RESUMEN
We report a tick-borne case of severe Crimean-Congo haemorrhagic fever (CCHF) imported into Greece from Bulgaria. The patient presented severe thrombocytopenia, hemophagocytosis, haemodynamic instability, large haematomas and altered mental status. Supportive treatment and ribavirin were administered. Symptoms started one day after the tick was removed; the patient was discharged from the hospital 26 days after symptom onset. No secondary cases were observed. Phylogenetically the CCHF virus strain belongs to clade Europe 1.

Introduction: Long COVID affects millions of individuals worldwide with a wide range of persistent symptoms. Pathogenesis, prevalence and clinical approach of this syndrome remain not well characterized.The aim of the study is the estimation of prevalence of long-COVID and identification of possible risk factors. Patients and Methods: This is an observational prospective study including COVID-19 patients hospitalized at the Department of Infectious Diseases of the University General Hospital of Alexandroupolis (Greece). Eligible COVID-19 patients were interviewed and examined 6, 12 and 18 months after COVID-19 symptoms onset and hospital discharge in order to evaluate the prevalence and consequences of long-COVID symptoms. Results: A total number of 995 patients were included. The median age at discharge was 55 years and 53% of patients were retired. The majority was males (57%). Vaccination against SARS-CoV-2 was completed in 52% (n=517) COVID-19 patients. More than 40% of COVID-19 patients had at least one symptom at 18 months after hospitalization. Intravenous antiviral 0treatment with remdesivir and complete vaccination status were found to lead to lower rates of Long-COVID. Conclusions: More studies in larger patient cohorts are needed in order to identify the underlying biological mechanisms of long-COVID and create effective interventions for prevention and treatment.
