<\/span>Introduction<\/strong>\u00a0<\/span><\/h2>\n\n\n\nHepatitis A is a viral disease that affects the liver 1<\/a><\/sup>. It is a significant health concern globally, including in India, where its prevalence has been reported to range between 2.1% and 52.5%2<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
Hepatitis A is caused by infection with the hepatitis A virus (HAV), which is usually spread through the faecal-oral pathway. Although common in children, with improved sanitation conditions in some parts of India, fewer kids are now getting exposed to hepatitis A at an early stage, making teens and adults more vulnerable to this infection 3<\/a><\/sup>.^{<\/sup>\u00a0\u00a0<\/p>\n\n\n\n}
Hepatitis A disease can range from a mild illness with few or no symptoms to severe cases in some. It is more commonly seen in low- and middle-income countries, such as sub-Saharan Africa, South Asia, Asia, Latin America, Eastern Europe, and the Middle East 1<\/a>,4<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
In this article, we will understand what hepatitis A is, its symptoms, transmission, management, and prevention.\u00a0<\/p>\n\n\n\n
<\/span>What is Hepatitis A?<\/strong><\/span><\/h2>\n\n\n\nHepatitis A is a viral infection that causes inflammation of the liver. Unlike other types of hepatitis (B and C), which may cause chronic disease, cirrhosis, or even hepatocellular carcinoma, hepatitis A does not lead to long-term (chronic) infections. However, hepatitis A infection can still present with mild symptoms to severe illness. In rare situations, it can even lead to acute liver failure (more likely in the elderly with underlying health conditions)4<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
It is important to note that there a change in the susceptibility trend of this infection with improving hygiene conditions across the country, affecting more of older children and adults, who often experience severe illness 3<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
<\/span>Causes of Hepatitis A<\/strong><\/span><\/h2>\n\n\n\nIs hepatitis A viral disease<\/strong>?\u00a0<\/strong>\u00a0<\/h3>\n\n\n\nYes, hepatitis A is caused by a hepatotropic virus, meaning it mainly targets the liver cells (hepatocytes). It is a small, spherical, non-enveloped virus which is roughly 27 to 32 nanometres in diameter. It contains single-stranded RNA as its genetic material, along with specialised structures that enable it to infect liver cells and replicate within them 4<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
How Hepatitis A Spreads<\/strong>\u00a0\u00a0<\/h3>\n\n\n\n
Wondering how is hepatitis A spread? Let us see!\u00a0<\/p>\n\n\n\n
Hepatitis A is mainly spread through:\u00a0<\/p>\n\n\n\n
\n
Faecal-oral route:<\/strong> The most common mode of transmission; occurs when a person consumes food contaminated with faeces (stool) from an infected individual5<\/a><\/sup>.\u00a0<\/li>\n\n\n\n
Close physical contact:<\/strong> The virus can spread through activities like oral-anal sex with an infected person or through close personal care of an infected person1<\/a>,4<\/a><\/sup>.\u00a0<\/li>\n\n\n\n
Poor hygiene during food handling: <\/strong>In households, this often happens when an infected person prepares food without proper handwashing1<\/a><\/sup>.\u00a0<\/li>\n\n\n\n
Contaminated water:<\/strong> Waterborne outbreaks (more common in areas with inadequate snatitation) can occur due to sewage-contaminated or improperly treated drinking water1<\/a><\/sup>.\u00a0<\/li>\n<\/ul>\n\n\n\n
Note: <\/strong>Everyday interactions or casual contact with an infected person usually do not transmit the virus5<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
<\/span>Signs and Symptoms of Hepatitis A<\/strong><\/span><\/h2>\n\n\n\n
Hepatitis A infection can lead to a wide spectrum of symptoms, ranging from very mild to quite severe. However, many cases (particularly among children) may have no signs and symptoms of hepatitis A.\u00a0<\/p>
