Hepatitis A is a viral infection that causes inflammation of the liver. The disease is commonly spread through contaminated food and drinking water and is seen more frequently in areas with inadequate sanitation.
Cases often increase after heavy rains and flooding because drinking water sources may become contaminated. Good hygiene and safe food practices remain the most effective ways to prevent infection.
What is hepatitis A
Hepatitis A is caused by the hepatitis A virus, which primarily affects the liver. Unlike some other forms of hepatitis, hepatitis A does not usually cause chronic liver disease.
Most people recover completely, but the illness can be more severe in older adults and individuals with pre existing liver disease.
How hepatitis A spreads
The virus spreads mainly through the fecal oral route when contaminated food or drinking water is consumed.
Poor hand hygiene, inadequate sanitation and food prepared by an infected person may contribute to the spread of the infection.
Common symptoms
Early symptoms may include fever, tiredness, nausea, vomiting, abdominal discomfort, loss of appetite and muscle aches.
As the illness progresses, some individuals develop jaundice, which causes yellow discoloration of the eyes and skin along with dark colored urine and pale stools.
Can some people have mild illness
Yes. Young children may develop very mild symptoms or may not appear ill despite carrying the infection.
Adults are more likely to develop noticeable symptoms including jaundice and prolonged fatigue.
Who is at greater risk
People living in areas with poor sanitation, those consuming contaminated food or water and individuals traveling to areas where hepatitis A is common have a higher risk of infection.
Household contacts of infected individuals may also become infected if hygiene measures are not followed carefully.
Protecting yourself and your family
Drink safe water, wash hands thoroughly before eating and after using the toilet and consume food prepared under hygienic conditions.
Wash fruits and vegetables properly and avoid consuming food or beverages from unhygienic sources, especially during the monsoon season.
Importance of vaccination
Vaccination is an effective method of preventing hepatitis A in individuals for whom it is recommended.
Healthcare professionals can advise whether vaccination is appropriate based on age, travel plans, occupation and individual risk factors.
When should medical advice be sought
Medical evaluation is recommended if jaundice, persistent vomiting, severe abdominal pain, prolonged fever or marked tiredness develops.
Prompt medical attention is also important if symptoms occur in elderly individuals, pregnant women or people with existing liver disease.
How hepatitis A is diagnosed
Healthcare professionals diagnose hepatitis A using clinical evaluation together with blood investigations that assess liver function and detect hepatitis A infection.
Early diagnosis helps guide appropriate care and reduces the risk of spreading the infection to others.
Healthy habits protect the liver
Maintaining good personal hygiene, using safe drinking water and following proper food safety practices remain the most effective ways to reduce the risk of hepatitis A.
Public awareness and early medical evaluation are essential for limiting outbreaks and protecting community health.
