Transmission
Hepatitis B is a bloodborne viral infection that causes chronic disease of the liver. It can be transmitted from person to person via contact with contaminated blood and bodily fluids, although a major mode of transmission is via sexual contact. Transmission from an infected man to a woman is three times more effective than from an infected woman to a man. Anal intercourse, both insertive and receptive, is thought to be associated with an increased risk of transmission.
Hepatitis B can also be transmitted from mother to baby, via unsterilised needles, such as drug users sharing needles, or via contaminated blood products. |
|
 |
Incubation
The average incubation period is between 45 and 180 days, and usually between 60 and 90 days. |
|
 |
Illness
Not everyone with hepatitis B will show any symptoms. Those suffering from symptoms generally show flu-like symptoms including loss of appetite, sore throat, tiredness and joint pains. Others with acute hepatitis can develop general abdominal discomfort, nausea and vomiting, a rash and jaundice. |
|
 |
Treatment
There is no specific treatment available for acute hepatitis B. Patients are encouraged to rest, drink plenty of fluids, have a healthy diet and avoid alcohol and certain prescribed drugs.
Patients with chronic hepatitis B can be treated with alpha interferon, or other drugs with antiviral properties such as lamivudine. Treatment should be based on an individual basis, as not all patients are suitable for treatment.

 |
Exclusion
This is only necessary if the patient is unwell or bleeding. |
|
 |
Notification
Hepatitis B is a notifiable disease. Any positive results for hepatitis B should be reported to the Local Authority Proper Officers under the Public Health (Infectious Diseases) Regulations 1988. Please refer to your local policy document for further information. |
|
 |
Complications
If the individual is still carrying the virus after six months they can develop chronic hepatitis B, and this is common among people with immunodeficiency. Chronic carriers may have no symptoms and may be unaware that they are infectious. They have a high risk of transmitting the disease and developing cirrhosis of the liver and primary liver cancer. |

Prevention
A vaccination is available to travellers or those at risk of contracting the virus. In order to help prevent catching the virus in the first place, safe sex should be practised at all times and a condom used regularly and carefully. It should be ensured that any needles used for tattoos or any kind of drug use are adequately sterilised and needles should never be shared.
In order to help prevent spread of the disease, inoculation with the vaccine is recommended in the following groups:
- babies born to infected mothers
- parenteral drug misusers
- people who change sexual partners frequently
- homosexual or bisexual males
- male or female prostitutes
- close family members of a carrier
- haemophiliacs
- people who work in close proximity caring for others – such as prison guards, healthcare workers, care givers
- people from endemic countries.
If the healthcare worker becomes exposed to the hepatitis B virus during an occupational procedure they should follow the exposure guidelines and seek advice immediately. Certain procedures must be carried out straight away in order to maximise their effectiveness.
The site of injury should be immediately washed and cleaned. The exact method of cleansing depends upon the type of injury and the area of the body involved:
- percutanous exposure – encourage the wound to bleed and wash with soap and water
- cutaneous contamination – wash with soap and water
- mucous membrane contamination – flush thoroughly with water
- contamination of the eyes – irrigate with clean water, saline or sterile irrigants.
Following exposure to hepatitis B infection, through an occupational incident, then a full risk assessment should be carried out. This includes taking and storing a sample of serum and plasma from the healthcare worker at the time of the incident (or baseline). The potential for transmission should be assessed based on the type of exposure and body material involved. Consent should be sort from the patient involved to test for Hepatitis B. If consent is not obtained then the patient should be considered as being infectious.

Vaccine
An effective vaccine is available to protect against hepatitis B. Hepatitis B is the only sexually transmitted disease that can be prevented by a vaccine. The vaccine produces an immune response within the body giving immunity against the disease. There is also a specific immunoglobulin available which produces a passive response. This gives an immediate but temporary immunity against the virus and can be used in cases where accidental inoculation or contamination has occurred.
The vaccine is given in three doses over a six-month period. In GUM clinics this is given over one month at nought, one and three-week intervals. An accelerated vaccine is available for travellers. In general, the vaccine is very well tolerated and has few side-effects.
All healthcare workers should be vaccinated against hepatitis B, following the standard vaccination schedule. It is recommended that all individuals are vaccinated, or tested for immunity, against hepatitis B before they enter nursing or medical schools, or before they begin employment within the healthcare environment.

NHS Quality Improvement Scotland (QIS) was set up as a special health board by the Scottish Parliament in 2003. Its role was to improve the quality of care and treatment delivered by NHS Scotland. As part of its role, NHS QIS investigated the sexual health services within Scotland and recommended how they can best support and improve the services offered around sexual health.
From their investigation, the group came up with five key clinical indicators (KCI) which would be used to monitor the improvement in sexual health care. Hepatitis vaccine uptake of men who have sex with men is one of the KCI set out for 2006.

Contraindications
Immunisation with the vaccine should not be given to patients suffering from a sudden feverish illness. It is important that all serious adverse effects be reported via the yellow card system. |
