Prevalence Of Hepatitis Virus Infection Among Pregnant Women


Abstract


In this project a comprehensive analysis or discussion of the result is made. It gives a detailed analysis of the result of investigation done. The blood sample of 200 (two hundred ) patient of the hospital that is national Orthopedic Hospital Enugu were tested. Of the tese, about 110 patients tested positive to Hepatitis B virus. The test done was a routine test in which HBsAg was screened for in the blood sampling the patients. This is usually the test done in screening for HBV in patients in Orthopedic Hospital Enugu as the reag into were always readity available . for easy collection and analysis of dfata the patients were studied under five (5) variable age, Donicile occupation and education. The last variable education was not studies as it was not possible to obtain a comprehensive analysis of the educational status of the patent. For age, the patients were grouped into seven (7) different age groups between 1 to 70 years with 10 yeard interval between each age group that is 1-10, 11-20 and so on. Infection was highest amongst young women within 21-30 age group. Tyhius accounted for 37.5% of the 200 population and 17.5% of the 110 infected population. It was lowest amongst two age group 1-10 and 60-7-0 as they both made up 2.5% apiece of the infected population. This is seenin.

Introduction

1.1 Background to the Study

Hepatitis is an inflammation of the liver characterized by the presence of inflammatory cells in the tissue of the organ (Ryder & Beckingham, 2001). It may occur with limited or no symptoms, but often leads to jaundice, anorexia (poor appetite) and malaise. Hepatitis is acute when it lasts less than six months and chronic when it persist longer. A group of viruses known as the hepatitis viruses cause most cases of hepatitis worldwide, but it can also be due to toxins (notably alcohol, certain medications and plants), other infections and autoimmune diseases.

The hepatitis virus is found in the blood and other body fluids and is transmitted from person to person, the most common routes of infection includes blood transfusions and blood products where there is no screening for blood-borne viruses, medical or dental interventions in countries where equipment is not adequately sterilized mother to infant during childbirth, sexual transmission (in the case of hepatitis B), sharing equipment for injecting drugs, sharing straws, notes etc. for snorting cocaine (cocaine is particularly alkaline and corrosive), sharing razors, toothbrushes or other household articles, tattooing and body piercing if done using unsterile equipment (Ahmedin et al, 2004).

The hepatitis B virus is spread between people through contact with the blood or other body fluids (i.e. semen, vaginal fluid and saliva) of an infected person, while the hepatitis C virus is spread through direct contact with infected blood. Very rarely it can also be passed on through other body fluids (Redmond, 2007). Many people infected with hepatitis B or C rarely displays any symptom, although they can still transmit the virus to others.

Hepatitis B is a major disease of serious global public health proportion. It is preventable with safe and effective vaccines that have been available since 1982. Of the 2 billion people who have been infected with the hepatitis B virus (HBV) globally, more than 350 million have chronic (lifelong) infections. Over 20 million people are infected annually with this virus (Mohammed et al, 2003). Hepatitis C is a viral infection of the liver and is the most common blood-borne (direct contact with human blood) infection. The major causes of HCV infection worldwide are use of unscreened blood transfusions, and re-use of needles and syringes that have not been adequately sterilized. The world health organization (WHO) estimates that about 3% of the world populations (200 million people) have so far been infected with the Hepatitis C virus. Almost 50% of all cases become chronic carriers and are at risk of liver cirrhosis and liver cancer (Ahmad, 1998).

Viral hepatitis during pregnancy is associated with high risk of maternal complications. There is a high rate of vertical transmission causing fetal and neonatal hepatitis which can have serious effects on the neonate, leading to impaired mental and physical health later in life. A leading cause in maternal mortality is also said to be the most familiar cause of jaundice in pregnancy. Peri-natal transmission of this disease occurs if the mother has had acute Hepatitis B infection during late pregnancy, in the first postpartum or if the mother is a chronic HBsAg carrier. Hepatitis C transmission occurs predominantly around time of delivery and pregnancy. Using this background information, the epidemiology of viral hepatitis during pregnancy is essential for health planners and program managers. Thus, the current study aimed at investigating the prevalence and the possible predisposing factors for Hepatitis B and C viruses among pregnant women using the University of Benin Teaching Hospital as a case study.


1.2 Statement of the Problem

Viral hepatitis during pregnancy is associated with high risk of maternal complications and has become a leading cause of foetal death. Hepatitis one of the major and common infectious diseases of the liver world wide is caused by a small enveloped DNA virus, the hepatitis B virus (HBV). Nigeria is classified among the group of countries endemic for HBV infection. Currently about 18 million Nigerians are infected. Many of these people may not be aware of the infection and hence fail to seek appropriate medical attention therefore progressing to chronic liver disease, cirrhosis and hepatocellular carcinoma. Similarly when pregnant women are involved they constitute a serious health risk not only to their unborn child but also the society at large.


1.3 Objectives of the Study

The following are the objectives of this study:

  1. To provide an overview on hepatitis virus infection.
  2. To examine the prevalence of hepatitis virus infection among pregnant women.
  3. To identify the consequences of hepatitis virus infection on pregnant women.

1.4 Research Questions

  1. What is hepatitis virus infection?
  2. What is the prevalence of hepatitis virus infection among pregnant women?
  3. What is the consequences of hepatitis virus infection on pregnant women?

1.6 Significance of the Study

The following are the significance of this study:

  1. The results from this study will educate the general public especially the pregnant women on the prevalence and prognosis of hepatitis virus infection of pregnant women.
  2. This research will be a contribution to the body of literature in the area of the effect of personality trait on student’s academic performance, thereby constituting the empirical literature for future research in the subject area.

1.7 Scope / Limitations of the Study

This study will cover the prevalence of hepatitis virus infection with special focus on hepatitis B and C.


1.8 Limitation of Study

Financial constraint

Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet, questionnaire and interview).

Time constraint

The researcher will simultaneously engage in this study with other academic work. This consequently will cut down on the time devoted for the research work.

Conclusion and Recommendation

5.1 Conclusion

After the investigations, collection and analysis of data, in which 200 patients’ blood samples were tested, 110 patients tested positive to the virus, and only 90 patients were negative.

These 110 patients included five un-married women, twenty students, forty unskilled workers, twenty semi skilled workers, and finally twenty-five professionals.

The above data went a long way to prove the hypothesis “Hepatitis B is prevalent among patients in Orthopedic Hospital Enugu” to be true. This is seen in the fact that more than half of the patients tested were positive.

Therefore, it is hereby concluded that the infection, Hepatitis B (Australian antigen) is prevalent among patients in the said hospital; undoubtedly as the data speaks for itself.


5.2 Recommendation

One cannot prevent a virulent organism such as the Hepatitis B virus without being extremely careful. It is, therefore, recommended that people who are at risk of contacting this virus should endeavor to take the vaccine against this virus in order to build up antibodies against the antigen. Also, when one is exposed to the virus, the vaccine should be given without 48hours of exposure and not 7days like most textbooks recommended.

Furthermore, contact with all body fluids infected with HBV, and equipment contaminated with infected body fluids should be avoided. Unprotected sex should be avoided, and also not encouraged, while the use of unstorile sharp instruments should be avoided inorder to prevent and control the transmission of Hepatitis B virus.
