CORONAVIRUS | About | Symptoms | Prevention and Treatment | History of Origin


The world is in danger and under threat to the Coronavirus. The full name of this deadly Chinese virus is the Novel Corona Virus or the 2019-nCoV. This new version of the Coronavirus infection is detected in the first human body in Wuhan, Hubei Province, China. Corona infection has spread to about five provinces of China since then. Even in Thailand, Singapore, South Korea, Taiwan, Malaysia, several people have been killed by the coronavirus. In China alone, the death toll is already more than 700.

WHAT IS VIRUS?

The virus is a type of microbial substance and not like other germs. They are no cells and behave like an inanimate object. The virus is a compulsory parasite, responsible for many important and infectious diseases in certain organisms, including specific bacteria, plants, and humans. They are incapable of independent reproduction. But when they enter the cell, they become vibrant and self-sufficient. In the end, the host cell is destroyed by the virus.

CORONAVIRUS AND ITS SPECIALTY

Each virus is enclosed by a tight outer layer of protein. This is called a capsid. The capsid wrap consists of nucleic acid - DNA or RNA. In the case of the coronavirus, the capsid contains a homogeneous, positive RNA that binds like a coil. It is also called retrovirus because it contains RNA. The genome of the coronavirus is roughly 20 to 12 kilobases. The word coronavirus comes from a Latin word. The name Corona means 'crown' or 'sunlight'. This is because their appearance on the electron microscope looks the same. China's new species, or Stan's Coronavirus, has been named as "2019-nCoV." This means that the existence of the virus has been reported in 20 years. 'N' or 'Novel' means new or fancy, 'Co' means Corona and 'V' is a virus.

SYMPTOMS

The primary symptoms of coronary heart disease are throat, fever, headache, severe respiratory distress. A lot like pneumonia in fact, the coronavirus kills the infection in the face of known symptoms. Its bite is awful. The infection is not immediately understood. Symptoms take 2 to 3 days to manifest. The way to deal with the virus is still unknown in science. CDC believes at this time that symptoms of 2019-nCoV may appear in as few as 2 days or as long as 14 after exposure. This is based on what has been seen previously as the incubation period of MERS viruses.

HOW DOES CORONAVIRUS SPREAD?

A large corona viridi family made up of the Coronavirus and its many relatives, among animal viruses. Each of them uses the body of an animal as a nurturer to complete the task of breeding for their own needs. The virus only attacks specific host cells. This feature is controlled by genes located in the DNA or RNA of the virus.

The question here is that how does the coronavirus enter a new animal or human body unrelated to a specific organism? Viruses are susceptible to different environmental conditions and this is why they can adapt to changing environmental conditions. This nature of viruses is called mutuality. Scientists believe that this mutation has helped coronary viruses adapt to humans. Gene’s Karsazio is also involved with the incident.

GENETIC MUTATION

The mutation of the coronavirus and its genetic modification are essential for the killer. There is only one purpose. Whether new or old, the virus represses or destroys the host cell's structure. They take on the task of breeding for their own needs. A genetic mutation causes many structural changes in the virus. Scientists believe that this change also changes the direction of the virus. In the case of animal viruses, when the virus invades the host cell, the virus binds to the receptor located in the cell's cell via movement.

PREVENTION FOR 2019 NOVEL CORONAVIRUS

There is currently no vaccine to prevent 2019-nCoV infection. The best way to prevent infection is to avoid being exposed to this virus. However, as a reminder, the CDC always recommends everyday preventive actions to help prevent the spread of respiratory viruses, including:
    1. Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
    2. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
    3. Avoid touching your eyes, nose, and mouth with unwashed hands.
    4. Avoid close contact with people who are sick.
    5. Stay home when you are sick.
    6. Cover your cough or sneeze with a tissue, then throw the tissue in the trash. 
    7. Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.

For information about handwashing, see CDC’s Handwashing websiteFor information specific to healthcare, see CDC’s Hand Hygiene in Healthcare SettingsThese are everyday habits that can help prevent the spread of several viruses. CDC does have specific guidance for travelers.

TREATMENT FOR 2019 NOVEL CORONAVIRUS

There is no specific antiviral treatment recommended for 2019-nCoV infection. People infected with 2019-nCoV should receive supportive care to help relieve symptoms. For severe cases, treatment should include care to support vital organ functions.
People who think they may have been exposed to 2019-nCoV should contact your healthcare provider immediately.

See Interim Guidance for Healthcare Professionals for information on persons under investigation.

CORONER'S HISTORY

About 800 people died worldwide during 2002-2003 by 'Acute Respiratory Syndrome' (SARS) or SARS infection. Coronavirus was also behind this incident. This terrifying new coronary virus in China is a new version of the former Coronavirus. The worldwide threat is spreading by its influence. That is why Coronavirus is called as the brothers of SARS's. It is now called '24-nCoV'. But now doctors have no reason to think that the new virus is as dangerous as the SARS. But such factors as their composition, characteristics, adaptability or means of transmission are not clearly known and here is the fear. Because of the doctors and researchers in the dark about how to prevent the spread of the virus. The prevalence of the disease is higher in West Asian countries, which is called the Middle East Respiratory Syndrome. Humans and carriers of camels were the carriers of the virus.

A report in Wuhan in China warns tourists to stay away from sick people, especially those who have such symptoms. If you travel, stay away from people suffering from pneumonia or colds, runny nose, cough. The coronavirus may spread from the air to cough or cough. But the use of masks to prevent it will not be released. However, with the use of the 'N-1' mask, the virus can be bitten by a viral infection.

Health organizations like the Centers for Disease Control and Prevention (CVC) and the World Health Organization (WHO) has advised that no one should wash their nose, eyes, or mouth with their hands. The hands should be cleaned for at least 20 seconds with soap and water. Stay away from farms and livestock. Thermal cameras have already been installed at international airports for migrants from China to the international airport to prevent the Nova Coronavirus. It helps to identify people affected by the Coronavirus. Heat or heat is emitted from the body of all living things. The thermal sensor inside the thermal camera instantly measures the temperature and displays a thermometer on the display screen. If the temperature is higher than the body's normal temperature, then an infection may result in increased fever or temperature in the body. In this way, the sick person is separated on the basis of body temperature and after treatment, it can be decided whether the person is suffering from coronary disease. However, antibiotics do not work in this disease. There is no specific treatment, no vaccine.
