In parallel with the fact that people infected with coronavirus with new strains are increasing day by day, the facts about COVID-19 are also controversial hot issue, confusing information. The World Health Organization (WHO) officially changed the situation classification from an emergency public health event of global concern (PHEIC) to a pandemic on March 11, 2020. It is these two words “pandemic” that have scared many people, appearing many false information as well as rumors.

In the following article, Zaloweb.com will synthesize 21 Interesting Facts About The Coronavirus (COVID-19) that are being misunderstood to help readers have a more accurate view of the disease currently raging on every continent of Earth, except Antarctica

21 Interesting Facts About The Coronavirus (COVID-19)

Using chlorine or alcohol spray on the skin can kill the virus in the body

Fact about COVID-19: Alcohol and chlorine are chemicals used to disinfect surfaces and should not be used on the skin. They can not destroy the virus in the body, otherwise potentially harmful if caught in the eyes or mouth.

Only the elderly and the young are at risk of infection

Fact: SARS-CoV-2, like any other virus of the corona family, can infect people of all ages. However, the elderly or individuals who have an underlying medical condition (already with another medical condition) such as diabetes or asthma are more likely to be affected more severely than healthy people.

Children cannot COVID-19 disease

Facts about COVID-19: As mentioned, COVID-19 is irrespective of age group. Most of the SARS-CoV-2 virus positive cases recorded to date have been in adults, but there are still childhood infections. However, the difference is that Covid-19 symptoms in children tend to be less severe.

COVID-19 is like flu, so it can be prevented with the flu vaccine

covid-19-is-like-flu

Fact: The symptoms SARS-CoV-2 causes flu-like symptoms to an infected person at first glance, typically with pain, fever and dry cough. Similarly, both COVID-19 and the flu can be mild, severe, or, in more rare cases, fatal. Both diseases can also lead to pneumonia.

However, the incidence of COVID-19 was more severe with an estimated 5% mortality. Scientists are looking for the exact number, but one fact that we must accept is that the COVID-19 mortality rate is likely to be many times higher than the seasonal flu.

Therefore, COVID-19 cannot be prevented with either the influenza vaccine or the pneumococcal vaccine, the pneumococcal vaccine and the Haemophilus influenza type B (Hib) vaccine. Coronavirus is so new and different that we need a separate vaccine. Researchers are trying to develop the vaccine against SARS-CoV-2 under WHO support.

Getting COVID-19 means death

Fact: As mentioned above, COVID-19 is only fatal in a small number of patients. In a recent report, the China Centers for Disease Control and Prevention concluded that 80.9% of COVID-19 cases were mild. WHO also reports that about 80% of the cases will be of a relatively mild form of disease, without the need for specialized hospital treatment. These mild symptoms include fever, cough, sore throat, fatigue, and chest tightness that has difficulty breathing.

Dogs and cats are the carriers of COVID-19

Fact about COVID-19: Currently, there is very little evidence that SARS-CoV-2 can infect dogs and cats. However, in Hong Kong, a Pomeranian dog with a new strain corona virus positive owner was also infected but did not show any symptoms. Scientists are debating this case as well as the effect it has on the disease.

According to Professor Jonathan Ball – a specialist in molecular virology (University of Nottingham, UK), it is necessary to distinguish between a true infection response and only detecting the presence of virus in the host. The case of the dog still needs further investigation, but the possibility that the virus can infect another dog or human body is not high because of the low virus density. He thinks the possibility of human-to-human transmission is something that needs more special attention at this time.

Masks can protect against viruses

Fact: Health care workers use specialized masks that fit snugly around the face to protect against infection. However, the current disposable masks do not have that capability. They do not quite fit the wearer’s face. Therefore, the patient’s body fluids (coughing, sneezing …) can still enter the mouth and nose of the person wearing the mask.

In addition, tiny virus particles are capable of penetrating directly through the masking material. However, if you have a respiratory illness, wearing a mask can help protect others from getting sick.

In addition, wearing a mask can give you excessive peace of mind, making it easier for the wearer to neglect or ignore other precautions such as hand hygiene. WHO recommends that people taking care of people with suspected COVID-19 infection should wear masks.

In these cases, the mask is only effective if the individual regularly wash his hands with soap and water or use alcohol to disinfect. In addition, proper use of masks and disposal are also important issues to consider.

The hand dryer can kill the new strain corona virus

The temperature from automatic hand dryers commonly found in public toilets does not kill the corona virus that causes COVID-19. The best way to protect yourself and those around you from the virus is to wash your hands with soap and water or use an alcohol-based hand sanitizer.

SARS-CoV-2 is just a mutation of the common cold

high-blood-pressure-symptoms-and-causes

Fact about COVID-19: Corona is a large family of viruses, all with a spiny-like protein on its surface. Certain types of corona viruses that cause pneumonia can enter the human body to turn people into the main host and cause the common cold.

Meanwhile, other strains such as SARS-CoV-2 mainly infect animals. Both Middle Eastern respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) originate in animals and are transmitted to humans. Therefore, SARS-CoV-2 and cold virus are not the same and not related.

It takes at least 10 minutes of close contact with an infected person to become infected with the virus

Fact: The longer a person stays with COVID-19, the higher the risk of getting the virus. However, the possibility of infection persisted for less than 10 minutes of close contact. Protect yourself and those around you by limiting crowds, wearing a mask when you need face-to-face contact, and washing your hands frequently.

Nasal washing with salt water helps to fight the new corona virus

Fact: There is no evidence that saline nasal sprays can protect against respiratory infections. Some studies have shown that this approach can reduce symptoms of acute upper respiratory tract infection, but scientists have not yet recognized the use of salt water as a preventive measure of infection.

Rinsing your mouth with salt water is also a way to kill the virus

The truth about COVID-19: Doctors say salt water when rinsing will create a hypertonic environment, microorganisms will not have a chance to grow and be destroyed. However, salt water rinsing is only a partial support, not a complete treatment of the epidemic. And the salt water can only disinfect in the mucosa and in the cells is not affected much. Meanwhile, the virus that causes COVID-19 is proliferating in the body’s cells.

Use antibiotic treatment

Fact: Antibiotics only kill bacteria, not viruses. The indiscriminate use of antibiotics can cause many unpredictable harms, so patients are not allowed to take antibiotics without a prescription from their doctor.

The body temperature scanner can diagnose COVID-19

Fact: A fever scanner can detect fever symptoms. However, it is important to note that some other medical conditions, such as the flu, also cause fever.

In addition, symptoms of COVID-19 may not appear immediately but may take 2-10 days after infection. This means that a person carrying the SARS-CoV-2 virus completely has a normal body temperature for a few days before the fever starts.

Eat lots of garlic

Fact about COVID-19: In fact, there are studies showing that eating garlic slows down the growth of some bacteria. However, COVID-19 is caused by a virus and there is no evidence that garlic can protect humans against COVID-19.

Goods sent from China could spread the virus

From previous research on viruses belonging to the same corona family, including those that cause SARS and MERS, scientists believe that the virus cannot survive on letters or parcels during the period. long time.

However, according to the most recent report by the US Centers for Disease Control and Prevention, the new coronavirus can remain on the surface of objects for 17 days, but there is no evidence that humans can be infected from these objects. The above findings further emphasize the need for daily hand and body hygiene, especially those in contact with object surfaces outside the environment.

People with COVID-19 can treat themselves at home

what-are-the-early-signs-of-detection-of-the-coronavirus

There is no cure for COVID-19 at home, including taking vitamin C supplements, using essential oils, silver colloid, sesame oil, garlic, detergent or drinking water every 15. minutes to keep the throat moist. A simpler and better prevention method is still to wash your hands properly, away from crowded places.

The corona virus can be transmitted through urine and feces

According to Professor John Edmunds (London School of Hygiene & Tropical Medicine in the US), every time we swallow, secretions like saliva from the upper respiratory tract also enter the intestines, including viruses and bacteria. Here, they are denatured under the acid condition from gastric juice. With sophisticated and modern detection mechanisms, it is possible to detect these viruses in human feces.

Usually, fecal viruses do not infect others because they have been killed. However, it is worth noting that some studies have concluded that the SARS-CoV-2 virus may still be present in the feces.

Viruses will die when the temperature increases

Some viruses like cold and flu viruses spread more easily during the cold months, but that doesn’t mean they are completely inactive when the temperature heats up.

Likewise, do not use UV lamps to disinfect hands or other skin areas as UV radiation can cause skin irritation. Currently, scientists still do not know how changes in temperature in the environment will affect the activity of SARS-CoV-2.

Corona virus is the most dangerous virus to humans

Although SARS-CoV-2 is exhibiting greater severity than the flu virus, it is not the most dangerous virus that humans have ever faced. In 2014-2016, Africa experienced an Ebola epidemic with a high mortality rate, averaging about 50%.

The new corona virus originated from a laboratory in China

Although there are many rumors out there about this information, there is no concrete evidence. In fact, a recent study has shown that this virus is a natural product of evolution. Some researchers believe that SARS-CoV-2 may have been transmitted from pangolins to humans. Others believe the virus may have originated from bats – which has been the case in the past with SARS.

The disease caused by coronavirus is spread mainly through contact with an infected person when coughing or sneezing or when a person touches a surface or object that has the virus on it, and then touches their eyes, nose or mouth with their hands. The current necessity of each individual is to limit leaving the territory, avoid crowds, use masks and practice hand hygiene regularly.
