Diet and pre-existing comorbidities are key drivers of the COVID delta virus infection

This study aims to evaluate the nature of the spread of the COVID delta virus through 49 to control it invent a portable device to distinguish it from other flu viruses and propose a chemical drug. A combination of a level of cobalamin thiamine folic acid lipoic acid Fe and Zn played a major role in the COVID delta propagation. Whenever the ratio of chronic diseases in a country did not exceed 30% of different diseases this indicates the COVID delta virus spreading was due to a decrease in Zn level than normal. The most common non-chronic diseases that were related to the spread of the COVID delta virus were gastrointestinal diseases which reached 18% of the different diseases while liver diseases are the most common chronic diseases (12.4%). The proposed device portable COVID-meter could be a strong indicator of distinguishing COVID patients from seasonal cold or flu viruses. Egyptona multi-strains could be a promising antiviral drug to treat COVID patients compared with any vaccines that would be used in the future. People who do not depend on meat or marine mollusks in their diet should reduce wheat flour pastry.
