What the similarities and variations of the alphabetic character COVID-19 variant and contagious disease symptoms?

(MENAFN - The Manila Times) There are a number of similarities and differences between the two viruses, including their symptoms, but more or less all of the same is what should be expected for an infectious organism like that. This is why researchers and health experts from the United States have recently focused on how Covid-19 may spread through people either directly or indirectly through contacts that don’t have this disease; because although the exact mechanisms are not known, it is clear that the two diseases have almost the same symptoms in terms of transmission or spread. The most obvious similarity, however, is that both of them are respiratory diseases: SARS-CoV-2, the virus that causes Covid-19, was first detected in March 2019, while other similar coronaviruses have been circulating since last winter, when Chinese authorities announced they were dealing with another contagious virus, referred to as Middle East Respiratory Syndrome (MERS). Both of these, then, are caused by a host and, on the very basis of the same main symptoms that the latter suffers from (or at least most of them), were classified as such. Another apparent similarity is that both of them are caused by a common RNA nucleic acid virus, namely ribonucleocapsid viruses, which belong to the family of non-segmented RNA viruses or “RNA viruses.” An RNA virus infecting the cell of a living being, as these do from time to time, enters into a process of copying itself. To complete its reproduction process, the virus creates new units in the infected cell so, basically, what it does—like any other virus—in order to make new copies of itself—is to produce messenger RNA, also called mRNA. When this messenger RNA is transported, the cell makes a copy of the RNA at the exact same place on the cell membrane. Afterward, the RNA must be translated into proteins by enzymes that would be found in the body—in particular, in the heart, lungs, kidneys, and pancreas. These new units, in turn, would start making new proteins and, then, once they reach different organs, may cause sicknesses. In short, this process is what happens with Coronavirus (SARS-CoV, MERS-CoV, etc.) that enters into cells of animals, humans, and even plants. Both of them are respiratory infections. The main difference between an RNA virus like the one that causes Covid-19 and a conventional RNA virus is that RNA viruses use chemical base pairs, whereas conventional RNA viruses use DNA bases to create new units. Some RNA viruses, though, like those causing the recent outbreak of MERS, use just the same chemicals to replicate themselves. However, since Covid-19 uses the same RNA virus that causes SARS, it will probably replicate in a similar manner as MERS did—with viral particles containing two molecules of DNA. As for MERS, it spread globally, spreading from China to the rest of Asia. This means that there’s no need in looking at the genetic code of the virus anymore, since, by now, if you go back home, most of your genes will be wiped out. On the contrary, the real challenge is figuring out how to find effective measures against the virus that caused SARS, or whether this will be the only pandemic you encounter in the future. Another similarity between covid and sepsis. This can be explained in part to how they are caused and transmitted. Coronaviruses are named after the Latin word that defines how many times they replicate, and they have four main types: classical, beta, gamma, and delta. Classical corona viruses are harmless to humans until they hit one person’s system, where they spread. Beta coronavirs are able to enter a specific human cell; the cell’s receptors recognize the novel coronavirus and bind for a short period before the body’s immune system destroys these particles. Gamma coronaviruses, meanwhile, spread without any harm to normal cells. Finally, delta viruses, which are considered the newest and most dangerous types; they can penetrate normal cells, but unlike other forms of influenza, they enter the brain and cause dementia. All of them have a similar pattern of infection to sepsis. If they are infected into the blood stream or into another organ, they will start producing cytokines, which then trigger changes in the immune system and cause damage to vital bodily tissues like the liver, spleen, kidneys, intestines, lymph nodes, etc. Even if their effects are not severe, some scientists believe that cytokines present during Covid-19 cause damage to these important organs when the immune system starts fighting the infected cells. Other studies point out that this inflammation can contribute to the development of chronic diseases like diabetes, cardiovascular diseases, stroke, and cancer—so you should keep yourself and your loved ones away from infected places. So, even if the two viruses share so much in common, there are certain differences that we know yet.
