Abstract
The COVID-19 positive cases are increasing at an alarming rate across the world. On the contrary, the morbidity and mortality are showing decreasing trend as time progresses. The most intriguing part is the rise in asymptomatic Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) positive cases in the population, which made us speculate some kind of gradual development of immunity in the population. To date, no attention has been given to the accumulation of killed/inactivated/degenerated SARS-CoV-2 associated molecular particle patterns (SAMPPs). In this paper, we introduced the concept of SAMMPs and its existence on inanimate objects is quite conceivable due to the size of SARS-CoV-2 and exuberant shedding of the virus in respiratory secretions. SAMPPs can come into the contact with mucosal surfaces and thereof associated antigen-presenting dendritic cells. Thus, we hypothesized the existence of SAMPPs mediated the development of immunity against SARS-CoV-2 infection, which has caused an increase in the incidence rate of asymptomatic cases and a decrease in mortality rate. To understand the existence of SAMPPs associated natural immunity against SARS-CoV-2, future population based serological testing are recommended to investigate serum antibody levels against various molecular particles associated with SAMPPs.
