1.What is Coronavirus ?

Coronaviruses are a large family of viruses which may cause illness in animals or humans.  In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

2.What is COVID-19 ?

COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.

3.What are the symptoms of COVID-19  ?

The most common symptoms of COVID-19 are fever, tiredness, shortness of breath and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea.  

These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell. Most people (about 80%) recover from the disease without needing special treatment.

Around 1 out of every 6 people who gets COVID-19 becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness. People with fever, cough and difficulty breathing should seek medical attention.

4.What does COVID-19 spread ?

People can catch COVID-19 from others who have the virus. The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales. These droplets land on objects and surfaces around the person.

Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.

WHO is assessing ongoing research on the ways COVID-19 is spread and will continue to share updated findings.    

5. What can I do to protect myself and prevent the spread of disease?

You can reduce your chances of being infected or spreading COVID-19 by taking some simple precautions:
-
Regularly and thoroughly clean your hands with soap for 20 seconds, or an alcohol-based hand rub or sanitizer.

Maintain at least 1.5 metre distance between yourself and anyone who is coughing or sneezing.

Avoid touching eyes, nose and mouth.

 -

Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately.

 -

Stay home if you feel unwell. If you have a fever, cough and difficulty breathing, seek medical attention and call in advance. Follow the directions of your local health authority.

Keep up to date on the latest COVID-19 hotspots (cities or local areas where COVID-19 is spreading widely). If possible, avoid traveling to places  – especially if you are an older person or have diabetes, heart or lung disease.

 

6. Are there any medicines or therapies that can prevent or cure COVID-19?

While some western, traditional or home remedies may provide comfort and alleviate symptoms of COVID-19, there is no evidence that current medicine can prevent or cure the disease. WHO does not recommend self-medication with any medicines, including antibiotics, as a prevention or cure for COVID-19.

However, there are several ongoing clinical trials that include both western and traditional medicines. WHO will continue to provide updated information as soon as clinical findings are available.

 

7.How long does the virus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

8 .Is COVID-19 airborne?

The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or speaks. These droplets are too heavy to hang in the air. They quickly fall on floors or surfaces. 

You can be infected by breathing in the virus if you are within 1 metre of a person who has COVID-19, or by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands.

 

p/s :  New updates about Coronavirus :

1. The 
first case of 2019 Novel Coronavirus  was first detected in Wuhan, China, it was assumed that the coronavirus may have been ongoing in other countries which were misdiagnosed as flu influenza.  Coronavirus  has been renamed COVID-19 by the WHO. The originating of the virus is still a myths.

2. Latest finding a loss of smell or taste may be a sign that you have coronavirus, according to UK researchers.

3. Czech Republic and Slovakia are only countries in Europe to make coronavirus mask-wearing mandatory.

In fact many Asian countries already encourage their citizens to wear masks as health safety in public area as to protect yourself and others.

Especially if you are likely to be in close contact with someone infected, a mask cuts the chance of the disease being passed on. If you’re showing symptoms of coronavirus, or have been diagnosed, wearing a mask can also protect others.

 So masks are crucial for health and social care workers looking after patients and are also recommended for family members who need to care for someone who is ill – ideally both the patient and carer should have a mask.

The reasons some countries are not encouraging to wear masks in the public area  is unless you are sick and also currently there is a shortage supply of marks in world wide during this pandemic period.

4. Currently, there are no vaccines that protect against COVID-19. There is no specific treatment for COVID-19. Early diagnosis and general supportive care and basic protective care measures are important. 

 The most effective ways to protect yourself and others against COVID-19 are to frequently clean your hands, cover your cough with the bend of elbow or tissue and maintain a distance of at least 1 meter (3 feet) from people who are coughing or sneezing.

Take care ......
