"Mucus-producing goblet cells and ciliated cells in the nose had the highest levels of both these [genes], of all cells in the airways," first author Waradon Sungnak from the Wellcome Sanger Institute said in a statement. "This makes these cells the most likely initial infection route for the virus."

I recall back in grammar school, the annual school fair always had a plentiful supply of them. They were hand knit or crocheted and sold as 'nose warmers', to keep noses from freezing or dribbling snot during the cold winter months.
