A study in Minnesota found that over half of people diagnosed with chickenpox based on symptoms were actually negative for the virus, with some being infected with other viruses such as enterovirus or herpes simplex virus 1. The decline in chickenpox cases due to vaccination has made clinical diagnoses unreliable, leading to a push for expanded laboratory testing to confirm suspected cases. The study underscores the importance of accurate diagnoses, as those suspected of having chickenpox are advised to stay home longer than those with other viral infections.
The decision not to vaccinate children against chickenpox in some countries has been influenced by concerns about potential consequences, including the risk of shingles in older adults. However, recent evidence has shown that the feared increase in shingles cases has not materialized in countries where the vaccine has been implemented. As a result, the UK has recently recommended adding the chickenpox vaccine to its national childhood immunization program, with other countries also considering similar measures. The availability of the vaccine is seen as a potential game-changer in preventing severe complications and deaths associated with chickenpox.
Shingles, caused by the varicella-zoster virus, can be prevented with the highly effective Shingrix vaccine, recommended for adults over 50 and those with weakened immune systems. The vaccine is free for eligible individuals under Medicare Part D or private insurance. Shingles can cause a painful rash, nerve pain, and serious complications, including vision and balance impairments, facial paralysis, and heart issues. If you suspect shingles, seek medical advice promptly for antiviral treatment and symptom management.
Cases of shingles, an infection caused by the chickenpox virus, are increasing among adults under 50, according to the Centers for Disease Control and Prevention. The cause of this increase remains unknown, but theories include reduced exposure to the virus due to the varicella vaccine and increased stress levels. Shingles can cause a painful rash, along with other symptoms, and can lead to complications such as postherpetic neuralgia and eye damage. Treatment with antiviral medications can help, but prevention is key. Vaccines, such as the Shingrix vaccine, are highly effective in preventing shingles and are recommended for adults aged 50 and older, as well as those who are immunocompromised.
A study suggests that people who are vaccinated against shingles in their 70s may reduce their risk of dementia over the next seven years. The varicella-zoster virus that causes shingles has been linked to an increased risk of dementia. The study analyzed health records of people in their late 70s and older who were living in Wales during the rollout of the Zostavax vaccine in September 2013. People who were eligible for the vaccine were 8.5% less likely to be diagnosed with dementia in the follow-up period, compared with those ineligible.
Sen. Dianne Feinstein and Justin Bieber were both diagnosed with Ramsay Hunt syndrome, a rare neurological disorder caused by the varicella-zoster virus that can lay dormant in the body after chickenpox or shingles. Symptoms include a painful rash, vertigo, tinnitus, and facial weakness or paralysis. Treatment includes steroids and antiviral medication, and early diagnosis and prompt treatment can improve outcomes. About 70% of people with Ramsay Hunt will regain complete or almost complete function of facial muscles, and recovery time can take up to a year.
