Long Covid in Military Organisations (LoCoMo)

The aim of this research project is to evaluate long-term sequelae of Covid-19 that may have occurred in members of the Swiss Armed Forces. By following up on those army personnel who test positive for SARS-CoV-2 and comparing them with those who test negative, symptoms and sequelae of the infection and impact on life quality can be tracked. The acquired data will also provide insights into the duration of immunity (or lack thereof) after symptomatic and asymptomatic infection and the kinetics of antibody decline in those who test positive. The data collected with an extensive test battery allow for a follow-up on several body systems, including impact on ophthalmological function, on life quality and activities and impact on male fertility. The results of the study will have a societal impact and may also be relevant for other sectors as this cohort is very similar to a large proportion of  health-care workers. Because the proposed test battery is very broad and comprehensive it may also detect so far unknown, long-term sequelae, which might provide insight in the pathophysiology and general understanding of consequences of SARS-CoV-2 infection. In this way, the study results may provide a basis to develop strategies to mitigate SARS-CoV-2 sequelae and allow for preparedness.
