Hepatitis B






 Hepatitis B


Of all the viruses that ravaged humanity throughout history, after AIDS, hepatitis stands because of the most annoying and gruesome virus. It derives its lethality from its ability to start out asymptomatic and switch chronic over the years. Hepatitis may be a family of viruses that affects the liver resulting in cancer of the liver in late stages, making it life-threatening. Hepatitis infections are often both acute and chronic. hepatitis B may be a virus of the hepatitis family that affects the liver, resulting in cancer over an extended time. consistent with WHO, the transmission rates of HBV haven't been reduced since the no vaccination era of the 2000s.


Symptoms:


Many cases are asymptomatic when newly suffering from HBV. Some people may develop an easy illness with subsequent symptoms.


Jaundice, where the eyes and skin turn yellow

Dark urine

Extreme fatigue

Nausea

Vomiting and pain around the liver area

Small chance of liver failure resulting in death

Transmission:


The most common and prominent ways of transmission, causing the disease in uninfected people are mentioned below.


Infected mother to the kid remains the foremost common way of transmitting the virus (perinatal transmission).

Exposure to the blood of patients is that the next commonest way of transmission in children

Needlestick injury

Tattooing

Piercing of the ears

Exposure to body fluids like vaginal, menstrual, saliva, and seminal fluids

Sexual transmission in homo sex is more very highly prevalent alongside people having sex with multiple partners and sex workers

Incubation period:


The virus features a survivability period of seven days. The virus stays active during this era and may infect those that are available in contact with it. it's a mean incubation time of 75 days, starting from 30 to 180 days. It is often detected within 30 to 60 days of the primary infection.


Diagnosis:


It is clinically impossible to differentiate hepatitis B from other hepatitis family viruses. you've got to urge a laboratory inspection of the blood sample. Several blood tests are often done to differentiate the chronic and acute stages of the hepatitis B virus. The blood sample is tested for the presence of the HBsAg surface antigen of hepatitis B. Acute infections reveal the presence of the HBsAg and therefore the antibody to an antigen, HBcAg. The presence of HBeAg indicates the multiplicity rate by the virus within the body. an individual with high levels of HBeAg is very infectious. The presence of HBsAg antigen for quite six months indicates that the disease is chronic. HBsAg antigen is the prime explanation for cancer of the liver.


Treatment:


Acute infections aren't treated. Acute infections are cured by taking proper nutrition and care. Unnecessary medication like Acetaminophen and paracetamol for vomiting should be avoided. they have to require more fluids to exchange the lost fluids.


Hepatitis B medicines for the chronic stage are oral antiviral medication like tenofovir and entecavir. they're common side effect drugs that you simply can consume one pill each day. They require less monitoring due to fewer side effects Treatment can improve anticipation and therefore the risk of developing cirrhosis. hepatitis B is often prevented by vaccination, which is safe, available, and effective
