Hepatitis A: The Dirty, Rotten, No-Good Torturer


In a world where everyone lives their lives differently from the next, you might find yourself sometimes surrounded by individuals who unbeknownst to you may have poor hygiene habits. The even scarier idea is that sometimes these kinds of people work at places where they touch and serve food. Even with protection such as gloves or head, it is still not a guarantee that what you eat outside is completely pure. 

Hepatitis A, as with other illnesses, can be spread in this manner. It is an infectious disease of the liver that though is not fatal in 95.5% of all cases, it can leave an individual with nausea, vomiting, fatigue, severe fever, dark urine, and permanent damage of the liver that can require transplant. It can be spread through contaminated food and water that contains traces of feces that contain the virus. An individual with poor hygiene is more prompt to spread it than one who has great hygiene. It has been known that the virus is most prevalent in poor hygiene regions.

In the media, we have seen this as one of the causes of Hepatitis A. In 2003, an outbreak occurred in the United States in Ohio and West Pennsylvania. More than 640 people were infected and three of the cases became fatal. Tainted green onions that were used at a restaurant in Monaca, Pennsylvania were blamed as the source and origin of the outbreak. Last month there was another outbreak that took place in 8 states as a result of contaminated frozen berries. About 118 people were infected with the virus. The berries were revealed to have come from the United States, Argentina, Chile, and Turkey. It is possible that the people who handled the berries before being transported to factories were already infected with the virus or it could have been transmitted by infected flies. Flies feed on feces and if the fecal matter is that of an infected individual, the fly can become contagious.

Could poor hygiene be the number one reason for the spread of Hepatitis A? No, but it is one of the prime reasons for the spread of the disease. Most high-income regions have low endemic levels while those that are low-income regions are known to have higher endemic levels probably in part due to lack of access to resources for combating the spread, proper sanitation, and lack of proper disposal of sewage in communities. The higher the income is in a region, the better the conditions are to afford proper healthcare, sewage disposal, and purification of water. Regions with high endemic levels have been reported to have cases where most children become infected before the age of 10. Surprisingly though, symptoms in children are not as severe as in adults and have been reported to be mild lasting between 1-3 weeks according to a report by the National Center for Biotechnology Information (NCBI). If a child recovers from infection, they can develop lifelong immunity.

Nevertheless, vaccination is highly recommended for travelers to take at least two weeks before traveling to a region where the disease is endemic. There is no specific treatment, but the vaccine can help prevent infection. At minimum, antibody responses can show within 12 days after taking a shot and at most about 4 weeks. The vaccine should not only be considered by travelers, but for people who live their day to day life as well. Outbreaks occur sometimes without warning, even here in the United States. Even after exposure to the virus, a single dose of the vaccine has protective effects even two weeks after exposure. However, manufacturers recommend two vaccine doses to increase the antibody levels for longer-term protection.
 
Millions of people worldwide have been vaccinated with no serious side-effects. The vaccine can also be given as part of regular childhood immunizations.
