The cost-effective options in combating COVID-19.

Sunil J. Wimalawansa

The first wave of COVID-19 rapidly spread worldwide during the first half of 2020. Since August 2020, the second wave of COVID-19 has been rampaging across most countries, coinciding with the initial winter period. A third wave may likely occur during the late spring of 2021. These peaks coincided with annual winter flu season in countries located in northern and the southern-most latitudes, during their respective winter periods. Recently identified COVID-19 mutant has rapidly spread into many countries in the world, faster than the original COVID-19. An acquisition of gene mutation in spike-protein, this mutant developed increased infectiousness but less lethal than the original virus.
