summer kill coronavirus

Started from China, Coronavirus (COVID-19) now spread worldwide and is affecting over 140 countries and territories around the world and 1 international conveyance (the Diamond Princess cruise ship harbored in Yokohama, Japan). 

No medicine yet developed and no specific drug has been found to use particularly cure this specific disease. Amid, this naturally, spreading and increasing infection, many people including scientist and medical experts admitted that at high temperature regions COVID-19 cannot survive becomes inactive, so let’s find out the truth.

Can Hot Summers Kill Coronavirus?

As per a pathology professor at the University of Hong Kong – Mr. John Nicholls the virus to “burn itself out” with increased temperatures

In a private conference call organized last week by CLSA, a Hong Kong based brokerage firm, investment analysts asked Nicholls, one of the world’s foremost experts on the topic, questions about the novel coronavirus. In the days since the call took place, details of Nicholls’ analysis have surfaced online, including a transcript of the call.

The transcript of the call showed Nicholls believes weather conditions will be a key factor in the demise of the COVID-19. Referencing the SARS outbreak in 2002-03, Nicholls said he thinks similar weather factors will also shut down the spread of the novel coronavirus that spread at fast speed but mortality is less compare to SARS & MERS.

As per Nicholls, three things the virus does not like: 1st Sunlight, 2nd Temperature and 3rd Humidity. And the virus can remain intact at 4 degrees Celsius (39 degrees Fahrenheit) or 10 degrees C (50 F), but at 30 degrees C (86 degrees F) then you get inactivation.” And high humidity — the virus doesn’t like it either,” he added, the transcript of the call showed.

Nicholls thinks confirmed cases will peak. “Sunlight will cut the virus’ ability to grow in half so the half-life will be 2.5 minutes and in the dark it’s about 13 to 20 [minutes],” Nicholls said. “Sunlight is really good at killing viruses.”

Virus is Highly Sensitive to High Temperature

In another study, by a team from Sun Yat-sen University in Guangzhou, the capital of south China’s Guangdong province, sought to determine how the spread of the new coronavirus might be affected by changes in season and temperature.

Published last month, report suggested heat had a significant role to play in how the virus behaves. “Temperature could significantly change Covid-19 transmission,” it said. “And there might be a best temperature for viral transmission.”

The “virus is highly sensitive to high temperature”, which could prevent it from spreading in warmer countries, while the opposite appeared to be true in colder climes, the study said. As a result, it suggested that “countries and regions with a lower temperature adopt the strictest control measures”.

Many national governments and health authorities are banking on the coronavirus losing some of its potency as the weather warms up, as is generally the case with similar viruses that cause the common cold and influenza.

Even, in press conference US president thinks coronavirus will go away in April. Some experts say that could happen – but it’s not purely a good thing.

What WHO Says?

While on the other hand, WHO said “WHO says virus may not vanish in hot summer months as cases rise to 43 in India

As per WHO’s Dr. Mike Ryan, executive director of WHO’s health emergencies programme, says that there is no evidence that the coronavirus will vanish along with the coming of summers. This is an assumption that heat killing coronavirus.

The WHO warns that world leaders must not assume that COVID-19 is a seasonal menace like the flu. Governments across the world must be prepared for further spread of the virus, warns the premier organizations.

WHO officials said they don’t know how COVID-19 behaves. They reiterated the fact that it is not like influenza. This is a unique virus, with unique features. So, don’t live with any kind of myth, instead keep yourself protected and updated.

However, according to the Centre for Disease Control, most viral respiratory diseases are seasonal. In summer months there are less cases or such diseases. But with the coronavirus, no one can be sure.

And, yes, going by the instance of other respiratory diseases, there is certainly scope for hope. But it will be prudent to not base everything on this hope along. Everybody still needs to be prepared for the fact that the coronavirus may not show any signs of subsiding even in the summer months, so be careful and prepared to stay away from this infection.

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

Published

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.

How Exactly Coronavirus Attacks, Infects & Affects Body to Death?

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.

The virus enters the body primarily through the nose. Also, it may get in through eyes and mouth: Image Source

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.”
