This virus was first identified in the 1950s, and since then, much research has been conducted to better understand its causes, effects, and treatments. The discovery of VZV began with a study conducted by Thomas Weller and John Enders. In 1954, they were able to isolate the virus from a patient and discovered it was the cause of chickenpox.
This finding was supported by additional research and eventually led to the development of a vaccine to prevent it. In the early years, research into VZV focused primarily on understanding its transmission and effects. For example, in 1957, researchers found that the virus could be passed from person to person through direct contact or through airborne droplets. Further research showed that children were more likely to be affected than adults and that there were differences in symptoms between adults and children.
In the 1960s and 70s, research shifted towards developing treatments for VZV. The first treatment developed was acyclovir, which is an antiviral drug used to treat shingles. This drug was effective in reducing the severity and duration of the disease. Additionally, vaccines were developed to prevent chickenpox and shingles.
These treatments have been improved over time, leading to better results for those affected by VZV. In recent years, research has focused on understanding the long-term effects of VZV and developing better ways to prevent it. For instance, studies have shown that people who have had chickenpox are at an increased risk of developing other conditions such as shingles or postherpetic neuralgia later in life. As a result, doctors now recommend that people who have had chickenpox get vaccinated against shingles to reduce their risk of developing these conditions.
Understanding of VZV has also advanced over time due to technological advancements such as genetic sequencing and new imaging techniques. This has allowed researchers to gain a better understanding of how the virus is transmitted and how it affects the body.
