Abstract
An extreme Saharan dust storm (named Godzilla) arrived at the Caribbean region in June 2020, deteriorating the air quality to hazardous levels and unhealthy conditions for sensitive groups of people. Our main objective was to
characterize populations at risk for Saharan dust by analyzing distribution and levels of dust events in Puerto Rico, and by
conducting an online survey to assess community perceptions on Saharan dust health effects. Three daily satellite aerosols
products from 2013 to 2020 were retrieved from the Visible Infrared Imaging Radiometer Suite over Puerto Rico to better
understand the patterns, frequency, and seasonality of aerosols. The atmospheric results indicated that extreme values
( > 99th) of big size aerosols (e.g., Sahara dust) were observed over Puerto Rico on 22 June 2020. A total of 1504 qualified
people participated in the survey during the summer of 2020, and it was analyzed with descriptive statistics, frequency analysis, and chi-square tests. 51% of the survey participants were on the age group of 25–44 years old, and 65% of the participants had at least one preexisting health condition (respiratory diseases 27%; cardiovascular diseases 28%). Nearly 90% of
the participants indicated that Saharan dust affected the health status of both the respondents and their family members.
Irritation of eyes (22%), nose (24%), and throat (23%), as well as breathing difficulties (10%), were the most common
symptoms reported. Understanding patients’ health profiles associated with Saharan dust is essential before developing
public health strategies to minimize exacerbation of health conditions in Puerto Rico.
