time-trend of antibodies elicited by BNT162b2 COVID-19 vaccine up to 6 months. A strong seroconversion was seen at 30-day serology, with persistence of anti-SARS-CoV-2 S-RBD IgG through 6 months from vaccination. However, the level of vaccine-induced antibodies started to decrease from the second month.
Although malaria is one of the differential diagnoses among travelers to endemic area, delayed hemolysis following malaria treatment with artemisinin-derivative drugs during travel should be aware. We highlight the clinical perspective for clinicians to consider this clinical phenomenon to detect any delayed hemolytic event early and prevent potentially serious consequences.
