World Hepatitis Day: Current Affairs
World Hepatitis Day
Relevance: Science and technology.
Context: World Hepatitis Day was commemorated to increase the awareness of viral hepatitis.
- Hepatitis is an inflammation of the liver that can cause a series of health problems often leading to death.
- The theme of World Hepatitis Day 2020 is “Hepatitis can’t wait”, conveying the urgency of efforts needed to eliminate hepatitis as a public health threat by 2030.
- It disturbs various metabolic processes such as bile production, excretion, fat and protein metabolism, activation of enzymes, and synthesis of proteins.
- It’s commonly caused by a viral infection, but there are other possible causes of hepatitis.
- Usually caused by a group of viruses known as the “hepatotropic” (liver-directed) viruses, including A, B, C, D, and E viruses.
- Other viruses may also cause it, such as the varicella virus that causes chickenpox. SARS-CoV-2, the virus causing Covid-19 may injure the liver, too.
- Other causes include drug and alcohol abuse, fat buildup in the liver (fatty liver hepatitis), or autoimmune hepatitis.
Types of Viral Hepatitis:
- Hepatitis A is always an acute, short-term disease, while hepatitis B, C, and D are most likely to become ongoing and chronic..
- Hepatitis E is usually acute but can be particularly dangerous in pregnant women.
|Hepatitis A||Hepatitis B||Hepatitis C||Hepatitis D||Hepatitis E|
|It is acute, and in the majority of cases, symptoms in young people are not recognized.|
|It is spread by flattened wounds, contact with blood, saliva, and infectious body fluids.|
|Transmitted through infected needles, at the time of birth, through an infected person’s body fluids, and Sexually.||Severe liver diseases are caused by the virus Hepatitis D (HDV). It spreads from infected blood or wound. Sometimes it might occur with Hepatitis B.||Hepatitis E is a waterborne disease caused by the hepatitis E virus (HEV). It might be circulated through food, water, and contaminated blood.|
|Vomiting, nausea, fever, severe abdominal pain, jaundice, and weakness are some of the symptoms.||Abdominal pain, fatigue, and jaundice are all symptoms of hepatitis B. Symptoms do not manifest themselves for one to six months.|
|Loss of appetite, tiredness, frequent fever, yellowing of the skin or eyes, joint pain, abnormalities in urine.||Hepatitis D is a rare form of hepatitis that only occurs in conjunction with hepatitis B infection. The hepatitis D virus can’t multiply without the presence of hepatitis B.||Hepatitis E is mainly found in areas with poor sanitation and typically results from ingesting fecal matter that contaminates the water supply. It could be either acute or chronic.|
|The hepatitis A vaccine aids in disease prevention.||Hepatitis B Vaccine could be done for both adults and children.||It cannot be transmitted through food or water.No vaccine.||No vaccine.||For Hepatitis E, a promising vaccine is in the works.|
