Domestic travel bans can increase cases: University of Chicago study

According to a study done by the university using data from India and five other countries, using domestic travel bans to control COVID-19 infections may be inadvisable. It found that imposing travel bans can counter-intuitively increase the total spread of coronavirus disease, creating a ‘lose-lose situation’. The national lockdown in the first wave trapped millions of migrants inside big cities like Mumbai that were fast-growing coronavirus hotspots.
