Spelling

COVID-19 (all capital letters) is the spelling used internationally by scientific and medical professionals and their related organizations, which corresponds with the American convention of capitalizing an acronym such as AIDS or SARS. However, Covid-19 (spelled like a proper noun with an initial capital letter followed by lowercase letters) is the less obtrusive form used by several prominent media, such as The New York Times and The Times of London. And it is not uncommon to see both forms shortened to just COVID or Covid, respectively. The lowercase form covid is considerably less common in edited text.
