Coronavirus

What is Coronavirus?

Coronavirus is a new strain of virus that has never appeared in humans, whose name comes from Latin origin. Coronavirus is a virus that is surrounded by spikes on the outside, interacting with receptors on cells, following a mechanism similar to keys and locks, thereby allowing the virus to enter inside.

When was Coronavirus discovered?

The outbreak in late December 2019, originating in a seafood market in Hunan, Wuhan, Central China, the Coronavirus was initially confirmed as a type of "strange pneumonia" or "unknown pneumonia" reason". The acute respiratory infection produced by Coronavirus swiftly damaged the economic and social spheres, the financial market wobbled, and the world economy went into a recession with a high rate of inflation after just 100 days of emergence. Unemployment and poverty rates are unprecedented in history.

The name Coronavirus is derived from Latin, where “corona” means “crown”. This virus has spikes on the outside, which interact with receptors on cells, in a similar way to keys and locks, thereby allowing the virus to enter inside.

Coronavirus in the world

According to the statistics of worldometers.info, the total number of new coronavirus infections (SARS-CoV-2) causing acute respiratory infections (COVID-19) globally is 190,197,767 cases, including 4,089,588 people died.

The disease has so far appeared and spread in 219 countries and territories. Countries also recorded 173,387,681 recovered patients, 12,720,498 active cases and 79,348 cases currently in critical condition.

The COVID-19 epidemic is complicated in many countries, such as Indonesia, Russia, and Brazil, and has spread widely, with a high number of cases in many countries. Worrying waves of the disease have re-emerged in some regions of the world after a series of countries faced new outbreaks and discovered new strains of the SARS-CoV-2 virus. . Many countries have accelerated vaccine programs.

The country most seriously affected is still the US with 624,238 deaths out of a total of 34,919,774 infections. In the context of the number of new cases showing signs of increasing again, many major cities in this country, including Los Angeles, have tightened epidemic prevention regulations...

South Korea is also entering a second COVID-19 pandemic summer when the number of new daily infections has been at a high level throughout the past week. In 24 hours, the country recorded 1,536 new COVID-19 infections, including 1,476 community infections. This is the 10th day in a row that the number of new daily infections in South Korea has exceeded 1,000, and nearly 70% of them are in the Seoul metropolitan area and surrounding areas.

In Europe, the European Center for Disease Prevention and Control (ECDC) forecasts a sharp increase in the number of new COVID-19 cases, due to the spread of the Delta variant while many European countries relax measures. . In its weekly report, ECDC forecasts that the number of new COVID-19 cases in EU member states, Norway and Iceland this week will be at 420 cases per 100,000 people, an increase of nearly 5 times compared to the previous week.

 The ECDC report states that the worsening disease situation in many countries is expected to continue due to the strong spread of the Delta variant. Not only that, but a large-scale COVID-19 immunization program may result in an increase in the number of hospitalizations and fatalities from COVID-19, albeit at a slower rate.

What is the new strain of coronavirus?

Coronavirus 2019 is a virus that causes an infection in the nose, sinuses, or throat. There are 7 types of Coronavirus, of which 4 are not dangerous: 229E, NL63, OC43, and HKU1; The other two types, MERS-CoV and SARS-CoV, are more dangerous and have caused global pandemics. In addition, there is a new strain of Coronavirus with the symbol 2019-nCoV or nCoV, also known as the "Wuhan Virus" that has been going on since the end of 2019 until now. This is the causative agent of acute pneumonia, causing more than 100 million cases, more than 2 million deaths worldwide.

Because this is a new virus, people have never developed immunity, including cross-immunity. Coronaviruses are a large family of viruses that usually infect animals, but they can sometimes evolve and infect humans. When the virus enters the body, it enters some cells and takes over the cellular machinery (causing specific inflammatory damage in the respiratory tract), and the virus redirects that machinery to serve itself. , creating new viruses and infecting others. People infected with 2019-nCoV have acute symptoms: cough, fever, shortness of breath, which can progress to severe pneumonia, progressive acute respiratory failure, and death; especially in the elderly, people with chronic diseases, immunocompromised.

The incubation period of 2019-nCoV is 14 days, which is 14 days from the time of infection with Coronavirus to the time of illness. This makes current control measures very difficult to detect.

How does Coronavirus cause disease?

Most coronaviruses have the same route of transmission as other cold viruses, which are:

Infected people cough and sneeze without covering their mouths, leading to the release of droplets into the air, spreading the virus to healthy people.

A healthy person touches or shakes hands with someone who has the Coronavirus, causing the virus to pass from person to person.

A healthy person comes into contact with a surface or object that has the virus on it and then touches his or her nose, eyes, or mouth.

Symptoms of a Coronavirus include fever or chills, cough, shortness of breath, or trouble breathing. Fatigue, aches, and pains in the muscles, Headache, New olfactory or olfactory loss, Stuffy or runny nose, sore throat

How does the virus spread?

Much remains unclear about how the new strain of virus COVID-19 spreads. The current information and knowledge are largely based on known information of similar strains of Coronavirus. Coronaviruses are a wide family of viruses found in a variety of species, including camels, cattle, cats, and bats. Animal coronaviruses such as MERS and SARS rarely infect humans and are less contagious between people.

Typically, person-to-person spread occurs through close contact person-to-person spread is thought to take place largely through droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory pathogens are spread. These droplets can land in the mouths or nostrils of surrounding persons, or they might be inhaled and enter the lungs.

How to prevent Coronavirus?

It is important to note that precautions are taken to reduce the risk of infection. While it has not been proven to protect against coronavirus, wearing a mask is essential to help prevent individuals from infecting others.

It is more important to make sure that we always keep our hands clean. Throughout the day, we touch a variety of items, including our faces and even family members. This is the method through which viruses and bacteria propagate. Other basic steps you may take to assist prevent the spread of respiratory infections are listed below.

• In the absence of soap and water, use an alcohol-based hand sanitizer containing at least 60% alcohol. If your hands are dirty or stained, always wash them with soap and water.
• Hands that have not been washed should not be used to touch your eyes, nose, or mouth.
• Avoid coming into contact with ill people.
• When you're unwell, stay at home.

• Disinfect frequently touched objects and surfaces
