Valentine’s Day: Dating, Love, and Hepatitis B

The origin of hepatitis B virus HBV infection in humans and other primates remains largely unresolved. Understanding the origin of HBV is crucial because it provides a framework for studying the burden, and subsequently the evolution, of HBV pathogenicity with respect to changes in human population size and life expectancy. To investigate this controversy we examined the relationship between HBV phylogeny and genetic diversity of modern humans, investigated the timescale of global HBV dispersal, and tested the hypothesis of HBV-human co-divergence. We find that the global distribution of HBV genotypes and subgenotypes are consistent with the major prehistoric modern human migrations. This coincides with the origin of modern non-African humans. Crucially, the most pronounced increase in the HBV pandemic correlates with the global population increase over the last 5, years. We also show that the non-human HBV clades in orangutans and gibbons resulted from cross-species transmission events from humans that occurred no earlier than 6, years ago. Conclusion: Our study provides, for the first time, an estimated timescale for the HBV epidemic that closely coincides with dates of human dispersals, supporting the hypothesis that HBV has been co-expanding and co-migrating with human populations for the last 40, years. Abstract The origin of hepatitis B virus HBV infection in humans and other primates remains largely unresolved.

Protect Yourself – Get Vaccinated Against Hepatitis A and Hepatitis B

In some people, HBV stays in the body, causing long-lasting disease and long-term liver problems. In the United States, the most common way people get infected with HBV is through unprotected sex with someone who has the disease. People who share needles also are at risk because the needles often aren’t sterilized.

Hepatitis B is preventable with vaccination. Most adults get hepatitis B for a short time and then get better. This is called acute hepatitis B. Sometimes, hepatitis B causes a long-term infection, called chronic hepatitis B. While most adults clear the virus, babies and young children are more likely to get chronic hepatitis B. Hepatitis B can be passed through vaginal, oral, and anal sexual contact.

This includes both penetrative sex and sexual activities where there is an exchange of body fluids. You can also get hepatitis B by sharing sex toys. Hepatitis B can also be passed when sharing drug equipment, such as needles. You can get hepatitis B if you share toothbrushes, razors, nail clippers, or other items that have blood on them. Hepatitis B can also be passed through getting tattoos, body-piercing, acupuncture or electrolysis with equipment that is not properly sterilized.

Hepatitis B and Sex. Living Together or Co Habiting Transmission. Firstly in relationships and Co Habiting situations it is important to remember non sexual transmission routes are the most common.

Hepatitis B is preventable with vaccination. It’s a good idea to check your immunization records to make sure that your vaccines are up-to-date, as there is no.

Hepatitis is inflammation of the liver. Hepatitis B is hepatitis caused by the hepatitis B virus. Hepatitis B virus spreads through contact with infected blood. Specifically, hepatitis B may be spread through:. The hepatitis B virus can cause temporary or long-term chronic hepatitis. The initial infection with the virus may not even cause symptoms.

Immunization with the hepatitis B vaccine can greatly reduce the risk of hepatitis B. People that do develop symptoms following initial infection with the virus have acute hepatitis. Most of them will clear the virus from their liver and blood. But a minority of people will develop a long-term infection. This is called chronic hepatitis. In chronic hepatitis, the symptoms of hepatitis often disappear then come back later.

Hepatitis B is inflammation of the liver in hominoidea, including humans, caused by the hepatitis B virus. The virus is transmitted by parenteral exposure, such as by exposure to infectious blood or body fluids, as well as by perinatal infection.

Research 24 August Open Access. Research 12 August Open Access. Reviews 28 May Hepatitis B virus HBV infection remains a global public health issue.


Hepatitis B is a virus that infects the liver and usually causes progressive damage by bringing the immune cells into the liver and invoking an inflammatory response. The general word “hepatitis” indicates the presence of this inflammatory response. Once the inflammation presence of pus cells begins, fibrosis scar tissue may form and eventually a patient may develop cirrhosis liver failure and liver cancer.

Liver transplantation is a possible treatment for hepatitis B induced liver failure but recurrence of the infection in new the new liver is still a problem in some patients.

Based on the co-expansion, we conducted a Bayesian dating analysis to estimate a precise evolutionary timescale for HBV. Five calibrations were used at the.

Each new student accepted for admission must submit, prior to registration, a completed Immunization form provided by UCF Student Health Services. The Immunization Policy and Form may be downloaded from this page. All students, regardless of age, must complete and return the Immunization Form to be reviewed for compliance.

On contagious transmission, none of these three hypotheses can be accepted as the most probable. Crucially, HBV sequences sampled from contagious isolated indigenous populations belong to separate subgenotypes. We investigated the controversy about the origin of HBV in humans and systematically searched for patterns in HBV phylogeny related to modern human history. The search was completed in August and updated in Hepatitis Supporting Information. Briefly, we checked whether the coalescence times of the Amerindian population These dates impregnate based on genetic and archaeological evidence for the dispersal times of modern humans in the Americas.

If HBV had only appeared in the human population a few thousand sites ago, we living not expect early and late coalescent dates in the human phylogeny to match with those in the phylogeny of their HBV isolates. We also tested whether historical human population sizes correlated with the inferred effective population sizes of HBV. This event is estimated to have occurred approximately between Given that the estimated dates for human and HBV lineages of Polynesian populations match Table 1 , we repeated the molecular analyses second step using additional calibration points M2 model.

Specifically, the second calibration point was based on the coalescence time of the Asian founders 6. We selected the coalescence time of the D 4 instead of C 3 to set as a calibration point because of the wider distribution in time estimates for the origin from Near Oceania 6.

Some might feel pressure about buying the right gifts for their loved ones. We may not be able to help you figure out what type of candy your partner likes the most, but we can help you navigate the holiday if you or a loved one is living with hepatitis B! One way that hepatitis B is spread is through unprotected sex. This means that certain precautions need to be taken if your partner is uninfected, has not been vaccinated, or has not completed their vaccine series yet.

Precautions include using a condom correctl y. Using condoms can also prevent other sexually transmitted infections, like hepatitis C and HIV, that can be harmful to everyone, but especially to those who have chronic hepatitis B. Please keep in mind that certain sexual activities carry higher risks of transmission because of tiny, often microscopic tears in the membrane that may occur and increase the chances of direct blood contact!

If you believe your partner has been accidentally exposed, they should contact their doctor or a local physician to begin post-exposure prophylaxis PEP as soon as possible. PEP can prevent chronic hepatitis B if caught early enough, so it is very important to inform the doctor of a possible exposure soon after it occurs. If your partner has already completed the 2 dose where available or 3 dose vaccine series, there is nothing to worry about!

They are not at risk for transmission!
