This year may not be just me, everyone should be very scared.

I don't know when a disease suddenly appeared, and in this Spring Festival, it became familiar to everyone all of a sudden.

Not just because of its extremely high mortality rate, but also because of its ultra-fast infection rate.

It infected many parts of China at once, and brought a sudden shock to this new century.

The school issued an urgent notice, many high-speed trains were suspended, and even the movie tickets I had bought were refunded to me.

People are anxious and rush to the supermarket to buy daily necessities, and the supermarket is also very panicked, and people who come and go have thermometers to measure them.

People wearing masks on the road panicked, fearing that the people who passed by around them were the ones with the virus on their bodies.

My mother and I went out on the street, wearing thick masks, looking at the slightly desolate street.

Mother said that this situation was just in time for SARS that year.

But at the time of SARS, I was still young and didn't remember, so I didn't have any big impressions.

So this is still the most terrible national disaster I have ever felt since I was a child.

I don't know what you think, but I think the severity of this matter can be regarded as a catastrophe in China.

This catastrophe came unexpectedly and dealt a blow to many of us.

I heard that the source was wild bats that were eaten by people, and I heard that it was wild other things, and I heard that it was uncooked seafood.

However, it is a little too late to find out the source, and we should think more about how to control the current situation.

I think the virus is terrible, the disease is terrible, but what really makes everyone fight is because of the fear in the heart.

I'll tell you a little bit about the coronavirus.

Novel Coronavirus (2019-

CoV) infection

At first, fever, fatigue, dry cough, and gradually difficulty breathing

Have the ability to infect people, and wear masks correctly to strengthen protection

Most have a good prognosis, while a few are critically ill and can even lead to death

Disease definition

Pneumonia caused by the novel coronavirus is an acute infectious pneumonia whose causative agent is a novel coronavirus that has not been previously found in humans, namely the 2019 novel coronavirus (2019

ovel Co

o

avi

us，2019-

CoV）。

Patients usually have initial symptoms of fever, fatigue, and dry cough, followed by severe manifestations such as dyspnea. Most patients have a good prognosis, and some severe cases may develop acute respiratory distress syndrome or septic shock, and even death. Currently, there is no specific treatment for the disease.

The latest epidemiological data show that the incubation period of the disease is about 10 days, the shortest incubation period is one day of onset, and the longest incubation period is 14 days, and the incubation period is contagious. The disease is mainly transmitted through droplets and contact, and according to the previous SARS transmission mode, there may be a risk of aerosol transmission in closed and unventilated places, and prevention and isolation treatment need to be strengthened.

epidemiology

The first case of pneumonia caused by the novel coronavirus was found in Wuhan City, Hubei Province on December 12, 2019, and most of the subsequent patients had a history of exposure to the Huanan Seafood Market or family gatherings.

At 9:00 p.m. on January 7, 2020, researchers detected a novel coronavirus in patient specimens;

At 24 o'clock on January 10, the pathogen nucleic acid test was completed;

On January 12, the World Health Organization (WHO) named the novel coronavirus that caused the Wuhan pneumonia outbreak as the 2019 novel coronavirus (2019-

CoV）；

As of 24:00 on January 25, the National Health Commission has received a total of 1,975 confirmed cases from 30 provinces (autonomous regions and municipalities), and there are 324 severe cases. A total of 56 cases have died, and 49 cases have been cured and discharged. There are currently 2,684 suspected cases. A total of confirmed cases have been reported from Hong Kong, Macao and Taiwan: **5 cases in the Special Administrative Region, 2 cases in the Macao Special Administrative Region, and 3 cases in Taiwan, China. In addition, a total of confirmed cases have been reported from abroad: 4 cases in Thailand (2 cases have been cured), 2 cases in Japan (1 case has been cured), 2 cases in South Korea, 2 cases in the United States, 2 cases in Vietnam, 3 cases in Singapore, 3 cases in Malaysia, 1 case in Nepal, 3 cases in France, and 1 case in Australia.

The most common problems of patients

What are the symptoms of a person infected with the novel coronavirus?

The severity of symptoms after infection with the novel coronavirus depends on the type of virus and the level of immunity of the human body, the common ones are fever, cough, shortness of breath or difficulty breathing, and in more severe cases, it can lead to acute respiratory distress syndrome, septic shock, etc., which can lead to death.

Can the novel coronavirus spread from person to person?

Yes, the novel coronavirus can be transmitted from person to person, usually in homes, workplaces, crowded areas, or hospitals.

Is there currently a vaccine against the novel coronavirus?

No, it can take many years for a vaccine to be developed for an emerging disease.

Is there a cure for the novel coronavirus?

There is currently no specific treatment for diseases caused by novel coronavirus infection, and clinical treatment is mainly symptomatic supportive treatment.

Are healthcare workers threatened by the novel coronavirus?

Yes. Healthcare workers need to be in close contact with patients and are more vulnerable to the threat of infection from the novel coronavirus. Therefore, the World Health Organization (WHO) recommends that healthcare workers strengthen their own infection prevention and control measures. Strictly implement the standard precautionary principles, do a good job of personal protection and hand hygiene, and avoid nosocomial infections as much as possible.

Underlying causes

Coronaviruses belong to single-stranded positive-strand RNA viruses, and there are 6 coronaviruses that have been known to infect humans in the past, namely HCoV-229E, HCoV-OC43, and SARS

- CoV, HCoV-NL63, HCoV-HKU1, and MERS

-CoV。 The disease was caused by a novel coronavirus that had not been previously found in humans, namely the 2019 novel coronavirus (2019-

CoV), which belongs to the 7th category.

Predisposing factors

The elderly and those with underlying medical conditions are prone to become critically ill after infection.

The main manifestations are fever, fatigue, dry cough, and gradually dyspnea.

Patients with mild disease have only upper respiratory tract infection.

Severe and critically ill patients may have acute respiratory distress syndrome, septic shock and other manifestations.

Typical symptoms

Fever, fatigue, and dry cough are the main manifestations;

Upper respiratory tract symptoms such as nasal congestion and runny nose are rare;

About half of patients develop dyspnea after more than one week;

High fever is less, about 38 degrees, some can have no fever, and the disease can progress in about 7~10 days;

In severe cases, it rapidly progresses to acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, and coagulopathy;

Severe and critically ill patients may have moderate to low fever or even no obvious fever during the course of the disease;

Most patients have a good prognosis, and a few are critically ill and can lead to death.

The disease is an acute infection that usually progressively worsens during the first week, so seek medical attention if:

Recent unexplained fever, fatigue, cough, etc.;

History of residence or travel to Wuhan within two weeks prior to the onset of illness;

History of close contact with the confirmed patient two weeks prior to the onset of illness;

Clustered onset (2 or more people).

During your appointment, your doctor will ask you the following questions to get an initial overview of your medical history, and you may be prepared to answer them in advance:

When do symptoms such as fever and cough appear?

Where did you go and who did you come into contact with before you became ill?

Is there anyone close to you who has similar symptoms?

Do you have trouble breathing?

What are the underlying medical conditions?

Daily life management

It is practical to pay attention to wearing masks in public places and strive to do a good job of personal protection;

Practice hand hygiene, wash your hands frequently, wash your hands with soap or water, or hand sanitizers that contain alcohol;

Pay attention to proper cough etiquette, do not cover your sneeze with your hands, and cover it with your elbow or tissue;

Pay attention to drink more water, rest more, avoid staying up late, and improve individual immunity;

Maintain ventilation in the living and working environment;

Eat wisely, cook meat and eggs thoroughly when cooking, and avoid unprotected contact with wild animals and poultry;

Don't go to crowded places and avoid close contact with anyone with cold or flu-like symptoms.

Daily condition monitoring

Pay attention to monitor body temperature, and seek medical attention if you have fever, fatigue, cough and other symptoms. If you have a history of living or traveling to the epidemic foci (Wuhan City) within two weeks before the onset of illness, have a history of contact with confirmed or suspected patients, or have collective symptoms, you need to seek medical attention in time and take the initiative to isolate.

Special considerations

The incubation period of the disease can be 1~2 weeks, if there is a history of contact with confirmed or suspected patients, even if there is no fever and other symptoms temporarily, it is necessary to actively isolate.

To be released from isolation, the body temperature needs to return to normal for more than 3 days, the respiratory symptoms have improved significantly, and the pathogen test has been negative for 2 consecutive times (at least 1 day apart).

prophylaxis

For the time being, there is no effective vaccine to prevent pneumonia caused by the new coronavirus.

Personal protection is the most practical way to do this, including not going to crowded places, washing hands frequently, drinking plenty of water, and taking rest.

The recent pneumonia has made people panic, but I think the more you are at this time, the more calm you are, don't panic, first of all, wear a mask when you go out, drink plenty of water regularly at home, keep enough sleep, eat lightly, don't eat spicy food, it's easy to get angry, and maintain a good attitude.

Regarding the recent pneumonia, I would like to say that it is useless for everyone to discuss who is right and who is wrong here, as ordinary people, the only thing we can do is to cooperate, listen to official news, do not spread the word, do not follow the trend, do not cause panic, pay attention to yourself, do a good job of protective measures, spring will always come, and my Greater China will definitely survive! I am in Hebei, cheering for the medical staff who are struggling on the front line! Cheer for Wuhan! Cheer for China! ❤️❤️❤️
