2020 has been one of the most difficult years for us all, with the rapid spread of the unfortunate COVID-19 pandemic. All of our schedules have changed, and most of our businesses and international travels have stopped. Cities that already experienced previous pandemics/epidemics, such as MERS and SARS, have already been aware of the importance of public health, and managed the current pandemic with less severe out- comes, while it had more tragic results for cities and countries with a weaker public health system and lack of treatment facilities. As IGLUS, we are aware of how important the public health system is for cities to deal with this pandemic. Therefore, through this IGLUS Quarterly issue, we would like to touch upon the spread of COVID-19, and the successes and failures of public health systems in cities.
