coronavirus affect infect body

As the COVID-19 pandemic spreads across the world – canceling major events, closing schools, upending the stock market and disrupting travel and normal life – People taking precautions against the new coronavirus that causes the disease sickening and killing thousands worldwide compelling people stay at home and avoid public contacts.  

The WHO and U.S. Centers for Disease Control and Prevention advise the public to be watchful for fever, dry cough and shortness of breath, symptoms that follow contraction of the new coronavirus known as SARS-CoV-2 or COVID-19.

From infection, it takes approximately five to 12 days for symptoms to appear. So, right here we brought how exactly coronavirus attacks, infects and affect your body and what happens inside the body when it takes hold and causes death.

How Coronavirus Spread To Humans?

The virus can spread person-to-person within 6 feet through respiratory droplets produced when an infected person coughs or sneezes and remains on a surface or object, be transferred by touch and enter the body through the mouth, nose or eyes.

How Coronavirus Attacks and Enters Your Body?

As per, Dr. Martin S. Hirsch, a senior physician in the Infectious Diseases Services at Massachusetts General Hospital, he said there’s still a lot to learn but experts suspect the virus may act similarly to SARS-CoV from 13 years ago.

“It’s a respiratory virus and thus it enters through the respiratory tract, we think primarily through the nose,” he said. “But it might be able to get in through the eyes and mouth because that’s how other respiratory viruses behave.”

What happens when Coronavirus Enters Your Body?

Once inside the body, it begins infecting epithelial cells in the lining of the lung. A protein on the receptors of the virus can attach to a host cell’s receptors and penetrate the cell. Inside the host cell, the virus begins to replicate until it kills the cell.

This first takes place in the upper respiratory tract, which includes the nose, mouth, larynx and bronchi. The patient begins to experience a mild version of symptoms: dry cough, shortness of breath, fever and headache and muscle pain and tiredness, comparable to the flu.

Symptoms often start in the back of the throat, with a dry cough: Image Source

Dr. Pragya Dhaubhadel and Dr. Amit Munshi Sharma, infectious disease specialists at Geisinger, say some patients have reported gastrointestinal symptoms such as nausea and diarrhea, however it’s relatively uncommon. And symptoms become more severe once the infection starts making its way to the lower respiratory tract.

How Exactly Coronavirus Affect Our Body?

It can take two to 14 days for a person to develop symptoms after initial exposure to the virus, Hirsch said. The average is about five days.

The WHO reported last month about 80% of patients have a mild to moderate disease from infection. A case of “mild” COVID-19 includes a fever and cough more severe than the seasonal flu but does not require hospitalization.

Those milder cases are because the body’s immune response is able to contain the virus in the upper respiratory tract. And younger patients have a more vigorous immune response compared to older patients.

The 13.8% of severe cases and 6.1% critical cases are due to the virus trekking down the windpipe and entering the lower respiratory tract, where it seems to prefer growing and target the lungs.

In more severe cases, the virus goes down the windpipe and into the lower respiratory tract: Image Source

According to Dr. Raphael Viscidi, infectious disease specialist at Johns Hopkins Medicine – the virus continues to replicate and journeys further down the windpipe and into the lung, it can cause more respiratory problems like bronchitis and pneumonia.

Pneumonia and Autoimmune Disease

As per the doctors, Pneumonia is characterized by shortness of breath combined with a cough and affects tiny air sacs in the lungs, called alveoli, which is the point where oxygen and carbon dioxide are exchanged in our body.

When pneumonia occurs, the thin layer of alveolar cells is damaged by the virus. The body reacts by sending immune cells to the lung to fight it off.

And that results in the linings becoming thicker than normal, as they thicken more and more, they essentially choke off the little air pocket, which is what you need to get the oxygen to your blood.

Airways starts swelling and decrease airflow due to filled with fluids: Image Source

Actually, it is basically a war between the host response and the virus depending on who wins this war we have either good outcomes where patients recover or bad outcomes where they don’t and become critical resulting in death.

How Coronavirus Causes Organ Failure?

Further becoming stronger, coronavirus restricting oxygen to the bloodstream deprives other major organs of oxygen including the liver, kidney, and brain. A small number of severe cases that can develop into acute respiratory distress syndrome (ARDS), which require a patient to be placed on a ventilator to supply oxygen.

Lastly Coronavirus causes severe lung damage and multiple organs failures: Image Source

However, if too much of the lung is damaged and not enough oxygen is supplied to the rest of the body, respiratory failure could lead to organ failure and death of the patients.

As per the Viscidi, the outcome is uncommon for the majority of patients infected with the coronavirus. As those most at risk to severe developments are older than 70 and have weak immune responses.

While other than old age individuals, people at risk include pulmonary abnormalities, chronic disease or compromised immune systems, such as cancer patients who have gone through chemotherapy treatment.

Viscidi urges the public to think of the coronavirus like the flu because it goes through the same process within the body. Many people contract the flu and recover with no complications. “People should remember that they’re as healthy as they feel,” he said. “And shouldn’t go around feeling as unhealthy as they fear due to unavailability of medicines.”

Things You Dot Know About Coronavirus

Coronavirus or COVID-19, became one of the worst pandemics of the century, infected millions and killed tens of thousands of people globally. The virus is deadly, as there is no vaccine developed yet and it is a very highly contagious disease.

Declared as a pandemic and people know lots of things about this deadly virus, like its symptoms, how it spread, what are precautions you need to take to keep yourself protected, and what are the possible remedies and treatments, etc.

But since this virus has been found, it has mutated itself and now there are different symptoms and new things are caming out by various research and studies. So, you need to read what you don’t know about COVID-19 and be aware of this deadly virus.    

Five Things You Still Don’t Know About COVID-19

Things You Still Don’t Know About COVID-19

#1 Men are Dying More Compared to Women

As per the report published in Aljazeera, men are dying more compared to their women. In China, 2.8 percent of men who caught the virus had died, compared with 1.7 percent of women who contracted it. While in Italy, where the death rate is currently 7.2 percent for men and 4.1 percent for women.

Men Dying more compared to Women

Likewise, South Korea, where extensive testing was carried out, despite showing that the proportion of women who tested positive for the virus was higher than that of men, about 54 percent of the reported deaths were still among men.

Similarly, in other countries, men are more getting infected and also dying higher compared to their female counterparts. And as per the doctors and medical experts, the main reason behind this is, unhealthy lifestyle, excessive smoking or drinking habits, week immune system, hormonal differences and extra X chromosome in women compare to men.  

#2 Many Patients are Losing their Sense of Smell

As per the research and new studies, patients suffering from coronavirus infection are losing their sense of smell. Though, as per the British Rhinological Society, post-viral anosmia is one of the leading causes of smell loss in adults, accounting for up to 40% of cases.

And in a few countries, at least 61 percent reported reduced or lost sense of smell, that the mean onset for reduction or loss in the sense of smell was 3.4 days. And in many countries cases, 73% patients lost their sense of smell prior to coronavirus diagnosis.   

#3 Smokers, Diabetics, Hypertensives Can Suffer Strokes

As per the new studies and research on COVID-19, people suffering from coronavirus infection and having chronic diabetes, hypertension, smoking or bad health conditions can also suffer from unusual strokes or even heart attacks with deadly consequences. 

Strokes due to coronavirus

Covid-19 infection presenting with cerebrovascular accident (stroke) up to 5 to 6 percent, from different studies. And, as per the studies in US, certain young persons have also presented for the first time with stroke due to COVID-19.

#4 COVID-19 in Semen and Can be Sexually Transmitted

Coronavirus is reaching everywhere. As per the recent studies in China, Coronavirus was found in the semen of recovering and acute male COVID-19 patients. Though it remains unknown, according to the CDC, whether the disease can be transmitted sexually. 

coronavirus in semen fact check

In the study, originally published on JAMA Network Open and conducted in Shangqiu, China, six patients—15.8%—of 38 COVID-19-positive males had the virus in their semen. And four of those men with COVID-19 in their semen were at the acute stage of infection, while the other two had already recovered.

Though, the research neither confirms nor denies whether the virus can be sexually transmitted or not. As researchers did not follow up with the participants to determine the duration of coronavirus in their semen and whether the men had spread it to their sexual partners or due to any other sources of transmission. 

#5 There are 10 Different Types of Coronavirus

Seems very amazing to listen, but you are reading correctly. Yes, coronavirus has mutated itself into different forms and now 10 different types of COVID-19 virus are infecting people globally also making it difficult for medical science to research and develop the right vaccine or medicine for the treatments for every virus.

different types of coronavirus

As per the research from the 3,600 coronaviruses sample collected from 55 countries from December 2019 to April 6, 2020, for their study coronavirus had evolved into multiple types during its initial spread in China and the rest of the world.      

Currently, there are 11 types of coronaviruses that are classified into O, A2, A2a, A3, B, B1, O, and so on, including type O which is the ‘ancestral type’ that was first originated from its epicenter in the city of Wuhan, China.

Why Young People are also Dying Because of Coronavirus: 4 Reasons

Published

on

young people dying coronavirus

Coronavirus or COVID-19 has infected all the age groups of people globally, and its true old age people are mainly and easily getting infected and die due to this infection. But do you know many young people are also dying because of this disease?

And recently researchers have identified reasons why young who are fit and healthy could be dying of the new coronavirus COVID-19. Though, mostly aged people are dying, but it also a true, number of younger people – with no known health problems – have died in the UK or other nations after testing positive for the disease.

Dr. Sanjay Gupta, a neurosurgeon and chief medical correspondent for CNN, wrote in his article, all about the reasons behind the death of young people due to coronavirus. So let’s find out what Dr. Gupta wrote and find out the reasons.  

4 Reasons Young People Dying Due to COVID-19

#1 Variations in the Genetic Factors  

Dr. Gupta said, “One possibility is a gene variation in the ACE2 gene. ACE2 is an enzyme that attaches to the outer surface of cells in the lungs, as well as the heart.” Coronavirus uses such enzymes to enter airway cells and finally into the lungs.

Scientists studying are analyzing the DNA of patients who had serious cases of COVID-19 and no underlying health issues such as diabetes or heart or lung disease, and comparing it with the DNA of those with mild or no pre-existing disease at all.

#2 Depletion of Vital Fluid in the Lungs

As per Dr. Gupta – Another possible factor is that pulmonary surfactant – a fluid secreted by the cells of the tiny air sacs in the lungs – becomes depleted in COVID-19 patients.

This fluid helps the lungs to expand and contract normally, but when the supply is depleted that function is disrupted, the air sacs can collapse and it becomes much harder to breathe for the patients who then supported with ventilators.

Moreover, Dr. Gupta also wrote, if you think of your lungs as a sponge, surfactant would be the detergent which would make them soft and pliable. Without surfactant, however, your lung becomes stiff and hard to squeeze making difficult for patents to struggle to breathe even when they are put on the ventilator.  

#3 Highly Sensitive Immune System

In the study, researchers are also looking into the human immune system and how it responds to viruses and bacteria. As it is very much possible that a healthy immune system could lead to severe problems among young people.

The third reason Dr. Gupta wrote: “In some young, healthy people, a very reactive immune system could lead to a massive inflammatory storm that could overwhelm the lungs and other organs. In those cases, it is not an aged or weakened immune system that is the problem – it is one that works too well.”

#4 Negligence in Taking the Precautions

The fourth and last reason, there is a possibility some young people thinking they are healthy and invincible, and therefore taking fewer precautions or ignoring social distancing rules to prevent themselves from catching coronavirus.

Those people “have been exposed to much larger viral loads from the environment or suffering from flu, Dr. Gupta added. In the UK, the most seriously affected patients have been the elderly and vulnerable, according to Government statistics.

In its most recent update, on March 31, the Office for National Statistics wrote: “The vast majority of deaths involving COVID-19 have been among people aged 65 years and over (100 out of 108), with almost half (45) of these occurring in the over-85 age group.”

In US 29% Patients are 20–44 years

In the US, as of March 16, a total of 4,226 COVID-19 cases had been reported, with reports increasing to 500 or more cases per day beginning March 14.

 Number of new COVID-19 cases reported in US in February 12–March 16, 2020: Image Source

Among 2,449 patients with known age, 6% were aged ≥85, 25% were aged 65–84 years, 18% each were aged 55–64 years and 45–54 years, and 29% were aged 20–44 years. Only 5% of cases occurred in persons aged 0–19 years.
