Hepatitis B is a liver infectious disease that is caused by the Hepatitis B virus (HBV). This virus is a contagious virus that spread through both direct and indirect contact. Mainly viruses spread through the body&#8217;s secretion such as blood, semen, saliva, vaginal fluid and, CSF. It gives the meaning that Hepatitis B spread through close contact such as Sexual intercourse, having an unscreened transfusion.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the most important things to notice is that hepatitis B also spread during pregnancy. It is because the mother and fetus have contact with blood. It also spread with breastfeeding. So if we have to prevent the transmission of the virus, one must have to save himself from these contacts.<\/span><\/p>\n<p><b>Hepatitis B Symptoms:<\/b><\/p>\n<p><b>There are two types of symptoms in hepatitis B depends upon the severity of the disease.<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Acute hepatitis B:\u00a0<\/b><\/li>\n<\/ol>\n<p><b>Children <\/b><span style=\"font-weight: 400;\">and adults both face acute and chronic hepatitis yet there is a small difference in the symptoms of hepatitis B in children, as younger infants up to age 4-5 years have no such symptoms in\u00a0<\/span><b>acute hepatitis B<\/b><span style=\"font-weight: 400;\">. It is because the immune system is much stronger. The symptoms for acute hepatitis B usually appear after 2-3 months of exposure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Symptoms for Acute Hepatitis B are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fatigue and persistent fever<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Nausea and vomiting<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Loss of appetite<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Abdominal cramps and pain<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Frequent dark urination<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Jaundice\u00a0<\/span><\/li>\n<\/ul>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Chronic Hepatitis B:<\/b><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">In most cases of hepatitis B, chronic symptoms occur.

Doctors may advise a routine examination of your body but mainly it is diagnosed by the results shown by blood and urine test. With the advancement of medical sciences and diagnostic laboratories, viruses detection is now easier.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">At first, the doctor examines the symptoms that are visible and can be felt with bare eyes.

But chronic hepatitis needs certain types of antiviral drugs with the monetization of symptoms given by the patient of hepatitis B. these antiviral are given for certain months so that virus can be prevented. This viral load is determined by the help of PCR and after this, the doctor prescribes a special dose of antiviral drugs against hepatitis B.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sometimes, other medications against the other symptoms such as vomiting, nausea, and fever are also recommended but with the prescribed dose. Other than this doctor regularly calls his patient to have a regular checkup and recommends the patient to have PCR regularly after 2 months to check the viral load and also check liver damage.<\/span><\/p>\n<p><b>Hepatitis B Prevention:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Hepatitis B can be prevented by preventing yourself from exposure to the transmission mean of hepatitis B. Estimation says that 75% of hepatitis B is transmitted through transfusion of unscreened blood. So if you have to prevent hepatitis B you must transfuse the screened blood. So it is preferred to have known about the transmission mode of not only Hepatitis B but all types of hepatitis so the spread can be prevented.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Hepatitis B prevention relies heavily on the hepatitis B vaccine.\u00a0<\/span><a href=\"https:\/\/www.who.int\/news-room\/fact-sheets\/detail\/hepatitis-b\"><span style=\"font-weight: 400;\">According to WHO<\/span><\/a><span style=\"font-weight: 400;\">\u00a0To complete the series, all newborns receive the hepatitis B vaccine as soon as possible after delivery, preferably within 24 hours, followed by two or three doses of hepatitis B vaccine spaced at least four weeks apart. To decrease transmission from mother to kid, a timely birth dosage is a useful measure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As Hepatitis B is spread through contaminated blood so other preventions you may know are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Not share needles<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Not share shaving blades and Combs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Not using someone\u2019s things like toothbrushes, razors, towels, etc.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Use proper screening of blood and do not touch blood directly with hands.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Use gloves and masks if you are medical health professionals.
