Members of the Hepadnaviridae Family:

HEPADNAVIRIDAE family lineage

Orthohepadnavirus (mammals) genus

DHBV - Duck Hepatitis Virus (Ducks and Geese)

HHBV - Heron Hepatitis B virus

Others: Ross' Goose Hepatitis B virus, snow goose hepatitis B virus, and stork hepatitis B virus

Avihepadnavirus (avian) genus

HBV - Hepatitis B Virus (Humans and Chimps)

WHV - Woodchuck Hepatitis Virus (Woodchucks)

GSHV - Ground Squirrel Hepatitis Virus (Squirrels, woodchucks, chipmunks)

WMHV - Wooly Monkey Virus (Wooly Monkey)

Others: Old World and New World primate viruses

WHV and GSHV both are morphologically the same as HBV and have about 60% of the same sequence as HBV. HBV only grows in humans and chimps, but not baboons or lower animal species.

Clinical Manifestations: How do you know you have Hepatitis B?

30% of infected individuals do NOT have symptoms. Those who do present with jaundice, fatigue, abdominal pain, loss of appetite, nausea, vomitting, and joint pain. Fever can be absent or mild. After infection, the incubation period between exposure and first symptoms is 45-120 days, averaging around 60-90 days. This period is affected by the amount of virus in the inoculum, mode of transmission, and factors relating to the host. Primary infection is usually associated with little or no liver disease and mild to fulminant hepatitis.

The next phase of disease, icteric phase, usually occurs 10 days after symptoms begin. Dark urine followed by pale stools, yellowish coloring in the mucous membranes, conjunctivae, sclerae (whites of eyes), and skin then appear. Clinically, Jaundice is indicated by bilirubin levels of 20-40mg/L. It is accompanied by hepatomegaly and splenomegaly.

The infection usually resolves after 4-8 weeks. Most patients recover with few consequences and without recurrence in the future. Young children rarely are affected and develop disease; however those that are are at a high risk of becoming chronic carriers, especially if they are under the age of 7.

The hallmark of acute Hep B infection is a large increase in serum transaminase (aminotransferase) activity.
Epidemiology: Where is Hepatitis B found?

There are 350 million carriers of Hepatitis B worldwide and most of them are concentrated in developing countries. Hepatitis B is a disease of the poor. Sub-Saharan Africa, most of Asia, and the Pacific are hit hardest. The Amazon, southern parts of Eastern Europe, and Central Europe are also affected. In Western Europe and the United States, the prevalence is only 1%. It is estimated that there are 1.2 million carriers in the United States. Most of these individuals are infected during childhood and up to 10% of them become chronically infected. In these regions, liver cancer is one of the top 3 killers of adult males.

estimated that about 4 million people

It is estimated that about 4 million people in the United States are infected with hepatitis C, which is about 2% of the population. This makes hepatitis C much more common than HIV infection. There is an estimated 200 million people infected with HCV world wide.

And then there is Hepatitis B, a more readily transmitted virus which is rapidly becoming an monumental epidemic. Some facts bout Hepatitis B:

* 2 billion people have been infected with HCB (1 out of 3 people).
* 400 million people are chronically infected.
* 10-30 million will become infected each year.
* An estimated 1 million people die each year from hepatitis B and its complications.
* Approximately 2 people die each minute from hepatitis B.

Hepatitis C and B have been compared to a “viral time bomb”.

Apparently on the 19th May 2009 a few days prior the exact Jupiter Chiron Neptune conjunction the countries of the world celebrate “World Hepatitis Day”. Lets hope that the news is good and that the World Health Organisation announces research advancements in the fight against our many diseases and viral threats. God forbid that Swine Flu has any chance of advancing in the world.

The three major planetary bodies of Chiron, Jupiter and Neptune are highlighting the nature of our Global health. The conjunction is operating in “unseeable” or collective frameworks. One could say that our world is not in good shape presently. The stress from our global financial recession, our environmental issues and the threats of disease are major underlying themes that we cannot ignore in our lives. The question is how will we help reduce the stress in the face of our current realities? Society has tended to use drugs and alcohol and even take spiritual avenues to quell the stresses of too much reality. I cant see those options changing in the near future.

Chiron, Jupiter and Neptune are co joining to highlight our global health predicaments. The Cosmos usually throws something at us so that we sit up and take notice.

Our World is in a state of ill-health it seems – hopefully the Doctor is on his way?
