COVID-19 ; Brief summary of corona virus

INTRODUCTION

Corona viruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans, these viruses cause respiratory infections that can range from mild to fatal. Mild illnesses include some cases of colds (which are also caused by other viruses, often nasal viruses), while more deadly species can cause SARS, MERS, and COVID-19. Symptoms differ in other types: in chickens, they cause upper respiratory diseases, while in cows and pigs they cause diarrhea. There are as yet no vaccines or antiviral drugs to prevent or treat corona virus infection.

Coronary viruses vary greatly in risk factor. Some people can kill more than 30% of people infected, such as the SK virus that causes respiratory syndrome in the Middle East, and some are relatively harmless, such as the common cold. Corona viruses can cause a common cold with major symptoms, such as fever and sore throat from bloated nasal polyps. Corona viruses can cause pneumonia (either direct viral pneumonia or secondary bacterial pneumonia) and bronchitis (either direct viral bronchitis or secondary bacterial bronchitis).

The human corona virus discovered in 2003, SARS-CoV, which causes severe acute respiratory syndrome (SARS), has unique pathology because it causes upper and lower respiratory infections.

Six types of human corona viruses are known, with one type splitting into two different strains, which makes seven strains of human corona virus completely.

Four human corona viruses produce symptoms that are generally mild:

1. Human corona virus OC43 (HCoV-OC43), β-CoV
2. Human corona virus HKU1 (HCoV-HKU1), β-CoV
3. Human corona virus 229E (HCoV-229E), α-CoV
4. Human corona virus NL63 (HCoV-NL63), α-CoV

Three human corona viruses produce symptoms that are potentially severe:

1. Middle East respiratory syndrome-related corona virus (MERS-CoV), β-CoV
2. Severe acute respiratory syndrome corona virus (SARS-CoV), β-CoV
3. Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), β-Co

COVID-19 CURRENT SCENARIO

SPREAD OF CORONA VIRUS

People can catch COVID-19 from others infected with the virus. The disease is spread primarily from person to person through small drops from the nose or mouth, which are expelled when coughing, sneezing or speaking. These drops are relatively heavy, do not travel far and quickly sink to the ground. People can catch COVID-19 if they inhale these drops from someone who has the virus. This is why it is important to stay away from at least 1 meter (away from others). These drops can land on objects and surfaces around a person such as tables, door handles and handrails. People can become infected by touching these objects or surfaces, then touching their eyes, nose, or mouth. That is why it is important to regularly wash your hands with soap and water or rub it with alcohol.

Symptoms

The most common symptoms are:

• Fever
• dry cough
• Tired

Less common symptoms:

• Aches and pains
• Sore throat
• Diarrhea
• conjunctivitis
• Headache
• Loss of taste or smell
• Skin rash, or the color of the fingers or toes changed

Serious symptoms:

• Difficulty breathing or shortness of breath
• Chest pain or pressure
• Speech or movement loss

Precautionary steps

• wash your hands 
• use hand sanitizers
• use face mask
• social distancing and social isolation
• don't touch your face area
• stay at home

Essential fruits and vegetables used as immunity booster

More research into the phyto-chemicals present in licorice root may result in treatment for the new strains of Corona virus in China liqurice root and corona virus

Licorice root has been used for ages in ancient Egyptian medicine as well as in Indian Ayurvedic medicine as well as in traditional Chinese medicine. Licorice root was already known for its antiviral properties, but researchers note that during the SARS outbreak, certain groups of people drinking the mixing of traditional Chinese medicine that they contained during the SARS outbreak had not contracted the virus despite being exposed to it by having infected relatives in the same family. This was what drove the initial research. "
