There's been an effort to depict loss of taste and smell as something new, and a clear indicator of covid. Pure hokum. I lost most of my sense of smell and taste to the flu five years ago, and didn't get it back for over a year. It was kind of bizarre. I could smell my own shit and urine, but they had a completely different odor than before. This was quite concerning, of course, so I researched it and found it to be a not uncommon side effect of flu. Some people never get it back.
I don't know for a fact, but I think there was probably some sort of bioweapon at large for a couple months in 2020. It led to a blood disease that often involved leaking into the lungs and severe breathing problems. But at least since early summer 2020 it's been obvious that the flu, pneumonia, any type of respiratory illness, any type of malady at all was to be chalked up as covid to keep the scamdemic going. The bogus PCR test served as a foundation for the fraud.
