This kind of problem will not appear in the mouth of professionals, people with high school education or above, people with certain life experience, people who are numb to life, gamblers, greedy people and black-hearted people!
Therefore, it is purely for fun to ask such a question ...
People who ask questions know that the hypothesis "If the epidemic is serious, in summer ..." will not happen, that flies and mosquitoes are insects, that COVID-19 virus is spread among mammals, and that the legendary bat is a mammal, and that it will not spread among birds.
People who ask questions know the difference between viruses and bacteria. Insects spread bacterial infections, not viral infections!
The questioner, who is concerned about the change of epidemic situation, knows Zhong Nanshan's prediction that the epidemic prevention and control will end at the end of April and will not develop into summer!
The questioners are not put forward under the serious situation of epidemic prevention and control, but on the basis of remarkable achievements in epidemic prevention and control, and their intention is to stimulate people's interest in life in entertainment and popular science!
The reality is that the epidemic situation has been effectively controlled, and in many places, it is drawing to a close. As long as it is imported from outside and infected from inside, no one will be infected with COVID-19 again!
Huanggang City, Hubei Province, the hardest hit area, has seen zero growth in the number of people infected with the virus! Dawn is just around the corner ......
At the same time when breakthroughs have been made in epidemic prevention and control, many problems will naturally occur in some places and some people, and the feeling of laxity will gradually breed. The significance of raising such problems is to remind people in areas with zero epidemic growth not only to see the local areas, but also to see the overall situation, zoning, grading and classified prevention and control management!
Remind the epidemic prevention and control that when the country has not announced the end, we should not be careless and give the virus a chance to spread!
Another purpose of questioners is to attract enough attention to the spread of bacteria through flies and mosquitoes that people are familiar with!
Mosquitoes and flies, although they don't spread COVID-19 virus, can spread other bacteria and bacterial infections, which are also fatal in other countries!
the significance of asking questions is to remind everyone to develop good living habits through popular science, and neither viruses nor bacteria can harm themselves!
Use the method of dealing with COVID-19 virus to deal with flies and mosquitoes, and do a good job in personal hygiene and environmental sanitation! We can have a healthy and happy life!
Through popular science people's understanding of the importance of environmental governance and environmental protection, it can be raised to a new height!
According to the topic, do flies and mosquitoes infect viruses in summer?
For many years, flies and mosquitoes are not good things, and they are the chief culprits of wave-borne diseases. Mosquitoes suck blood and infect malaria, etc. Flies infect gastrointestinal diseases and endanger people's health.
But in midsummer, the temperature is higher and the ultraviolet rays are stronger. In the air, sunlight has poisoned us, which we can't do artificially. In addition to the low indoor temperature, as long as we pay attention to indoor ventilation and personal hygiene, this virus will soon die out, and the virus carried by mosquitoes and flies will not exist.
At present, there is no specific medicine. Let's talk about the color change of coronavirus. Now the national control has greatly improved, but we must not be blindly optimistic and pay attention to it. We expect the epidemic to end soon before summer comes. Let's take 11,111 steps back. If the epidemic continues into summer, the weather is hot and mosquitoes breed, will mosquitoes and flies become the infectious agents in novel coronavirus? To answer this question, let's take a look at the transmission channels in novel coronavirus. According to the sixth edition of novel coronavirus's guidelines for diagnosis and treatment issued by the state, the spread of new coronavirus is mainly through respiratory tract and close contact. However, the new coronavirus was also found in the feces of infected patients, and it is possible to spread through the feces in principle. Let's see if mosquitoes and flies can spread novel coronavirus. Let's take a look at mosquitoes
Mosquito-borne diseases are called insect-borne diseases, which mainly transmit pathogens to healthy people by biting sick animals or human bodies and then biting healthy people. The main diseases that mosquitoes can spread are: < P > 1. Infectious Japanese encephalitis, which is caused by viruses and mainly transmitted by Culex pipiens. Clinically, the onset period includes high fever, disturbance of consciousness, convulsion, tonic spasm and meningeal irritation.
second, dengue hemorrhagic fever, dengue fever is an acute infectious disease transmitted by Aedes mosquitoes and caused by dengue virus. The clinical symptoms mainly include fever, headache, aching muscles and joints, bleeding gums, gastrointestinal bleeding, rash and swollen lymph nodes.
3. Filariasis is prevalent in the south of the Yangtze River in China. Filariasis parasitizes in the subcutaneous tissue of lymphoid tissue or peritoneal cavity, causing lymphangitis and obstruction, with fever, acute lymphadenitis and lymphangitis in the early stage, lymphedema in the later stage, and filariasis fever in clinic.
fourth, yellow fever is an acute infectious disease caused by yellow fever virus, which is mainly prevalent in Africa and Central and South America. Its clinical features include fever, severe headache, jaundice, etc. Yellow fever has not been found in China. Since mosquitoes can infect so many diseases, can mosquitoes spread novel coronavirus? From the new guidelines for diagnosis and treatment of coronavirus issued by the state, it is not clear that the virus can spread through blood, which means that even if mosquitoes bite infected people and then bite healthy people, it will not spread. Let's talk about flies
1. Flies are hairy on the body surface, and the foot pads can secrete mucus. They like to crawl in places such as feces, urine, vomit and corpses of people or livestock for food, and it is very easy to attach a large number of pathogens, such as Vibrio cholerae, Salmonella typhi, Shigella, Hepatitis B, Polio, Hepatitis A and Ascaris eggs.
2. Flies often stay on people, food and tableware, and have the habit of rubbing their feet and brushing their bodies when they stop. The pathogens attached to them will soon pollute food and tableware.
3. When a fly eats, it spits out crop juice first, and then dissolves the food before inhaling it, and it spits and pulls while eating; In this way, the pathogen that was originally eaten in the digestive juice will be spit out together, polluting the food it has eaten, and people will get sick if they eat these foods and use contaminated tableware. We see that flies spread diseases mainly by contacting infected dirt and then carrying pathogens to people or articles, which leads to people being infected. At present, our novel coronavirus has been detected in patients' feces, which in principle may be carried by flies to healthy people and cause infection. However, the time for the virus to survive outside the human body is very short, and the probability of such infection will be very small. So how can we avoid being infected by novel coronavirus as much as possible, especially to completely eliminate the infection caused by flies?
To prevent novel coronavirus infection, experts have given detailed preventive measures, that is: go out less and gather less; Wash your hands frequently and ventilate frequently; Wear a mask and be hygienic; Sneeze, cover your mouth and nose; After sneezing, carefully rub your eyes; If you have symptoms, see a doctor early.
I want to tell you emphatically that to prevent virus infection caused by flies and mosquitoes, we must pay attention to personal hygiene, wash our hands frequently, do not pick your nose and rub your eyes when your hands are dirty, and do not eat cold food or drink cold water. To sum up, if the epidemic can last until summer, the probability of transmission by mosquitoes and flies in novel coronavirus is very small. We can also firmly believe that with the strong support of the CPC Central Committee, the earnest implementation of local governments at all levels, and the efforts of medical staff and other Qian Qian compatriots, the epidemic will soon end!
With the coming of summer, many people worry that Covid-19 will be spread by mosquitoes and flies.
In response to this concern, researchers from the Beijing Center for Disease Control and Prevention said that there is no evidence that mosquitoes and flies spread in Covid-19. Covid-19 is mainly spread by air and contact. The virus can be spread by droplets of patients, or by touching contaminated articles used by virus carriers and touching eyes, mouth and nasal mucosa. But mosquitoes and flies can spread other infectious diseases, such as malaria and dengue fever. She reminded people to take measures to prevent mosquito bites in summer and pay attention to properly protect food.
According to the latest research, high temperature may hinder the spread of Covid-19, but it will not completely kill it. First of all, the current global outbreak of COVID-19 shows that high temperature can't stop its spread, and COVID-19 has spread to countries with higher temperature, such as Singapore, Malaysia, Australia and almost all African countries. The World Health Organization has also assessed that Covid-19 may spread to hot and humid areas.
At present, the epidemic is spread by gas, which has nothing to do with mosquitoes and flies, which will cause panic. Believe in science.
it's hard for the virus to survive in summer, isn't it, not to mention that the virus can't survive in a high temperature environment? Just like few people catch a cold in summer!
personally, I don't think so! Mosquitoes and flies are there every day! Do a good job of hygiene and cleaning! Don't post it indiscriminately.
