Interventions

Study AOTHER

Study A: collection of data of clinical outcomes and features of SARS-CoV-2 infection. Demographical, clinical, microbiological, laboratory, epidemiological and hospital-associated data will be analyzed. For this study part, only patients with a visit at the University Hospital Basel will be included in order to access patient charts.

SARSCoV-infected patients (cases)non-SARS-CoV-2 infected patients (control)
Study BOTHER

Study B: collection of epidemiological surveillance data to describe the epidemiology of the SARS-CoV-2 outbreak. The epidemic transmission of Influenza viruses in the City of Basel serves as an important reference to identify similarities and differences to the pandemic SARS-CoV-2 situation. In addition data collected during the Influenza projects - in particular data on statistical blocks of the city, e.g. population density, income and living space will be re-used. Already collected and stored samples such as serum and respiratory material (leftover material) will be (re-) used.

SARSCoV-infected patients (cases)
Study COTHER

Study C: data collection for viral evolution. Respiratory materials and matching blood and tissue materials will be used to perform whole genome sequencing to study pathogen evolution between hosts as well as in-host evolution. No additional material will be collected.

SARSCoV-infected patients (cases)
Study DOTHER

Study D: collection of safety and efficacy data of different treatment modalities. Currently the following treatments are considered as part of the treatment: 1. Lopinavir/Ritonavir 2. Hydroxychloroquine 3. Tocilizumab 4. Eculizumab 5. Ruxolitinib 6. Remdesivir 7. Treatment with convalescent plasma blood count, blood chemistry and pulmonary function test (collected on a routine basis during hospitalization and in the outpatient setting).

Study Population

SARSCoV- 2 infected patients and non-SARS-CoV-2 infected patients with or without other respiratory viruses with residency in Basel (Basel-Stadt, Riehen, and Bettingen)

You may qualify if:

  • Study A: All patients being tested for SARS-CoV-2 at the University Hospital Basel (USB) and with residency in Basel (Basel-Stadt, Riehen, and Bettingen) will be included for clinical outcome evaluation. All age groups will be included. In addition, non-clinical data such as epidemiological and hospital associated data of all people living in Basel but not necessarily tested at the University Hospital Basel will be included
  • Study B: Epidemiological data and serum and respiratory samples across all Age groups from people with residency in Basel (Basel-Stadt, Riehen, and Bettingen) with and without confirmed SARS-CoV-2 infection will be included
  • Study C: SARS-CoV-2 viral genome analysis will be conducted from all patients tested positive for SARS-CoV-2 genome by NAT at the University Hospital Basel and living in Basel (Basel-Stadt, Riehen, and Bettingen). In addition, viral genome analysis will be conducted from all people tested positive for SARS-CoV-2 genome by NAT living in Basel by the mentioned study partners. All Age groups will be included.
  • Patients with cleared SARS-CoV-2 infection coming for plasma donation will be included to describe immunological response after successfully cleared infection.

You may not qualify if:

  • documented refusal of the general consent or an available/known written or oral statement against Research
  • People, who are tested at the USB, with residency outside of Basel (Basel-Stadt, Riehen, and Bettingen)
