Robust infrastructure prevails despite the population density that the district in which a person lives may have if we speak in terms of vulnerability to COVID-19, as a new study suggests.
Thanks to an exhaustive analysis of data from the first months of the pandemic (until April 4 and June 27, 2020), the researchers found that the demographic structure of a population (age, social and economic class, access to resources) is much more influential than population density.
Crowding is not density
The data comes from Iran’s AC-19 app, which tracks positive cases and deaths by geographic location. The researchers assessed whether certain variables affected infection rates in the 22 districts and around 8.6 million people in Tehran.
The study also notes that what causes the spread of infectious diseases during a pandemic is overcrowding, which can occur even in low-density districts.
While a person less likely to know or follow public health guidelines or more likely to use public transport may be at greater risk of contracting the disease, the researchers found no statistically significant difference in urban districts. low income.
However, the study has some drawbacks. The main thing is the availability and accuracy of the data. The pandemic evolved so rapidly in the first few months that surveillance may not give the full picture.
