Anonymous users2024-02-12JE, also known as Japanese encephalitis, is mainly transmitted by mosquitoes and mosquitoes, which are mainly common in summer and autumn, so summer and autumn are the high incidence seasons of JE. Mosquitoes may bite bats, lizards, snakes and other animals in winter, animals will carry the virus in winter, and mosquitoes will re-bite these animals in summer, re-carry the virus, and then bite domestic animals such as pigs and cattle, so that pigs and cattle have transient viral blood disease and hidden infection. If more mosquitoes bite humans, Japanese encephalitis can be transmitted.

Anonymous users2024-02-111.Disease Course A typical course of the disease can be divided into the following 4 stages.
1) Initial stage: 3 days at the beginning of the disease, that is, the viremia stage, acute onset, generally no obvious prodromal symptoms, fever, malaise, loss of appetite, mild drowsiness, large children can complain of headaches, infants and young children can have diarrhea, the body temperature is about 39, and it does not go away, at this time, the neurological symptoms and signs are often not obvious and mistaken for the upper sense, and a small number of patients have apathy, irritation or mild neck resistance.
2) Extreme stage: the course of the disease is 3 10 days, in addition to the aggravation of systemic blood toxicity symptoms, the symptoms of brain damage are prominently manifested in this stage.
3) Convalescence period: At this time, the patient's body temperature can gradually drop and return to normal in 2 5 days, the consciousness disorder begins to improve, the coma patient gradually becomes awake after a short period of mental sluggishness or indifference, the pathological signs of the nervous system gradually improve and disappear, some patients recover slowly, it takes more than 1 3 months, severe patients due to severe brain tissue lesions, the symptoms of the convalescence period can be manifested as continuous low-grade fever, excessive sweating, insomnia, sluggishness, slow response, mental and behavioral abnormalities, aphasia or particularly many words, dysphagia, Symptoms such as ankylosing paralysis or involuntary movements of limbs, epileptiform seizures, etc., can recover after half a year after active **.
4) Sequelae period: sequelae and JE lesions are closely related, sequelae mainly include consciousness disorders, dementia, aphasia and limb paralysis, etc., if positive, there can also be different degrees of recovery, coma sequelae patients long-term bed rest, can be complicated by pneumonia, bedsores, urinary tract infection, seizure sequelae can sometimes last for life.

Anonymous users2024-02-10Answer] :d Japanese encephalitis is an infectious disease caused by the Japanese encephalitis virus, which is transmitted by mosquitoes and is more common in summer and autumn.
-
Anonymous users2024-02-09Answer] :d analysis: The transmission route of Japanese encephalitis is mainly transmitted by mosquito bites.
Error avoidance] The source of Japanese encephalitis infection is pigs and other domestic animals and poultry carrying the virus of the disease, and Japanese encephalitis patients are of little significance as the source of infection. Culex mosquitoes, Aedes mosquitoes.

Anonymous users2024-02-08Answer] :d analysis: The main sources of infection of hemorrhagic fever with renal syndrome are Haddock rats and Brown rats, and in forest areas, they are mainly Rats (b).
The main source of infection of Japanese encephalitis (JE) is piglets, because almost 100% of piglets are infected after an epidemic season, and the number of viruses in the blood after infection is large, and the viremia period is long; Coupled with the wide range of pigs, pigs are the main source of JE infection (D).

Anonymous users2024-02-07Answer]: C test center: the source of infection of Japanese encephalitis; Analysis:
The main source of infection of Japanese encephalitis is domestic animals and poultry, mainly pigs (almost 100% of piglets are infected after an epidemic season), followed by horses, cattle, sheep, dogs, chickens, ducks, etc. Among them, the young pigs that have not passed the summer are the most important. Animals can have viremia for 3 to 5 days after infection, and mosquitoes can be infected and spread by starvation.
Therefore, C is selected for this question. Error avoidance: It is easy to mistakenly choose A in this question.
JE is a zoonotic disease, and wild patients and many animals can be the source of the disease. Pigs have the highest infection rate in animals, and poultry do not have a high infection rate in pigs, and the number of viruses in the blood after infection is large and lasts for a long time, so pigs are the main source of infection of the disease, so C is selected for this question.

c.Adult cats.
d.Japanese encephalitis carriers.
e.Lice when bacteria invade.
Correct Answer: Faith Crack B
Immunodiffusion and enzyme-linked immunosorbent assay (ELISA) are used to detect all antibodies against epidemic virus in poultry type A, but this diagnostic method cannot distinguish between subtypes, and haemagglutination inhibition reaction (HI) must be used to determine haemagglutination antigen (HA), neuranomidase antigen (NA) by neuraminidase inhibition reaction (NI) to determine the prevalent ** virus subtype. >>>More
Air, saliva, blood, baths, sweat, pets carrying pathogens, in short, objects that can come into contact with pathogens!
Hookworm is a disease caused by hookworms parasitic in the small intestine of the human body People with hookworm and those infected with hookworm are the source of infection; Infection between fingers and toes is the most common site of invasion; In areas where there is a habit of eating raw vegetables, it can be transmitted by mouth People are generally susceptible to hookworms Generally more young adults There are fewer children Most male patients In China, the hookworms parasitic on the human body are mainly duodenal hookworms and American hookworms Prevention of hookworm disease [Prevention] 1In the susceptible season, when the morning dew is not dry or the first sunny day after the rain, avoid contact with crops infected with hookworms, and wear rubber shoes, protective gloves, or topical protective agents such as 2% iodine solution and 25% alum solution when the site must workAfter being infected with hookworms, the sputum coughed up should not be swallowed; 3. Pay attention to environmental hygiene and strengthen fecal management.
Polio is mainly transmitted through fecal-oral transmission, with the virus being excreted through the patient's nasopharynx at the beginning of infection, and then excreted in the feces as the disease progresses. In general, the virus can be carried in the feces for several months and can be transmitted by contaminating water, food and other daily necessities. In addition, oral live attenuated vaccines, after being excreted in the stool, have the potential to regain virulence in the external environment and infect other susceptible people.
