what is the most common factor involved in spreading hepatitis a?
439595
Transmission. The hepatitis A virus is transmitted primarily by the faecal-oral route; that is when an uninfected person ingests food or water that has been contaminated with the faeces of an infected person.

Transmission. The hepatitis A virus is transmitted primarily by the faecal-oral route; that is when an uninfected person ingests food or water that has been contaminated with the faeces of an infected person. In families, this may happen though dirty hands when an infected person prepares food for family members.
1340749
Adults at increased risk for hepatitis A. Adults who are at risk for hepatitis A can also get vaccinated. The shot is given in 2 doses — adults get each dose 6 to 18 months apart.
694777
Symptoms. The incubation period of hepatitis A is usually 14–28 days. Symptoms of hepatitis A range from mild to severe, and can include fever, malaise, loss of appetite, diarrhea, nausea, abdominal discomfort, dark-coloured urine and jaundice (a yellowing of the skin and whites of the eyes).

Hepatitis A is caused by a virus that infects liver cells and causes inflammation. The inflammation can affect how your liver works and cause other signs and symptoms of hepatitis A. The virus most commonly spreads when you eat or drink something contaminated with fecal matter, even just tiny amounts.

The hepatitis e antigen, or HBeAg, is a marker of an actively replicating HBV virus infection. Those with a positive HBeAg have active replication in their liver cells, more of the virus circulating in their blood, and as a result, they are more infectious, with a higher likelihood of transmitting HBV to others.
768565
This can happen when an infected person does not adequately wash their hands after using the bathroom then touches other things such as food. When other people eat that food, they can get infected with hepatitis A. Usually the transmission is between people in very close personal contact.
157185
Person-to-person contact Hepatitis A can be spread from close, personal contact with an infected person, such as through having sex, caring for someone who is ill, or using drugs with others. Hepatitis A is very contagious, and people can even spread the virus before they feel sick.
262968
Hepatitis C is usually spread when blood from a person infected with the hepatitis C virus enters the body of someone who is not infected. Today, most people become infected with the hepatitis C virus by sharing needles or other equipment to prepare or inject drugs.
26461
There are several types of viral hepatitis, known as A, B, C, D and E. Hepatitis D is linked to hepatitis B and is not considered as a separate type of its own any longer. Hepatitis A and E are spread by faecal contamination and are rarely considered blood borne pathogens.

The transmission of hepatitis A is mainly faeco-oral, and the infection control measures those called "Enteric Precautions", or blood and body fluid precautions. These include the wearing of latex gloves when handling faeces, urine, saliva, and blood. Handwashing is essential.

Hepatitis can be caused by many things such as a physical injury, bacterial infections, adverse drug interactions, and viruses. There are currently 5 viruses identified (hepatitis A, B, C, D and E) that specifically attack the liver and cause “viral hepatitis” or inflammation of the liver due to a virus.
926992
The hepatitis A vaccine does not cause hepatitis because it does not contain the live virus. It contains inactivated hepatitis A virus. The vaccine works by stimulating the body to produce antibodies, which are proteins that will fight and kill the virus and prevent hepatitis A infection.
235143
A different virus is responsible for each type of virally transmitted 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.

You can get it through contact with the blood or body fluids of an infected person. In the U.S., it's most often spread through unprotected sex. It's also possible to get hepatitis B by sharing an infected person's needles, razors, or toothbrush. And an infected mother can pass the virus to her baby during childbirth.

Hepatitis A (Hep A) is liver inflammation caused by the hepatitis A virus. Hepatitis A is very contagious. This means that you can easily catch the virus from someone or give it to another person.
1450836
You can also get it if you share contaminated needles and syringes. Hepatitis A can be prevented by being careful where you eat and drink; practising safer sex, including using male and female condoms, dental dams and latex gloves; never sharing needles and syringes; and/or having a hepatitis A vaccination.
