Hepatitis A Report: Analysis of Epidemiology and Prevention

This report focuses on Hepatitis A, a highly infectious liver disease, and its impact on public health. It discusses the disease's symptoms, causes, and prevalence, highlighting a decline in cases in Australia from 2003 to 2016. The report emphasizes the importance of herd immunity, particularly for unvaccinated individuals, in preventing the spread of the disease. It stresses the significance of a strong immune system through vaccination to protect communities from various infectious diseases, including measles, influenza, and cholera. The report references specific studies and data to support its analysis, underscoring the need for continued vaccination efforts to maintain community health and well-being.

INTRODUCTION
Hepatitis A is highly liver infectious disease which impact on functioning of liver. There are
many symptoms of it such as loss of appetite, dark urine, intense itching, etc. Hepatitis A is
caused by virus which infect liver cells and inflammation (Foster and et.al., 2019). Besides,
drinking contaminated water, close contact with person who is infected, etc. are causes as well.
In Australia there is decline in rate of Hepatitis A from 1.8 per 100,000 in 2003- 05 to 1.1 per
100,000 in 2006- 07. Also, it is found that only 145 notification was observed in 2016. Besides,
74 were hospital in 2016. However, between 1997- 2016 only 35 death were observed. In
addition, between 1996- 2005 average of 10% of hospitalisation people were found to be
indigenous Australians. Thus, Hepatitis A has highly impacted on indigenous and Torres and
Aboriginal community of Australia.
There is great importance of herb immunity in prevention of herd immunity. It is because it
helps in preventing community that is no vaccinated against infectious disease (Peak and et.al.,
2020). Basically, children and adult who are not vaccinated needs to have herd immunity. This
helps in preventing against VPD in Australia. It is important to maintain high immunity as it
makes immune system strong. So, entire community is prevented from VPD. Also, immune
system helps in preventing from other infectious NPD as well such as measles, influenza,
cholera, etc. Furthermore, it helps in health and wellbeing of our communities with vaccines
eradicating some illnesses altogether.
