Write a 400-word composition according to the epidemic situation.

1. How to write an essay about coronavirus in 400 words Spring Festival is a festival of family reunion and family happiness, and it is a festival full of vitality and saving strength for the coming year. But a sudden novel coronavirus, which originated from wild animals, forced the people of the whole country to cancel their original plans, disrupted all the life rhythms and washed everything apart like a sudden flood.

This epidemic has brought disaster, panic and lessons! The bustling streets are particularly depressed. Occasionally, a few cars fly by, and they seem to run faster than usual, as if they were followed by the claws of the virus. Mom and dad said that staying at home now is to contribute to society. Occasionally standing at the window, looking at the outside world, my heart is full of infinite yearning.

When this epidemic is over, I will return to a school full of joy and wisdom. In the bright classroom, study hard with classmates; On the wide playground, run hard with classmates; Corridor between classes, talking and laughing with classmates.

After the epidemic, my parents and I will walk to the patio lake, the wetland park, climb the Tongguan Mountain, feel the embrace of nature, breathe fresh air and enjoy the warm sunshine.

After the epidemic has passed, I want to say to the amiable and respectable angels in white people: "Uncle and aunt, you have worked hard. You are the most respectable people and an example in our hearts! "

I firmly believe that the great motherland will certainly overcome the plague and give us a sunny tomorrow. Come on Wuhan, come on China!

2. Ebola virus composition 400 words Ebola virus has been given a terrible title in West Africa-"death", which is a nightmare for people in West Africa. The report about it will also keep some people awake at night, and I am one of them.

That night, as usual, I turned on the TV and watched the news. At the scene, I saw the latest situation about the Ebola epidemic: "Two professional medical staff who went to the epidemic area from the United States were infected with Ebola virus", "More than 400 infected people died, and more than half of them were infected" ...

I'll go. Professionals wearing chemical protective clothing are infected and the mortality rate is so high. In case this thing comes to China ... I dare not think about it again. Change the channel immediately and distract yourself. But the painful expression of the infected person, the Ebola virus possessed by death under the microscope, still lingers in my mind.

Forget it, wash and sleep, and you won't be so scared when you fall asleep. I comforted myself by saying that I turned off the TV and went to wash and sleep.

Lying in bed, tossing and turning is not sleepy at all. What about breaking into infected people at night? Well, I'd better cover myself with a quilt, at least to increase my sense of security. It's very hot in dog days. I slept under the quilt and soon I was sweating.

I feel panic for no reason. Isn't sweat a body fluid? I seem to remember that contact with patients' body fluids is also a mode of transmission, right? Although I know very well that my sweat has nothing to do with it, I still have a sense of fear in my heart. It was more than half an hour before I managed to fall asleep.

I woke up and found that everyone around me was infected with Ebola and came to me with blood. I couldn't help screaming and immediately sat up-oh, it was a dream. Look at the alarm clock, it's only midnight 12 o'clock.

Afraid to sleep again, I grabbed some books by the bed and read them. Tired of watching, I narrowed my eyes, and the scene in my dream suddenly came back to my mind, so I opened my eyes again and continued reading.

After reading some books, it is already five o'clock in the morning. At this time, my heart is not so panic. Calm down and sort out the contents of the news, and think of two points: first, the speed of contact and communication will be slower; Secondly, he said it was unlikely to spread to China.

Ha, so much ado about nothing! My mouth rose slightly, my head lay down, and I fell asleep. I didn't know the east was white.

3. Composition for preventing infectious diseases Spring is the season when everything recovers. But spring is also a season of frequent infectious diseases. Students, do you know how to prevent infectious diseases? First, after studying, we should develop good living habits and regular schedules, and maintain a happy mood. We should take an active part in fitness activities, such as skipping rope, jumping and playing ball. Only when our bodies are strong can diseases take advantage of it. Second, pay attention to the weather changes, change clothes at any time, keep warm and avoid catching a cold. Third, we must ensure adequate sleep. Because of fatigue, it is easy to reduce our resistance. Washing feet with hot water before going to bed is beneficial to sleep and relieve fatigue. Fourth, to prevent colds in spring, we should first pay attention to diet, which should be light and easy to digest, and eat more protein and vitamins. Don't be partial to food, usually eat more fruits and vegetables, and don't be cold. Students, let's take action to protect our health.

I read the composition on infectious diseases. Everyone looks pale at the mention of SARS.

Because SARS once made countless families in China go wherever they went. Speaking of the power and infection speed of SARS, it is really chilling, but no matter how powerful the virus is, it will eventually be overwhelmed by the great spirit of the Chinese nation: SARS will soon disappear.

Now people are happy and are no longer troubled by SARS. However, when people were unprepared, the door of death was knocked open again-meningitis appeared. What is epidemic cerebrospinal meningitis? How to spread? How are the symptoms? A series of problems followed.

"Meningitis" is purulent meningitis caused by meningococcus. The "epidemic cerebrospinal meningitis" virus is hidden in the nasopharyngeal secretions of patients, and it spreads directly from the air through droplets such as coughing, sneezing and talking, and enters the respiratory tract to cause infection.

Once an infection is caused, if it is not rescued in time, the consequences will be unimaginable. The general symptoms are sudden high fever, severe headache, frequent vomiting, listlessness, stiff neck and even coma and convulsions.

"Meningitis" generally tends to children under 15 years old, and the illness is often divided into two types: ordinary type and explosive type, which often leads to death within 24 hours. Because of its high concealment, it is often mistaken for the common cold, which delays the diagnosis and treatment period and even endangers life.

We should conquer epidemic cerebrospinal meningitis with the great spirit of our nation. People often say that "everything has its vanquisher".

Encephalomyelitis is no exception. As long as preventive work is done, the "encephalomyelitis" virus will never visit our bodies again. The prevention of "epidemic cerebrospinal meningitis" is mainly to pay attention to ventilation, maintain personal hygiene, get more sunshine and eat reasonably.

I believe that as long as we remain vigilant, nip in the bud and unite as one, the sun will shine forever! Let health spread all over the country, let smiles hang on your cheeks, and let happiness last forever.

I think infectious disease is a terrible word for some people, because it can infect each other through various channels, so people are afraid and stay away from it.

In my opinion, infectious diseases are not terrible, the key is what kind of mentality you use to look at it. Let's say that our most common infectious disease, influenza, has been plaguing people's health since ancient times.

In ancient times, it could threaten people's lives. However, our ancestors did not give in, but tasted all kinds of herbs and finally conquered it with ordinary herbs. Since the invention of chemicals, although it sometimes patronizes our bodies, we are fully capable of subduing it, and it can no longer be violent.

Let's talk about the severe SARS in our country in 2003, because there has never been such a medical history in history, so it is more difficult to treat. However, angels in white, the Chinese nation, was not intimidated, but fought against it with perseverance.

Although no cure for SARS has been found yet, after all, all SARS patients have been discharged from hospital smoothly and returned to work, and SARS has finally been overwhelmed by the spirit of the Chinese nation's unity and never forgetting death. On this day in 2005, "epidemic cerebrospinal meningitis" once again visited our beautiful home.

But can we be conquered by him? Don't! Absolutely not! Although "epidemic cerebrospinal meningitis" has a high mortality rate, it is a loser after all. Humans have formulated a plan to subdue it, as long as we take precautions, actively inject vaccines, achieve early detection, early isolation and early treatment, and face it with an optimistic attitude. I firmly believe: mankind will certainly defeat it! Human science is constantly developing, and no natural or man-made disaster can stop its development.

What's so terrible about just infectious diseases? Let's hold our heads high to meet the new challenges.

6. Who can write a composition with novel coronavirus? Time flies 400 words, and the sun and the moon fly like a shuttle. In a blink of an eye, the Year of the Pig has quietly left, and we are about to usher in a new year, the Year of the Rat! Of course, the New Year also has the Spring Festival. The long-awaited Spring Festival can count lucky money with red envelopes. In the past, shopping malls were very busy during the New Year, and everyone was busy buying new year's goods. Now the cold door is tightly closed. The road where cars used to come and go is now empty; Firecrackers, which used to ring all day and all night, are now extremely silent; In the past, everyone was happy to visit relatives; Now, I stay at home, never leaving home; Brand-new Spring Festival clothes; Now it's a mask. All these are because of the outbreak of novel coronavirus, and everyone is afraid to go out, but the medical staff all over the country have no hesitation to visit the sick people in order to control the further spread of the virus. As the epidemic situation becomes more and more serious, more and more patients are diagnosed. Many places have adopted the method of closing cities and townships to strictly check the entry and exit of vehicles. Later, I checked my mobile phone, and it turned out that it was because of some people's appetite. Eating bats and other wild animals tells you that novel coronavirus hosts not only bats, but also rabies, Hendra virus "Hanta" virus and other viruses. My brother was born in this novel coronavirus outbreak. Looks like he's here to fight the virus. I cheer for those angels in white who are fighting the disease!
