Practical approach to a patient with a fever after travelling to the tropics.
By 2030, an estimated 2 billion international tourist trips are expected annually worldwide, with citizens of Poland as important contributors. Illness rates among returnees from developing regions range between 43% and 79%. Properly diagnosing fever in these travelers is vital due to potentially serious implications. ⋯ Other significant diseases include chikungunya, Zika, typhoid fever, amebic liver abscess, and occasionally viral hemorrhagic fevers. SARS‑CoV‑2 and influenza viruses are crucial pathogens as well. An in‑depth assessment of the travel history, combined with knowledge on tropical diseases, are key to the diagnostic process, and algorithms may be helpful in selecting appropriate tests and treatment methods.

Syndromic surveillance often relies on patients presenting to healthcare. Community cohorts, although more challenging to recruit, could provide additional population-wide insights, particularly with SARS-CoV-2 co-circulating with other respiratory viruses. ⋯ Symptom profiles varied little by aetiology, making distinguishing SARS-CoV-2, influenza and RSV using symptoms challenging. Most symptoms were not explained by these viruses, indicating the importance of other pathogens in syndromic surveillance. Influenza vaccination was associated with lower rates of community influenza test positivity.

COVID-19 Outcome and Tobacco Product Use: Case-Control and Retrospective Cohort Studies Using Nationwide Samples.
Conflicting evidence exists regarding the association between smoking and the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We investigated the association between combustible cigarette (CC) smoking, noncombustible tobacco product (NCTP) use, and the use of any tobacco product with various coronavirus disease 2019 (COVID-19) outcomes. ⋯ Current CC smokers and current users of any tobacco product showed reduced risk of SARS-CoV-2 infection and COVID-19-related hospitalization. It remains uncertain whether these relationships are causal.
