There is no variant called Delmicron, indian media is misquoting the guy who meant that there are two seperate variants responsible for waves in US/UK.I was wrong. Delmicron is combination of both Omicron and Delta variants. It has spike proteins of both Omicron and Delta. This is what I could gather from some of Indian news sites.
Yes, we should be even more cautious. Vaccination plus social distancing and masks is the way to go. Avoid crowds whenever you can.
