The Covid-19 coronavirus outbreak is a new illness and scientists are still assessing how it spreads from person to person, but similar viruses tend to spread via cough and sneeze droplets.
When an infected person coughs or sneezes, they release droplets of saliva or mucus. These droplets can fall on people in the vicinity and can be either directly inhaled or picked up on the hands then transferred when someone touches their face, causing infection. For flu, some hospital guidelines define exposure as being within six feet of an infected person who sneezes or coughs for 10 minutes or longer.

Stay six feet from infected individuals.
Viruses can also be spread through droplets landing on surfaces such as seats on buses or trains or desks in school. However, whether this is a main transmission route depends on how long viruses survive on surfaces – this can vary from hours to months.
There is anecdotal evidence that the virus can be spread by people before they have symptoms. Some other illnesses such as flu can be passed from one person to another before symptoms occur – but the extent to which this is happening with the new coronavirus is not well understood yet.
How to protect yourself and others
FacebookTwitterPinterest
Wash your hands.
Wash your hands: wet your hands with clean, running water and apply soap. Lather your hands, including the backs, between your fingers, and under your nails and scrub for at least 20 seconds. Rinse.

Cover your mouth.
Cover your mouth and nose with a tissue when you cough or sneeze, then throw the tissue in the bin and wash your hands. If you do not have a tissue to hand, cough or sneeze into your elbow rather than your hands.

Face masks offer some protection.
Face masks offer some protection as they block liquid droplets. However, they do not block smaller aerosol parles that can pass through the material of the mask. The masks also leave the eyes exposed and there is evidence that some viruses can infect a person through the eyes.

Seek medical help.
Seek early medical help if you have a fever, cough and difficulty breathing, and share your travel history with healthcare providers.
FacebookTwitterPinterest
Avoid live animals.
If visiting live markets in affected areas avoid direct, unprotected contact with live animals and surfaces that have been in contact with animals.
FacebookTwitterPinterest
Avoid raw foods.
If you have returned from an affected area in the last two weeks, stay indoors and avoid contact with other people for 14 days. This means not going to work, school or public areas.

Hobby
My hobby I like most is listening to music. I started listening many kind of music when I was a little girl.
I like many kind of music, especially I am interested in the US - UK songs. I studied English to understand the meaning of the songs I have heard. At first, I listened country music. They were quite slowly and it was quite easy to hear and understand them. Now, I can understand most of all the US - UK songs I have heard. That's so great!
I have usually spent my free time to listen the best songs. I like listening to music because my soul is relaxed when I listen.
Music would be my lifelong friend. I would never stop listening to music.

It is English subject that I like best in school. I like English because it helps me open the big world. First of all, I can talk with people who are in the English-speaking world. Secondly, I can find many documents written by English for studuing. Thirdly, I can watch movie and news without subtitle. Last but not least, it makes me interesting when studying. To study it well, I sometimes take a note and past it in somewhere in my room. I always do all exercises before going to school. And I am very enthusiastic in the class. English is known to be very dificult and many students hate studying it. It my feeling that the problem is the methods teaching of Vietnam is not suitable. Student must study grammar hardly. I hope it will change in the future. In short, English is very necessary for modern life, I hope all students find in interesting.

well, I am a very foody person and there are a lot of food I . It is quite difficult to think of one. I would to talk about a popular menu in my country which is one of my favourite food also. It is steamed/plain rice and shahi paneer. I belong to Punjabi family so that I love spicy and shahi foods.
I will talk about how I cook my shahi paneer at home. A small amount of oil is placed in a heated pan. Then, I put some finely chopped garlic until it turns golden brown. Add onions.when it turns golden brown then I blend it with help of a blender. a mixture of this I put some chopped tomatoes and heat it again.after that I add some cashews and fresh cream which provide creamy and rich gravy of our shahi paneer.apart from that then add paneer cubes, all spices and cook it till 20 minutes. Then it is done and ready to be served. You may also add some curd in place of fresh cream.
I it because it is easy to prepare and it is very delicious. gravy of this also feel me rich and when I taste it just melted our mouth.
This recipe is common in my country and I eat it about a twice week. I it because it does not require much effort to prepare and it is also not expensive.
Do you feel okay? Good luck to you.
Hope you get good grades.

Cause:
The Viruses:
One reason why there is no cure for the common cold is that more than 200 different viruses can cause cold symptoms.
Some, such as rhinoviruses, seldom produce serious illnesses.
Others, such as respiratory syncytial virus (RSV), produce mild infections in adults but can lead to severe lower respiratory tract infections in young children.
ADVERTISEMENTS:
Rhinoviruses (from the Greek rhin, meaning “nose”) cause an estimated 30 to 50 percent of all colds. Scientists have identified more than 100 distinct rhinovirus types. Rhinoviruses grow best at temperatures of about 9IT, (the temperature inside the human nose). Scientists think coronaviruses cause about 10 to 15 percent of all adult colds. They bring on colds primarily in the winter and early spring. Although many coronaviruses infect animals, only five infect humans, causing respiratory tract illness.
Adult cold symptoms also are caused by viruses that are responsible for other, more severe illnesses. These viruses are: adenoviruses, coxsackieviruses, echoviruses. orthomyxoviruses (including influenza A and B viruses, which cause flu), paramyxoviruses (including several parainfluenza viruses), RSV, and enteroviruses. Researchers still haven’t identified the causes of 20 to 30 percent of adult colds, presumed to be viral.
The cold season:
Seasonal changes in relative humidity also may affect the occurrence of colds. The most common cold-causing viruses survive better when humidity is low Cold weather also may make the inside lining of your nose drier and more vulnerable to viral infection.
Other factors:
Although a connection exists between the number of cases of the common cold and the fall and winter seasons, there is no experimental evidence that exposure to cold temperatures increases the chances of getting a cold. On the other hand, several research studies show that people who exercise regularly have a significantly reduced number of respiratory tract infections, such as the common cold, compared with those who don’t exercise. Research also suggests that allergic diseases that affect the nose or throat and psychological stress may increase your chances of getting infected by cold viruses.
Common Cold:
Symptoms:
Symptoms of the common cold usually begin 2 to 3 days after infection and often include:
ADVERTISEMENTS:
1. Sore throat
2. Mucus buildup in the nose
3. Difficulty breathing through nose
4. Swelling of sinuses
5. Sneezing
6. Cough
7. Headache
8. Tiredness
ADVERTISEMENTS:
Although fever is uncommon in adults, it is often found in children with colds and can climb to 102°F in infants and young children. Cold symptoms can last front 2 to 14 days. High fever, significantly swollen glands, severe sinus pain, and a cough that produces mucus may be signs of complication or more serious illness.
Treatment:
There is no cure for the common cold, but you can get relief from your cold symptoms by
1. Resting in bed
2. Drinking plenty of fluids
3. Gargling with warm salt water or using throat sprays, or lozenges for a scratchy or sort’ throat
4. Using a decongestant or saline nasal spray to help relieve nasal symptoms
5. Using petroleum jelly to soothe a raw nose
6. Taking aspirin or acetaminophen—Tylenol, for example—for headache or fever Colds occasionally can lead to bacterial infections of your middle ear or sinuses, requiring treatment with antibios. However, antibios should not be used to treat a cold.
Prevention:
There are several ways you can keep yourself away from getting a cold of infecting others:
1. Because cold viruses can easily enter into your eyes and nose through hands, wash hands often and keep the hands away from those areas of your body.
2. 11 possible, avoid being close to people who have colds or If you have a cold, avoid being close to people.
3. When you sneeze or cough, cover your nose of mouth arid sneeze or cough into your elbow rather than your hand.
Hand washing:
Hand washing with soap and water is the simplest and one of the most effective ways to keep from getting colds or giving them to others.
Disinfecting:
Rhinoviruses can live up to 3 hours on your skin or on objects. Cleaning these environmental surfaces in your home or place of work with a virus-killing disinfectant might help prevent the spread of infection.
Vaccine:
Because so many different viruses can cause the common cold, the outlook for developing a vaccine that will prevent spreading of all of them is quite a challenge.
Alternative Medicines:
Echinacea:
Echinacea is a dietary herbal supplement that some people use to treat their colds.
Vitamin C:
Many people are convinced that taking large quantities of vitamin C will prevent colds or relieve symptoms.
Honey:
Some people use honey to treat coughs and to soothe a sore throat.
Zinc:
Zinc lozenges and lollipops are available over the counter as a remedy for the common cold. In 2009, the Food and Drug Administration warned consumers to stop using intranasal (in the nose) zinc products because some people reported a loss of smell after using these products.
