Brief Summary
A prospective, longitudinal cohort study designed to follow-up on 500 Swiss military personnel who tested in 2020 for SARS-CoV-2 (regardless of whether positive or negative, but with a known test result). Participants are invited to undergo an intensive test battery to evaluate if they suffer COVID-19 sequelae. The testing will include evaluation of several body systems (cardio-vascular, pulmonary, neurological, ophthalmological, psychological and general) and male fertility in a voluntary subgroup. Immune markers and SARS-CoV-2 reinfection rates will also be evaluated. The study hypothesis is that SARS-CoV-2 infection causes a multi-system disease with sequelae detectable in a significant proportion of army recruits after infection with SARS-CoV-2.

Outcome Measures
Primary Outcomes (1)
to longitudinally follow-up on a cohort of 500 military who tested either positive or negative for SARS-CoV-2 in early 2020 for possible sequelae, one year post infection
The primary endpoint is the occurrence of SARS-CoV-2 infection sequelae in a longitudinally follow-up cohort of a total of 500 military who tested either positive or negative for SARS-CoV-2 in early 2020.
One year
Secondary Outcomes (1)
Outcomes from components of the test battery
One year
Study Arms (3)
Symptomatic
167 symptomatic Swiss army recruits who tested positive for SARS-CoV-2 in 2020
Asymptomatic
167 asymptomatic Swiss army recruits who tested positive for SARS-CoV-2 in 2020
No evidence of infection
167 Swiss army recruits with no evidence of infection (who also were tested for SARS-CoV-2 in 2020)
Interventions
Eligibility Criteria
The project population is Swiss army recruits who were tested for SARS-CoV-2 in 2020 (regardless of whether they tested positive or negative, but with a known test result).
