How immune system responds to a coronavirus attack?

Humans immunity system has major parts and they all work together to balance the body and it's all activity. they also called white guard of the body like (WBC). at this time you can do yoga. like energy healing technique against  Coronavirus a deadly human enmity virus which is known as the novel corona has affected over 2 million globally and killed more than 100,000 people. 


immunity system and virus attack


Human is now shifted to a self-quarantine as our goverment has a lockdown country and they are creating a crazy relationship with Indian women just for time pass. this is the time according to the survey we must improve our immunity system we have designed an immune-boosting food list. natural food for a better health system. these viruses are not different from influenza viruses, or even the coronaviruses responsible for the common cold, attack the body. Therefore, the immune system has a predictable response. It is the degree to which this response is tolerated by the body that determines mortality rates.


How does the immune system respond to a coronavirus attack?




A cascade of viral particles enters the body through the nose, eyes or mount. Breathing carries some of these particles to the lower respiratory tract where the spike proteins of the coronavirus, acting as a key, lock into epithelial cells that line the respiratory tract as well as those in the air sacs in the lungs. that's why it is advised to use an N95 pollution mask and telling us to sanitize your hand

SARS-CoV-2 is able to stay undetected longer than many flu or coronaviruses and its spike proteins are able to gain entry by unlocking the ACE2 protein on the lung cells. Once in, they hijack the cell’s machinery, replicate and multiply and infect adjoining cells. Like the defining ACE2 proteins on the epithelial cells, viruses to have a tell-tale signature on their surface called antigens spotting these is what kicks the immune system into action by producing antibodies.



The signals they generate trigger another class of chemicals- cytokines and chemokines – and they alert the immune system to send an array of different kinds of cells that specialize in destroying viral particles. However, these cytokines and chemokines trigger inflammation in the cells. many of, use a normal mask to protect himself from getting infected but do you know which mask is safe against covid-10 and who should bear a mask. In the nose and upper regions of the respiratory system, this inflammation produces mucus and a runny nose to trap viral particles and prevent their ingress. This also triggers sneezes to expel them.

Hence the sinuses are inflamed we get a headache and the general stuffiness that we associate with a cold. When a gland called the hypothalamus is inflamed, it results in a fever.


However, in the case of SARS-COV-2, the virus seems better at penetrating deeper. The inflation triggers a fluid build- up in the lungs. The fluids also contain the residue of a host of specialized cells- including T cells – that carpet bomb and damage many of the body’s own cells as well as the viral particles. 


It is in expelling this fluid that a dry cough, characteristic of the coronavirus infection, begins. As more air sacs are infected, the lungs find it harder to perform their core job of extracting oxygen from the air, and eventually, this aggravates breathlessness.


Why are some infections mild and others life-threatening?


Depending on the degree of infection in the lungs, the inflammation, and the fluid build-up can lead to pneumonia. 

A patient will require hospitalization to treat the breathlessness and ventilator support to artificially provide oxygen if the condition worsens.

However, massive levels of cytokines can cause extensive lung damage and a condition called Acute respiratory distress Syndrome. The unsustainable cytokine storm can cause organ damage far beyond the lungs and spread to the kidneys as well as the heart. 

If the infection is acute, it can also lead to a depletion of the frontline white blood corpuscles tasked with fighting the infection and making the body vulnerable to other secondary infections, which may lead to death.


How have the elderly reacted to virus?


The elderly, especially those with existing  conditions such as diabetes and cardiovascular disease, already have an inherent malfunctioning in the immune system. 

In many ways, it is the reaction of the body is trying to combat the virus that ends up being suicidal.

The different kinds of drugs, whether it is hydroxychloroquine or anti-HIV drugs, deployed to treat serious COVID-19 infection, also work in some way to moderate the immune-system’s aggressive defense.



Mortality statistics globally suggest that men are twice more likely than women to succumb to a COVID-19 infection. 

This follows from studies that show women, on average, have a better-regulated immune response than men in pathogenic infections. 

Estrogen is said to be an immune-system modulator and the ability to deal with a pregnancy – which also begins as a foreign body growing within – primes women to better deal with infections say, experts.


What about children?


The response of the immune system is in many ways a mystery. For instance, sofar, there have been few deaths reported in children from COVID-19. 

Given that children’s immunity systems are still maturing and learning to adapt to a galaxy of infectious agents, why they seem to be relatively better protected from severe COVID-19 the disease is not known.


Will a vaccine help? 


There are several vaccine candidates but it will be months before we know if any of them will be viable. The bulk is aimed at developing a molecular construct, in some cases a weakened version of the coronavirus, that mimics the antigens o the virus and triggers an appropriate antibody response. 

There are complications – such as an antibody-dependent enhancement – in which insufficient levels of antibodies can actually end up aggravating an infection as in the case of dengue. However, in the case of COVID-19, that’s a problem for another day.



conclusion:


coronavirus lockdown has changed our life our thinking and overall our everything would change just because of this deadly virus. as per the above information, our immune system reacts fast against infection so the government has launched many suggestions for people's safety. 

as they launched aarogya setu app to monitor your health remotely. hope you will understand the nature of this deadly virus mostly housewife, labor is in danger.

vaccine and other relief management services are running fast to relieve common people, here we also have to understand the situation and without losing hope pray to god to save us from a deadly virus.
