STD Awareness: The Syphilis Outbreak’s Youngest Victims

Posted on by

Arizona is officially in the midst of a syphilis outbreak that in 2018 claimed the lives of 10 infants. That’s the most babies to die of congenital syphilis in the state’s recent history. In addition to the 10 deaths, another 43 babies were born with syphilis, which can cause severe health problems.

The word “congenital” simply means the baby was born with syphilis after acquiring the infection in the womb. The bacteria that cause syphilis can cross the placenta to reach the fetus — and will do so in 80 percent of pregnancies in which syphilis is untreated. As many as 40 percent of babies infected with syphilis during pregnancy will be stillborn or will die soon after birth. The condition can also cause rashes, bone deformities, severe anemia, jaundice, blindness, and deafness. The good news is that congenital syphilis is almost completely preventable. When it is administered at the appropriate time and at the correct dosage, penicillin is 98 percent effective.

Prenatal care must include screening for syphilis, which can be cured with penicillin but can be deadly if not treated.

Syphilis used to be the most feared STD out there, but rates have been plunging since the discovery of effective antibiotics during the first half of the 20th century. By 2000, syphilis rates hit an all-time low, and many health experts thought the United States was at the dawn of the complete elimination of the disease. But it’s been making a comeback, and between 2013 and 2017 nationwide congenital syphilis rates more than doubled, with the number of affected babies at a 20-year high.

Areas in the southern and western United States have been especially hard hit. Arizona has the sixth-highest congenital syphilis rate in the country, after Louisiana, Nevada, California, Texas, and Florida. Our congenital syphilis rate doubled between 2016 and 2017 — in terms of sheer numbers, most of these cases originated in Maricopa County, but officials say it’s disproportionately affecting rural areas. Gila County, which is east of Phoenix and home to the old mining town Globe, has the highest syphilis rate in the state. Continue reading →

Why Do Newborns Need the Hepatitis B Vaccine?

Posted on by

The first vaccine a baby receives — within hours or days of birth — protects them from hepatitis B virus (HBV). In a lot of people’s minds, HBV is associated with drug use and sexual activity — which stigmatizes people who have been infected with HBV or are carriers of the virus. Unfortunately, this stigma causes a lot of people to question why babies even need to be vaccinated against it, often pointing to “Big Pharma” conspiracy theories. A lot of other people are put off by the misconception that the HBV vaccine is made with human blood (it’s not).

May is Hepatitis Awareness Month, a time to learn about a childhood vaccine that’s saved millions of lives.

There are perfectly good reasons to vaccinate babies against HBV, mainly that HBV is the leading cause of liver cancer, itself one of the Top 10 types of cancer worldwide. Nine out of 10 infants born to a mother who is an HBV carrier will develop chronic infections and become carriers themselves — and a quarter of them will die prematurely of liver disease. Babies who develop chronic HBV infections are 63 times more likely to develop liver cancer than non-carriers, a connection that is 2 to 3 times stronger than the link between smoking and lung cancer.

When it comes to HBV, age at infection matters. Most people with chronic HBV infections are exposed at birth or in early childhood, when they are most likely to develop chronic, lifelong infections — whereas only 2 to 6 percent of infected adults will develop chronic infections, with only 15 percent of them eventually dying from liver disease. The fact that chronic infection risk is inversely correlated with age at infection means that birth is the time when a child is the most vulnerable to this virus — hence the importance of vaccinating as early as possible.

Hepatitis B Vaccine: The Importance of the Birth Dose

Posted on by

babiesDid you know that Saturday kicked off National Infant Immunization Week, which is part of a worldwide observance that shines the spotlight on the importance of vaccination? Most of us think of infant immunization as a tool to protect babies from childhood illnesses like chickenpox and whooping cough. But did you know that one infant immunization protects them from cancer later in life?

Globally, hepatitis B virus (HBV) is one of the top causes of cancer. Every year, it kills more than three-quarters of a million people worldwide. An HBV infection might be defeated by the immune system, but when it’s not, it can become a chronic infection. And chronic infections can lead to serious health outcomes, including cirrhosis and liver cancer. The younger you are, the less likely you’ll be able to fight off an HBV infection — 90 percent of infants infected with HBV will develop chronic infections, and 25 percent of them will go on to die prematurely after developing liver disease. Compare that to 2 to 6 percent of infected adults who will develop chronic infections.

Because infants are so vulnerable to developing chronic infections, vaccinating them against hepatitis B at birth makes sense.

Most people think of hepatitis as a bloodborne disease, and it is spread very efficiently when IV drug users share needles, during needle-stick accidents and other occupational injuries, or by using contaminated piercing needles, tattoo equipment, or acupuncture needles. Even sharing items like razors, toothbrushes, and nail clippers can do it, as the virus can survive outside of the human body for a week. HBV can also be spread by sexual contact, including vaginal and anal sex.

Lastly, babies and children can be at risk as the virus can be transmitted from mother to infant during birth, and during early childhood when risk of chronic infection is high. A significant number of people with chronic infections acquired them during early childhood, but we don’t know exactly how they got them, as their parents and other household contacts were negative for the virus or its antibodies. Since infants and children are at the highest risk for developing chronic infections, focusing on that population for prevention is very important.

Luckily, there’s a vaccine. Continue reading →

National Infant Immunization Week: A Timely Reminder to Protect Your Child

Posted on by

babyVaccinations, or immunizations, are important for the health of your baby. National Infant Immunization Week, in its 20th year, continues to educate and inform parents of this important information. In the first two years of your infant’s life, vaccines can protect against 14 diseases.

How wonderful that science enables us to protect our little ones from serious diseases like polio, tetanus, and diphtheria!

Under five years of age, a child’s immune system is not developed enough to defend against some infections that can cause disability and even death. Vaccination schedules for infants are designed to protect them at times when they are most vulnerable to potentially serious diseases — diseases that are easily transmitted and quickly overwhelm an immature defense system. Vaccines contain “germs,” such as inactivated or weakened bacteria or viruses, that can stimulate an immune response. The amount and type of “germs” in vaccines are designed to help infants’ immune systems develop protection from the serious consequences of getting that disease.

Watching your baby undergo painful injections that may give them some uncomfortable reactions like fever and aches can make any parent worry, but these short-term effects are much less serious than getting the disease. For example, mothers — who may not even know they have hepatitis B because they do not show symptoms — can transmit the disease to their baby during childbirth. Years later, that child may develop serious liver disease. By routinely receiving a hepatitis B vaccine at birth, babies are protected from this life-threatening disease. Continue reading →
