How Coronavirus kills its victims

Niyi Akinnaso


THIS essay has two apparently contradictory messages. On the one hand, it affirms that the coronavirus illness, in any other case referred to as COVID-19, just isn’t essentially a demise sentence. There are international locations, similar to Uganda and Vietnam, which have recorded no deaths to date, regardless of confirmed instances of coronavirus. Though over 500 deaths have been recorded in Nigeria, practically double that quantity has recovered from the illness. However that is just one facet of the story.

Then again, the coronavirus illness is a demise bomb for sure people who’re contaminated. That’s why over half a billion individuals to date have died of the virus worldwide. True, individuals with pre-existing circumstances, similar to coronary heart, lung, or kidney illness, are at better danger of demise, the information to date present that the virus can kill nearly anyone. But, there may be neither an authorized remedy nor a vaccine towards the virus as of as we speak.

Within the seek for remedy or vaccine, researchers have studied the behaviour of the virus within the final six months, whereas others have studied chosen autopsies of lifeless victims, with a view to perceive why so many individuals have died of the virus. Such data is important with a view to develop an efficient remedy or vaccine.

Three findings stand out. First, there isn’t a doubt that the coronavirus is able to laying its victims to waste as it could trigger huge devastation of varied organs. When the virus enters by the mouth, nostril, or eyes, its first house is the higher respiratory tract. The virus binds to explicit receptors and start to copy itself. The receptors, technically referred to as Ace-2, assist in regulating blood stress. They’re frequent within the higher respiratory tract however are additionally discovered within the lungs, coronary heart, kidney, gut, blood vessels, and even the mind.

Analysis exhibits that the virus might migrate from this preliminary binding to the receptors within the different organs listed above. The presence of the virus in these receptors, particularly these within the blood lining, often is the motive for the unusually extreme clotting of the blood and why sufferers with hypertension and diabetes are at very excessive danger. Worse nonetheless, Ace-2 receptors might assist the virus attain so far as the mind, the place it binds to the Ace-2 receptors within the mind. This will likely nicely clarify among the bizzare signs of the virus, similar to lack of style and odor, erratic respiration, irregular heartbeat, seizures, stroke, and even nervous breakdown.

Second, it has been discovered that it’s not the virus alone, which kills its victims. The physique’s defence mechanism deployed in combating the virus can overreact and trigger demise. Right here, in a nutshell, is the way it occurs. When a pathogen (virus, bacterium, or another microorganism) enters the physique, immune cells are drawn to the purpose of an infection to destroy the intruder. A protein, technically referred to as cytokine, is launched by the physique to coordinate the physique’s response to the intruder. Within the course of, extra white blood cells are produced, which rush to the purpose of an infection to battle it. Irritation follows as a part of the method of therapeutic the physique from the an infection.

Sadly, nonetheless, the physique’s immune system can overreact, resulting in a “cytokine storm”, whereby extra immune cells are produced, resulting in hyper-inflammation. Within the course of, the physique is destroyed together with the virus. The affected person might get higher and even check detrimental for the virus, whereas nonetheless in hospital. Nevertheless, a number of organs might have been destroyed and blood stress might drop to harmful ranges. When a affected person will get to this degree, demise typically follows.

A 3rd main discovering helps to elucidate why people fluctuate of their response to coronavirus an infection, that’s, why some die whereas others survive, even in outdated age. First, though people share the identical genes, the methods wherein the genes are regulated within the physique differ from individual to individual. Subsequently, many victims of coronavirus might climate the storm and survive the an infection, whereas others succumb to it, relying on their genetic make-up. Genetic variation may clarify why Ace-2 receptors are expressed in a different way in numerous organ tissues, relying on the person.

As indicated earlier, the underlying situation of the varied organs can also be a essential issue. That’s why these with preexisting circumstances are at a lot better danger. Nevertheless, because the above findings and the information on coronavirus deaths present, there have been individuals with no preexisting situation, who however nonetheless died of the virus. Not simply outdated individuals, however younger of us as nicely.

It’s pure for readers of this essay to ask: What’s the therapy or what’s the perfect therapy? The easy reality is that, as of as we speak, there isn’t a remedy for coronavirus. Every case is commonly managed because it comes and because the affected person’s situation deteriorates. This isn’t to say that there are not any therapy choices. The bare reality is that no choice has been discovered to fully stop demise in all sufferers and even within the majority of sufferers.

That leaves you and me with the non-pharmaceutical choice of following the WHO-sanctioned pointers, supplied by the Nigeria Centre for Illness Management and echoed repeatedly by the Presidential Process Power on COVID 19:

  • Keep at house, if you’re not working or on important service.
  • Put on face masks, in the event you exit. You need to even put on one at house, if you’re coughing or sneezing or if somebody in your family is.
  • Preserve bodily distancing of no less than six ft (ese bata mefa) everytime you exit.
  • Keep away from touching your mouth, nostril, or eyes.
  • Wash your palms incessantly with cleaning soap or alcohol-based sanitizer.
  • Predominant good total hygiene always, together with often wiping door handles, distant controls, and your telephones, with disinfectant.

As well as, the oga amongst us should be sure that their aides, drivers, cooks, gardeners, and different dependents or co-workers comply with these pointers. They have to work with leaders of their major or secondary communities to teach individuals in regards to the existence and prevalence of this virus and to allow them to know that it could kill.

For now, following these mitigation measures is our greatest wager. To place it in one other method, the perfect remedy for coronavirus for now’s NOT to catch the illness in any respect.
