Second, there are also non-statutory infectious diseases: common such as: chickenpox, genital herpes, tuberculosis pleurisy, reproductive tract Chlamydia trachomatis infection.
Question 2: What are the more powerful infectious diseases in human history Smallpox (Smallpox)
As early as the 16th century, European explorers, colonizers and conquistadors have not yet entered the New World before the continent of the Americas has been inhabited by nearly 100 million indigenous people. But within the next 100 years, outbreaks of infectious disease plummeted the population to 5 to 10 million. Although some of these native peoples, such as the Incas and Aztecs, had begun to build cities. But because of their short time, they had not yet domesticated animals in large numbers, nor had they yet bred many of the germs that infested the Europeans. But with the arrival of the European colonizers, many infectious diseases that the indigenous population could not resist came to the New World.
The worst of these infectious diseases was smallpox. Smallpox germs have been spreading through human societies for thousands of years, and the most powerful of these diseases cause a 30 percent mortality rate. Symptoms of smallpox include high fever, generalized body aches, rashes, blisters, and permanent scars. The disease is typically spread through direct contact with the patient's skin or body fluids, but it can also be airborne in closed environments.
Although a smallpox vaccine was available in 1796, the virus continued to spread. Even in 1976, smallpox caused 20,000 deaths and panic among millions of people worldwide. In the same year, the World Health Organization (WHO) began to introduce mass vaccination against smallpox, and in 1977, cases of smallpox disappeared completely. Today, the virus is nowhere to be seen in nature except in laboratories.
Spanish influenza
In 1918, at the end of the First World War, 37 million people around the world were killed in the war, and millions of soldiers began to return home. That's when a new type of disease emerged, which some call the Spanish flu, or the pandemic of the century and the 1918 flu. It took the lives of 20 million people in a matter of months. Over the course of a year, the flu continued to spread and the death toll was staggering. It is estimated that between 50 and 100 million people died worldwide from this epidemic. The flu was considered the worst plague ever to hit mankind.
The Spanish flu was different from the common flu we now experience every year. It was a new type of flu virus, known as the H1N1 avian flu virus. Scientists suspect that this virus was transmitted to humans from birds in the American Midwest before World War I. It is now known as H1N1. It later killed 8 million people in Spain, and the flu became known as the "Spanish flu". Globally, most humans were completely defenseless against the virus, just as the Aztecs were in 1550 when they faced smallpox. Massive transportation and resupply forces made the spread of the virus to other regions even more rapid.
The 1918 flu also had the typical symptoms of the common flu, such as fever, nausea, abdominal pain, and diarrhea. Similarly, patients often had dark spots appearing on their faces and fluid-filled lungs, which could easily lead to hypoxia, and patients with the disease often died from fluid-filled lungs.
This flu slowly disappeared a year later as the virus mutated and shifted toward being non-lethal. For us, we are all resistant to the H1N1 family of viruses due to genes and some inherited antibodies.
Black Death
Carts piled high with corpses, boards filled with dead family members, and nobles and peasants wailing in unison, hoping to enter heaven and be freed. This was the Black Death, the most horrific epidemic in human history. The Black Death is considered to be the first true mass epidemic of a contagious disease. in Europe in 1348, half of the population died from the Black Death. At that time, many people in China and India also died from it. The Black Death continued to spread along the routes of war and trade, completely destroying cities and villages along the way, and dealing a fatal blow to politics and economics across the globe.
The Black Death was long thought to be an epidemic plague, spread by fleas on rats and through the air. But recent research has challenged this. Some scientists believe the Black Death may be a hemorrhagic virus similar to Ebola. Scientists are studying the bones of suspected plague victims in hopes of finding some genetic evidence to confirm the theory.
If the Black Death was the bubonic plague, it still exists. Plague, caused by the bacterium Yersinia pestis, still occurs today in some of the poorer areas where rats are infested. But it can be greatly reduced with some simple treatment in the early stages of the disease. The main symptoms of this disease include swollen lymph glands, fever, cough, bloody sputum and difficulty in breathing.
Plague
Malaria is not a new infectious disease. The earliest accounts of malaria appeared 4,000 years ago, when the Greeks chronicled its devastating effects. The earliest references to mosquito-borne diseases appeared in ancient Indian and Chinese medical texts. Even now, scientists ...... >>
Question 3: What are the most significant infectious diseases in human history Foot and Mouth Disease reduced the UK's economic growth that year to 2% from the original forecast of 2.3%, resulting in an economic loss of ￡7 billion. One of the mainstay industries, tourism, was hit hard. It was reported that tourism revenue in the UK countryside alone had dropped by 75% compared with the same period in 2000. SARS In 2003, an outbreak of atypical pneumonia occurred in 24 provinces, autonomous regions and municipalities in the Mainland of China, **** affecting 266 counties and cities (districts). As of 10:00 on August 16, a total of 5,327 clinically diagnosed cases of atypical pneumonia had been reported in the Mainland of China, with 4,959 cases cured and discharged from hospitals, and 349 deaths.Tourism revenue decreased by about 120 billion yuan in 2003, affecting the annual GDP growth by 1.1 percentage points less. Retail sales of restaurants decreased by about 31.5 billion yuan, affecting GDP growth by 0.3 percentage point. The overall impact on other consumer goods was smaller, at around 20 billion yuan, affecting GDP growth by 0.2 percentage points. Net foreign trade exports were about $7 billion less than in 2002. Bird Flu So far 393 people from 15 countries and regions around the world*** have been infected, of which 248 died, with a mortality rate of 63%. In China, 31 people have been infected with avian influenza since 2003, of whom 21 died. in early 2004, avian influenza swept through the United States and parts of Asia, with millions of poultry in China, Japan and Vietnam dying of the disease, and many people may have died as a result of being infected by the avian influenza virus. By 2005, avian influenza had caused the culling of more than 150 million birds worldwide, 63 deaths, and direct economic losses amounting to US$10 billion. The scope has spread to agriculture, tourism and other industries. The World Bank predicts that avian influenza will cause global economic losses of up to US$800 billion. What is Avian Influenza? Swine Flu Mainly in Mexico, confirmed and suspected swine flu deaths rise to 152; up to 4,000 suspected cases nationwide. The number of confirmed cases in the U.S. has risen to 50, with additional cases in 19 countries including Canada, the United Kingdom, France, Germany, South Korea, New Zealand, Australia, and Italy. The World Bank predicts a global loss of $3 trillion and a major impact on economic recovery. There are two ways in which swine flu is most likely to spread, from pigs to people and further from people to people.
The Black Death In the 14th century, a pandemic of the bubonic plague, then known as the "Black Death," spread throughout Asia, Europe, and northern Africa, and also in China. In Europe, the Black Death was rampant for three centuries, claiming the lives of more than 25 million people. The germs that caused the plague were carried by fleas hidden in the fur of black rats. In the 14th century, black rats were abundant. Once the disease occurred, it spread rapidly. So many people died from the Black Death that there was a shortage of food for the labor force. Whole villages were abandoned, farmland fell into disuse, and food production declined. The Black Death was followed by famine in many parts of Europe. Spanish Influenza The catastrophe caused by the Spanish influenza pandemic was the most serious one in the history of influenza epidemics, and it was also the plague with the largest number of deaths in the history, and it was estimated that the number of sick people in the world was more than 700 million, and the morbidity rate was about 20%-40%, and the number of deaths amounted to more than 4,000,000-50,000,000 people. Research by U.S. scientists has shown that the Spanish flu virus that killed 50 million people in 1918-1919 probably originated in birds. It is actually a mutation of the bird flu. Similar to the Black Death, during the flu, transportation, restaurants, retail, tourism and entertainment were depressed, with hospitals and health services being the biggest winners. It is worth noting that the communications industry was well developed. Mad Cow Disease The main country of origin is the United Kingdom. The death toll is estimated to be rising annually at a rate of about 30% per year, with 69 deaths to date. It has spread to France, Ireland, Canada, Denmark, Portugal, Switzerland, Oman, Germany, Poland, Czech Republic, Hungary, Slovakia, Albania, Estonia, Lithuania and Cyprus. CNN estimates that the mad cow disease outbreak will have cost the U.S. at least billions of dollars in economic losses. Foot and Mouth Disease In 2001, an outbreak of Foot and Mouth Disease (FMD) in the United Kingdom resulted in the centralized slaughter and burning of nearly 7 million FMD-infected livestock, with many farmers suffering heavy losses. Most countries in the world, such as the United States, Canada, Japan, South Korea, Australia, New Zealand and some European countries, etc.; Southeast Asian countries, Hong Kong, China, mainland China, etc. are "foot-and-mouth disease infected area"

Please adopt
Question 5: The latest statutory infectious diseases a **** 40 kinds, please ask the A B C three categories are respectively what? The types of statutory infectious diseases in China are divided into categories A, B and C, *** three categories of 39.
Category A 2 kinds, including: plague, cholera.
Category B 26 kinds of infectious diseases, including infectious atypical pneumonia, AIDS, viral hepatitis, poliomyelitis, human infectious pathogenic avian influenza, influenza A (H1N1), measles, epidemic outbreaks of snow fever, rabies, epidemic encephalitis B, dengue fever, carbonic gangrene, bacillary and amoebic dysentery, tuberculosis, typhoid fever and paratyphoid fever, epidemics of cerebral and spinal meningitis, pertussis, diphtheria, neonatal tetanus, scarlet fever, brucellosis, gonorrhea, leptospirosis, schistosomiasis, and malaria.
Category C infectious diseases 11, including: influenza (referred to as influenza), mumps, rubella, acute hemorrhagic conjunctivitis, leprosy, epidemic and endemic spotted typhoid fever, black fever, borreliosis, filariasis in addition to cholera, bacillary and amoebic dysentery, infectious diarrheal diseases other than typhoid fever and paratyphoid fever, hand, foot, and mouth disease.
Question 6: What are the **** same characteristics of infectious diseases Intestinal infectious diseases have the same transmission pathway, are transmitted by fecal - oral transmission, the patient's feces and vomit carries a large number of pathogens, which contaminated water, food, hands, utensils or flies and other vectors to carry contaminated bacteria into the gastrointestinal tract of the healthy people. Caused by the onset of clinical symptoms, in addition to polio, most have varying degrees of diarrhea and other gastrointestinal manifestations. In addition, these infectious diseases are highly contagious, there is a risk of outbreaks and epidemics, so it should be a high priority.
Question 7: What are the characteristics of infectious diseases? I only found 5 I hope it can help you
The characteristics of infectious diseases include the following 5 aspects:
① There are pathogens: each infectious disease has its specific pathogens, including microorganisms and parasites. For example, the pathogen of chickenpox
is chickenpox virus, and the pathogen of scarlet fever is hemolytic streptococcus. Pathogens are mainly categorized into bacteria, viruses (smaller than bacteria
, cell-free structure), fungi (the agent of ringworm), protozoa (malaria protozoa), helminths (the agent of helminthiasis).
② contagious: the pathogen of an infectious disease can be transmitted from one person to another through a certain route. Each infectious
disease has a relatively fixed period of contagion, discharging pathogens, contaminating the environment and infecting others.
③ have immunity: most patients can produce different degrees of immunity after the disease is cured. The body can produce specific immunity after infection with pathogens
. Post-infection immunity is autoimmunity.
④ can be prevented: through the control of infectious sources, cut off the infectious pathway, enhance the resistance of people and other measures, can effectively prevent
prevention of infectious diseases and epidemic.
⑤ Epidemiological characteristics: infectious diseases can be prevalent in the population, the epidemic process by the influence of natural and social factors
, and show a variety of epidemiological characteristics.
