Nearly 300 million people have hepatitis b worldwide
A study last Monday (26) by researchers at the Polaris Observatory of the Center for Disease Analysis in the United States revealed a drastic worldwide scenario regarding the HPV virus.
The study shows that by 2016 about 300 million people were infected with hepatitis B virus (HBV) worldwide, at a prevalence of 3.9%, but 90% had not yet been diagnosed and only 5% of those who were to be treated received it.
Pregnant women are at high risk of passing the virus to their children and are the main source of the current epidemic of the disease. According to the study, only 1% of infected pregnant women were being treated properly so that this did not happen.
In Brazil, the researchers estimate a prevalence of 0.4% of the disease in 2016, equivalent to about 760,000 cases. Overall, this figure is one of the best compared to the global scenario.
Of the cases cited in the country, 212,000 (28%) were diagnosed, with 22,500 (12%) of the 184,000 patients eligible for treatment (viral load of more than 20,000 international units of virus DNA per milliliter of blood) in therapy. In contrast, there were no instances of infected pregnant women receiving antivirals to avoid passing the virus to their children.
How to change this scenario?
If hepatitis b is not treated, it can lead to serious health problems, including illness and cancer of liver, causing an estimated 600,000 annual deaths worldwide. But although the virus is extremely contagious, transmitted mainly from mother to child or among children, and has no cure, in recent decades a number of advances have made its eradication feasible: since 1981, a highly effective vaccine is available, and from In 1992, the WHO started recommending the vaccination of newborns, with the first of three doses being administered up to 24 hours after birth.
The hepatitis B vaccine is part of the national vaccination schedule and is mandatory. There are two types of hepatitis B vaccine: the first generation contains virus particles obtained from the plasma of virus donors, inactivated by the formalin; the second generation is prepared by genetic engineering method and obtained by DNA recombination technology (deoxyribonucleic acid).

Dental implants are the options for replacing missing or heavily destroyed teeth. A dental implant provides comfort and stability and, because of the artificial tooth it supports, is the restoration that most closely approximates a natural tooth. Implants are fabricated "anchors" that look like cylinders or screws.
The National Agency of Sanitary Surveillance (Anvisa) has just extended in the country the indication of the Prevenar 13 vaccine, which protects against infections caused by the bacterium Streptococcus pneumoniae, as is the case of pneumonia. Developed by Pfizer, the immunizer was already indicated in Brazil for children up to six years of age and adults aged 50 and over.
