Loss of liver function are one culprit - Viral Hepatitis
To remind
incidence throughout the year may be in order for the incidence of autumn and winter peak
Often distributed
Type A, hepatitis E in fecal - oral transmission; B,
Hepatitis C, hepatitis D major by the spread of blood and blood products
mainly for fatigue, loss of appetite, nausea, abdominal distention,
Hepatomegaly and abnormal liver function, some patients may be jaundice,
Also has a considerable number of patients asymptomatic; alpha, hepatitis E

In 1988, the Shanghai hepatitis A occurred in a pandemic, the number of infections reached more than 30 million, shocking the country. So, what is hepatitis A do? What are the types of hepatitis this? Usually described as "hepatitis", generally refers to infectious viral hepatitis, are caused by the hepatitis C virus a group of diseases. has now been confirmed cause of infectious hepatitis has five kinds of viruses, namely A, B, C, D, hepatitis E virus. were caused by a hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV), hepatitis D (HDV) and hepatitis E (HEV). arising from the Shanghai hepatitis A major culprit is a popular liver virus, because people are eating contaminated by hepatitis A virus-induced Scapharca. have been found apart from the A, B, C, D, hepatitis E virus, with the development of science and technology will have a new hepatitis virus was found, was named.
Showed the distribution of viral hepatitis worldwide. Our country is a high incidence of hepatitis, hepatitis B for one of the most threatening people's health. China's hepatitis B surface antigen-positive, about 120 million, representing the world's hepatitis B virus infection in the total number of 1 / 3. one of chronic hepatitis B patients about 30 million chronic hepatitis B patients 10% 30% may develop liver cirrhosis, about 5% of the development of liver cancer. viral hepatitis is a serious threat to the health of our people and the national economy resulted in important One of the effects of important infectious diseases.
>> How-borne
1. Hepatitis A major by fecal - oral transmission (spread of the digestive tract). By hepatitis A Patient stool contaminated water, food, etc., without being disinfected for drinking or eating very easily lead to outbreaks of hepatitis A prevalence. In recent years seafood-borne hepatitis A by the frequent occurrence of Tegillarca gross cockles, oysters,зsuch as hepatitis A virus may become portable objects.
2. The route of transmission of hepatitis B complex. transfusion transmitted: blood and blood products by the dissemination of hepatitis B virus. iatrogenic transmission: medical process from a variety of disinfection or sterilization is not without a thorough syringes, needles, etc., causing infection. due to sharing contaminated drug needles and syringes which led to the spread. mother to child transmission: acute hepatitis B and hepatitis B virus surface antigen carrying the women of childbearing age, through pregnancy and childbirth to the newborn. sexual contact: the individual with patients or carriers of hepatitis B virus to sexual contact or living in close contact could be infected.
3. Hepatitis C and hepatitis B have a similar mode of transmission. Such as drug addicts by sharing contaminated needles and syringes caused the spread of HCV. In our patients with hepatitis C was particularly prevalent in the 20th century, the 80's before the plasma of blood donors and Application has been contaminated by hepatitis C virus in plasma of people. At that time we also knew nothing about hepatitis C virus.
4. Hepatitis D virus and hepatitis B virus the same way. Because of hepatitis D virus is a virus there is no shell, it must be put on hepatitis B virus surface antigen in order to reproduce offspring in this coat, so HDV infection generally occurs at B liver virus surface antigen-positive patients and hepatitis B carriers.
5. Hepatitis E and Hepatitis A similar route of transmission. Water pollution caused by the spread of HEV is particularly prominent and popular. If the water is a one-time pollution HEV has been the subject of short-term prevalence of HEV; POLLUTION sustained if water has been the subject of HEV long-term epidemic, up to several months.
>> symptoms and hazards
1. Hepatitis A
Virus enters the human body of about 26 weeks, patients develop fever, anorexia, diarrhea, abdominal pain, joint pain and other symptoms in patients with .90% of the skin and sclera does not appear yellow dye, and because symptoms of mild, self-healing without treatment. This Yes, some people do not know he had had hepatitis A causes of infection. a small number of patients did not realize the skin yellow stained suffering from hepatitis .80% of hepatitis patients in touchliver enlargement, right upper quadrantDepartment has flu. Hepatitis A generally self-limiting disease, symptoms of a very small number of cases of heavy, deep jaundice, after active treatment can be cured.
2. Hepatitis B
Hepatitis B virus infection in the human body can be manifested as hepatitis B virus carriers, acute hepatitis, chronic hepatitis, severe hepatitis and cholestatic hepatitis.
(1) Hepatitis B virus carriers: general no symptoms, normal liver function.
(2) Acute Hepatitis B: symptoms and signs similar to those with hepatitis, but mostly not when accompanied by onset of fever, jaundice and have no jaundice, mild and severe division. Less than 1% of patients with acute onset condition after rapid increase, in the absence of timely treatment, the fatality rate reached 80% to 100%.
(3) chronic hepatitis B: the emergence of weak, easy fatigue, loss of appetite, tired and so greasy. Common signs of liver disease have face, liver palms, spider angioma, spleen and so on. Some patients to develop liver cirrhosis or cancer.
(4) severe hepatitis: hepatitis are the most heavy one type, usually liver failure, extreme fatigue, severe nausea and vomiting, jaundice rapid deepening of the liver to shrink easily to multiple medical complications such as brain dysfunction , renal failure (uremia), such as gastrointestinal bleeding, the fatality rate as high as 70%.
(5), cholestatic hepatitis: capillary cholangitis, also known as hepatitis. Usually itching skin, stool color shallow, hepatomegaly. Require extra fine B and extrahepatic obstructive jaundice phase identification.
3. Hepatitis C
Prior to the onset of hepatitis C virus enters the human body has long been about 28 weeks. The majority of patients with symptoms of mild or asymptomatic. The signs of chronic hepatitis C patients with hepatitis B, but easier than the development of hepatitis B liver cirrhosis or liver cancer.
4. Hepatitis D
Hepatitis D virus infection has three cases, the clinical symptoms are not the same.
(1) the body simultaneously infected with hepatitis B virus and hepatitis D virus, medically known as mixed infection. Its performance similar to acute hepatitis B virus infection.
(2) the body has the original hepatitis B virus infection, then infected with hepatitis D virus, medically known as superinfection.
(3) If the hepatitis B virus and hepatitis D virus in liver cells and multiply incessantly over more than half a year, known as persistent infection. D-type and hepatitis B virus infection in mixed or overlap will make the 5% 20% sick to develop into severe hepatitis.
5. Hepatitis E
Onset than the acute and acute jaundice and two types of jaundice. Sick after basic with clinical manifestations of hepatitis. With hepatitis A difference is that the HEV in the elderly suffer from infectious diseases accounted for first HEV easily develop into severe hepatitis of pregnant women, pregnant women a high fatality rate.
>> how do symptoms
Isolation and treatment of acute hepatitis should be, with particular emphasis on under the guidance of treatment at a specialist. With a good attitude, adequate rest, proper nutrition with the treatment, avoid alcohol, fatigue and liver damage drug use. Chronic hepatitis specialist guidance should be developed under the long-term treatment program, the implementation of personalized, systemic treatment.
Hepatitis A is self-limited disease, without special treatment, with physicians Spend the acute stage can be cured.
Acute hepatitis B should be immediately hospitalized. The treatment of chronic hepatitis B is a long process, there is no complete cure effects of drugs. Emphasized in the formal hospital for treatment. 612 every month to check one times, in order to detect asymptomatic abnormal liver function or cancerous. hepatocellular good hair crowd is male, 40 years old or more.
Hepatitis C treatment have much, the need for comprehensive treatment. As long as 12 years earlier insisted medication, most patients can be cured.
Acute phase of hepatitis D patients should be hospitalized; chronic HDV patients in a doctor's medication under the guidance of selection. We should be especially vigilant merger HDV chronic hepatitis B virus infection and severe hepatitis.
Hepatitis E and hepatitis A basic principle of treatment. Emphasized that the elderly, pregnant women suffering from HEV to hospitalization.
>> how to self-protection
1. Hepatitis A
Strict "start with the mouth" clearance, to develop good hygiene habits. The protection of water sources, improve water sanitation, raw vegetables and fruits should be washed, do not eat unclean food corruption, promoteֲsystem. Someone suffering from the family disease should be disinfected family will tableware for more than 10 minutes to boil. Currently, the hepatitis A vaccine has been successful, domestic and imported vaccines are available at the local Center for Disease Control and Prevention buy and injection can be effective in preventing hepatitis A infection.
2. Hepatitis B
All the body of people with hepatitis B virus (asymptomatic carriers of hepatitis B virus and hepatitis B patients) of hepatitis B virus can be transmitted to others only contagious among the crowd at the distinction between strong and weak, there is no availability of transmission sexual difference. China is a big country B is not in favor of carriers and people with chronic segregation, separation,ֲto prohibit the school, job, such as the prohibition of discriminatory conduct. good personal protection are the key to hepatitis B vaccination. At present, our country has been incorporated into the hepatitis B vaccine immunization procedures to neonatal, pre-school children as the main object. vaccinated are the most effective preventive measure.
3. Hepatitis C
Hepatitis C virus is mainly through blood-borne, so should do to stay away from drugs, in accordance with the "law of blood transfusion," the use of blood and blood products. Attention to personal hygiene, to promote the use of disposable medical items.ֲthe best food, exclusive toiletries. Husband and wife If a party has been suffering from hepatitis C, to promote sex with condoms.
4. Hepatitis D
HDV hepatitis B prevention and the same.
5. Hepatitis E
HEV hepatitis prevention basically the same, different HEV are currently no vaccines.
