Hepatitis B is a liver disease due to the hepatitis B virus ( HBV ) . The hepatitis B virus was the first hepatitis computer virus to be identified . It is a disease that strike 300 million masses in the world and is estimated to be responsible for between 250,000 and 500,000 deaths per year . The prevalence of infection with the hepatitis B virus vary greatly in different part of the world . The in high spirits rates of transmission are found in Southeast Asia , China , and southerly Africa .
Most people who acquire the hepatitis B computer virus recover without consequence . This form of infection , which lasts less than 6 months , is known as acute hepatitis B. On the contrary , when the infection hold out for more than 6 months , it is hump as chronic hepatitis B. Approximately 5 % of adults who grow the infection modernise the inveterate form . The likeliness of develop continuing hepatitis B depends on the age and immune status ( defenses ) of the affected role , being higher when acquired in puerility than when acquire as an grownup .
The clinical manifestations of hepatitis B computer virus contagion are very wide-ranging , and it is significant to emphasize that frequently this infection may not give any symptoms for many years , which does not inevitably think that the contagion is ensure . The damage that the hepatitis B virus make in the liver is also varying and bet on the ability of the liver to rectify itself and the physical structure ’s power to control the infection . The most of import consequences of this transmission in the long terminal figure are the evolution ofliver cirrhosisand hepatocellular carcinoma .
In the last time a series of novel alternatives for the treatment of the disease have been develop . On the other hand , there is a highly in effect and dependable vaccine to prevent transmission .
Symptoms of Hepatitis B
Acute Hepatitis B:
symptom of acute hepatitis B fall out 1 to 4 months after computer virus acquisition . Many people may not have any symptom . Symptoms include : Fatigue , decreased appetite ( anorexia),nausea , jaundiceor yellowing of the peel , coluria , pain in the upper right orbit of the venter , pain or inflammation of the joints . These symptoms unremarkably disappear within 3 month .
A very low proportion of people with acute hepatitis B ( 0.1 to 0.5 % ) develop a more terrible shape of the disease characterized by liver failure ( fulminant hepatitis ) .
Chronic Hepatitis B:
inveterate hepatitis B is often symptomless or is manifest only by nonspecific symptom such as fatigue or lessen appetite . at times there are aggravation of the rabble-rousing activity of the liver that can result in aggravation of the symptom . To the extent that the contagion cause gravid damage to the liver , symptom of liver cirrhosis may manifest . 10 to 20 % of affected role may have excess - hepatic manifestations of the disease , most oft vasculitis and glomerulonephritis .
Can Hepatitis B Go Away Completely?
Acute hepatitis B does not require specific discussion , since 95 % of adults recover spontaneously . It is important to remember that touch of the somebody with acute hepatitis B should be evaluated and eventually vaccinated . Acute hepatitis B is extremely contagious , so measures should be taken to foreclose its transmission .
People who develop continuing hepatitis B should be evaluated by a doctor experienced in the management of this disease ( gastroenterologist or hepatologist ) . Treatment conclusion are individualized . The aim of the treatment is to keep the retort of the virus under control to avoid the progressive damage of the liver .
Prognosis of Hepatitis B
The evolution of the disease is quite variable . There are probably genetic factors that are relate with the different power to keep viral retort under ascendency . The order of magnitude of the damage is also associate with age ( often children have heavy viral riposte with little liver damage ) , sex ( usually the disease progresses quicker in men than women ) , alcoholic drink use and the mien of other virus such as hepatitis C and five hundred computer virus .
It is important to know that you’re able to spread the computer virus to others , even if you do not find fed up .
