COVID-19 Symptoms: Researchers from the University of Barcelona-Spain, Instituto de Salud Carlos III-Spain, University of Múrcia-Spain, University of Hawai-U.S. and University of Oxford-UK have in a new study concluded that nasal dryness could be an early warning sign of COVID-19 disease.


 
One of the entry routes of SARS-CoV-2 is the nasal epithelium. Although mounting evidence suggests the presence of olfactory dysfunction, and even anosmia, in individuals with COVID-19, it is not clear whether these patients also suffer from other “nasal” symptoms that may influence their olfaction.
 
A group of 35 patients with COVID-19 (and a control group matched in gender and age) were surveyed about the presence of a variety of nasal symptoms that may be associated to drastic perturbations experienced in the nasal cavity (e.g., “excessive dryness” and/or a continual sensation of having had a “nasal douche”).
 
The study team used a cross-sectional, retrospective survey, targeted at the general population by means of non-quoted, non-random, snowball sampling.
 
Symptoms were assessed with absence/presence responses. The possible association between two continuously distributed latent variables from categorical variables was estimated by means of polychoric correlations
