Public Health Alerts provide concise, data-driven information on disease outbreaks and urgent health events. The new series, launched by NEJM Evidence and CIDRAP, offers expert-reviewed reports to support public health evidence-based care.
Researchers discovered a new evasion strategy used by the varicella zoster virus to affect tissues far from the original site of infection. The virus uses small extracellular vesicles (sEVs) to package and shuttle a protein called IE62, which can travel to distant cells and shut down their antiviral response.

A new study published in the Journal of the Pediatric Infectious Diseases Society finds that US chickenpox cases have declined by 93% since the introduction of the vaccine in 1995, thanks to increased vaccination coverage. This decline is attributed to herd immunity, which protects those who are not immunized themselves.
Researchers at Bar-Ilan University develop novel experimental model that successfully mimics the re-activation of the varicella-zoster virus, which causes chickenpox and shingles. The model allows scientists to test drugs and develop therapies to prevent shingles and potentially impact other viruses targeting the human nervous system.
A new study finds that shingles significantly increases the risk of stroke in the first six months after symptoms appear. However, patients treated with oral antiviral medication for their shingles may experience lower stroke risks compared to those not treated.
A 14-year study found the varicella vaccine to be approximately 90% effective in preventing chicken pox, with a significant decrease in breakthrough cases over time. The second dose of varicella vaccine was found to be unnecessary for prevention of moderate to severe disease.
A national study of chicken pox admissions found a 68% drop in hospitalizations since the introduction of the vaccine in 2006. The results show that unvaccinated children were more likely to require intensive care treatment, highlighting the importance of herd immunity.
A Kaiser Permanente study found that receiving the herpes zoster vaccine reduced the risk of shingles by 55% in adults 60 years and older. The vaccine also showed effectiveness in preventing shingles in adults over 75, supporting CDC recommendations to offer it to all eligible patients.
A new study confirms that two doses of the varicella, or chickenpox, vaccine provide excellent protection in children against this highly contagious and, in some cases, severe disease. The study found that the effectiveness of two doses of vaccine was 98.3 percent in protecting against varicella, significantly higher than one dose.
A study published in Journal of Infectious Diseases found that children who received two doses of the varicella vaccine had a 95% lower risk of developing chicken pox. The effectiveness of two doses was 98.3%, significantly higher than one dose at 86%.
A Kaiser Permanente study found the MMRV vaccine doubles the risk of febrile seizures in 1- to 2-year-old children compared to separate MMR and varicella vaccines. The study analyzed 459,000 children and recommended that families without a preference for MMRV receive separate vaccinations.
A study found that refusing the varicella vaccine is associated with a nine-fold increased risk of developing the disease in children. This finding suggests that declining vaccination rates could lead to an increase in the incidence of chickenpox and related complications.
A Kaiser Permanente study found that the chicken pox vaccine significantly reduces the risk of shingles among children. The study followed over 170,000 vaccinated children for an average of two and a half years, resulting in only 122 cases of herpes zoster.

New research from the Mayo Clinic suggests that shingles and its complications may have a greater impact on healthy adults than previously thought. The study found that shingles affects at least 1 in every 278 adults each year, with post-herpetic neuralgia being the most common complication, especially among older adults.
Research published in Archives of Disease in Childhood found that severe chickenpox complications occur in hospitalized UK and Ireland children. Vaccination is key to preventing deaths and severe disease.

The study found that both term and preterm infants reached a level of immunity considered protective against these diseases.
A team of NIAID scientists identified a human protein that helps varicella-zoster virus spread from cell to cell. Interfering with this interaction inhibits the virus' spread, and blocking it may lead to new therapies for shingles.
Children undergoing steroid treatment for childhood leukemia are at increased risk of contracting a more severe form of chicken pox, which may result in death. The study found that 54 out of 110 patients with chicken pox experienced severe disease, including two deaths.
Since the introduction of the varicella vaccine, hospitalizations due to chicken pox have decreased by 88% and ambulatory visits by 59%, according to a recent study. These declines are observed across all age groups, with infants under 1 year experiencing the most significant reductions in hospitalizations.
A stronger version of the chickenpox vaccine has been shown to prevent shingles in older adults, reducing incidence by 51% and total burden of pain by 61%. The vaccine also significantly reduces postherpetic neuralgia, a debilitating form of chronic nerve pain.
The varicella vaccine has significantly reduced the number of chickenpox cases and deaths from varicella, with a 66% decline in mortality. However, its impact on herpes zoster incidence, age distribution, and severity remains uncertain, emphasizing the need for continued vaccination programs.
The chicken pox vaccine has resulted in a 74% decrease in national hospital discharges for the disease, saving $100 million annually. Herd immunity also protects unvaccinated individuals, leading to lower hospital costs among teens and adults.
