Brief Summary:
This concerns a single-center prospective interventional cohort study. Laboratory-confirmed COVID-19 patients will be asked to donate blood at at least two different timepoints. This will allow us to investigate T and B cell evolutions during the course of infection and recovery. The expected duration of the study is four months or the total duration of the SARS-CoV-2 circulation in Belgium (whichever is shortest).

Primary Outcome Measures :
  1. provide proof-of-concept that (longitudinal) B cell repertoire mining allows identification of emerging virus specific B cell receptor variable regions. [ Time Frame: 4 months ]

Secondary Outcome Measures :
  1. study evolutions in B and T cell repertoires to understand COVID-19 specific immune responses fundamentally. [ Time Frame: every 7 days during hospitalization a bloodsample is taken ]
  2. clinical and epidemiological description of UZA hospitalized COVID-19 patients [ Time Frame: at hospitalization ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Sampling Method:   Non-Probability Sample
Study Population
The study will be conducted in an in-patient hospital setting. Patients will be recruited at UZA, where SARS-CoV-2 infected individuals might present. Patients with (mild) respiratory complaints and suspected risk of having contracted SARS-CoV-2 (risk contact with confirmed case, travel history to endemic area) will be tested and isolated in awaiting laboratory SARS-CoV-2 test results. In case of mild respiratory complaints, people will be discharged immediately for home isolation; while patients in need for hospital care will be hospital-admitted (in isolation rooms). If SARS-CoV-2 test results return positive, these hospitalized patients will be asked to participate in this study.

Inclusion Criteria:

  • laboratory confirmed COVID-19 acute infection
  • be older than 18 years of age
  • be hospitalized at the UZA
  • willing and able to provide written informed consent by the participant or its legal representative (for instance in case of medical incapacitation)

Exclusion Criteria:

  • younger than 18 years old
  • Ambulatory patients
