CoronaVirus: Wuhan-CoV or COVID-19
Wuhan-CoV or 2019 nCoV
Ways to prevent the coronavirus
What is a coronavirus?
A coronavirus is a kind of common virus that causes an infection in your nose, sinuses, or upper throat. Most coronaviruses are not dangerous.
“Coronaviruses were first identified in the 1960s, but we don’t know where they come from. They get their name from their crown-like shape. Sometimes, but not often, a coronavirus can infect both animals and humans. Most coronaviruses spread the same way other cold-causing viruses do: through infected people coughing and sneezing, by touching an infected person’s hands or face, or by touching things such as doorknobs that infected people have touched. Almost everyone gets a coronavirus infection at least once in their life, most likely as a young child. In the United States, coronaviruses are more common in the fall and winter, but anyone can come down with a coronavirus infection at any time.” (Ref: https://www.webmd.com/lung/coronavirus#1)
The Centers for Disease Control and Prevention (CDC) is closely monitoring an outbreak of respiratory illness caused by a novel (new) coronavirus first identified in Wuhan, Hubei Province, China. Chinese authorities identified the new coronavirus, which has resulted in thousands of confirmed cases in China, including cases outside Wuhan City. Additional cases have been identified in a growing number of other international locations, including the United States. There is much more to learn about the transmissibility, severity, and other features associated with 2019-nCoV and investigations are ongoing.
How 2019-nCoV Spreads
Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with MERS and SARS.
When person-to-person spread has occurred with MERS and SARS, it is thought to have happened mainly via respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory pathogens spread. Spread of SARS and MERS between people has generally occurred between close contacts.
It’s important to note that how easily a virus spreads person-to-person can vary. Some viruses are highly contagious (like measles), while other viruses are less so. It’s important to know this in order to better understand the risk associated with this virus. While CDC considers this is a very serious public health threat, based on current information, the immediate health risk from 2019-nCoV to the general American public is considered low at this time.
Here are some effective ways to prevent the coronavirus as recommended by health practitioners.
About the virus:
- It is pretty large in size (cell is about 400-500 nm diameter), so any normal mask (not just the N95 feature) should be able to filter it out. However, when someone who’s infected sneezes in front of you, it will take a great 3 meters (about 10 feet) before it drops to the ground and is no longer airborne.
- When the virus drops on metal surface, it will live for at least 12 hours. So remember if you come in contact with any metal surface, wash your hands with soap thoroughly.
- The virus can remain active on fabric for 6-12 hours. Normal laundry detergent should kill the virus. But if you are really worried, you can add some non-chlorine bleach or oxygen bleach . For winter clothing that does not require daily washing, you can put it out under the sun to kill the virus.
Symptoms of pneumonia caused by corona virus:
- It will first infect the throat, so the throat will have the dry sore throat feeling which will last for 3 to 4 days
- Then the virus will blend into the nasal fluid and drips into the trachea and enter the lungs, causing pneumonia. This process will take 5 to 6 days.
- With pneumonia, comes high fever and difficulty in breathing. The nasal congestion is not like the normal kind. You will feel like you are drowning in water. It’s important to go seek immediate medical attention if you feel like this.
How to protect yourself:
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, CDC always recommends everyday preventive actions to help prevent the spread of respiratory viruses, including:
- The most common way of getting infected is by touching things in public, so you must wash your hands frequently. The virus can only live on your hands for 5-10 mins, but a lot can happen in those 5-10 mins (you can rub your eyes or pick your nose unwittingly).
- Wash your hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.
- Aside from washing your hands frequently, you can gargle with Betadine Sore Throat Gargle to eliminate or minimize the germs while they are still in your throat (before dripping down to your lungs).
- Avoid touching your eyes, nose, and mouth with unwashed hands.
- Avoid close contact with people who are sick
- Stay home when you are sick
- Cover your cough or sneeze with a tissue, then throw the tissue in the trash can
- Clean and disinfect frequently touched objects and surface.
Statement from Dr. Yuen Kwok Yung, a doctor during the previous SARS period gave the following advice in a speech yesterday.
- If going on a flight, make sure you wear your mask properly.
- Always have antiseptic cleanser or towel readily available.
- The virus “ coronavirus” is similar type of virus like the previous SARS or MERS. This time it is OC43. There is still no known method of tackling this virus.
- If you have to go to the market, grocery or any crowded places, make sure you wear a mask. Be very vigilant.
- Health Authority announced that this virus is very serious. However, as the virus is found to be able to enter your body if your throat or throat mucous is dry, the one precaution they suggest which can be taken is to ensure your throat or throat mucous is always in a moist condition. In fact, they suggest not to allow your throat to become dry, as in 10 minutes of being dry, the virus will find ways to enter into your body. So do not refrain from drinking water, always have a bottle handy.
For adults, they suggest drinking 50-80 cc of warm water; for children 30-50 cc. Just drink if you feel your throat is dry. Do not hesitate. However drinking more than the amount recommended is not necessary, as it will just want to pass through your system. The idea is to “Keep your throat constantly moist.”
- Before end of March, try not to enter crowded places, MTR (in our case MRT and LRT) or any public transport, and wear a mask if necessary.
- Avoid eating too much deep fried food and take plenty of Vitamin C.
- Control Center advice on symptoms of this virus:
– fast and high fever, hard to lower, but if successful, the fever will return very soon.
– next stage is coughing, in long duration, people affected are mainly children.
– Adults has mainly throat symptoms, together with headaches and physical discomforts.
– the virus is “highly” contagious.
– elderly and young children are most susceptible, so take super precaution.
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 seek medical care right away.
Hope this helps!
