NCT04323904
Hantavirus disease are zoonotic infections and remain a clinical challenge with globally increasing incidence and multiple serious outbreak situations in Europe within the last years. Hantavirus disease encompasses two clinical syndromes, hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS) caused by Old World and New World hantaviruses, respectively. Depending on the causative Old World hantavirus species, clinical course of HFRS can vary from mild to moderate to severe. At present, there is no specific therapy available for hantavirus disease. As the clinical course of hantavirus disease is dependent on the causing viral pathogen and as there worrisome hints that clinical course HFRS and HCPS overlap, further studies with regard to the disease course are mandatory. Furthermore, the examination of attributable mortality and costs of hantavirus disease will need to be studied on a multinational basis and therefore HantaReg will particularly use a matched case control design.
NCT00533767
This study is designed to evaluate the transmission of hantavirus in Chile. It is an observational study that will look at close household contacts of people who have been diagnosed with hantavirus infections that result in a serious illness to see how frequently they become infected. Subjects who enroll in the study will donate samples of body fluids (e.g., blood, saliva, stool, urine, respiratory and vaginal secretions) to allow the researchers to see if hantavirus is present in those fluids and if so, how much. Subjects will also be interviewed to identify household conditions that may be associated with transmission. Up to 76 index cases (people who are first diagnosed with hantavirus cadiopulmonary illness) and up to 140 of their close contacts will be enrolled. Subjects will be followed for about 6 weeks.
