The long-term impacts of coronavirus on our cities are difficult to predict, but one thing is certain: cities won’t die. Diseases have been hugely influential in shaping our cities, history shows. Cities represent continuity regardless of crises – they endure, adapt and grow. Silvia Tavares and Nicholas Stevens write in The Conversation that urban designers and planners have a long-term role in ensuring urban life is healthy. To fight infectious diseases, cities need well-ventilated urban spaces with good access to sunlight. The design of these spaces, and public open spaces in particular, promotes different levels of sociability. Some spaces congregate community and are highly social. Others may act as urban retreats where people seek peace with their coffee and book. How urban spaces perform during disease outbreaks now also demands our close attention.
