Zika vaccine tests a major success

<p>Results from a major study published in the medical journal <a href="http://www.nature.com/nature/index.html" target="_blank"><span style="text-decoration: underline;"><strong>Nature</strong></span></a>, suggest a safe and effective vaccine against the Zika virus might not be too far away.</p> <p>The study found that two of the prototype vaccines tested on lab mice, provided complete protection against the Zika virus with just a single shot.</p> <p>Dr Dan Barouch, director of the Harvard Medical School’s Centre for Virology and Vaccine Research, who co-authored a paper in Nature, said, “These findings certainly raise optimism that the development of a safe and effective vaccine against Zika virus for humans may be successful.”</p> <p>The vaccinated animals reportedly showed no evidence of an active virus after being infected with the Zika virus, meaning both vaccines were effective and safe.</p> <p>Dr Barouch said human trials of the vaccine should commence as soon as possible.</p> <p>This study comes as good news as concerns regarding the spread of the Zika virus from August's Rio de Janeiro Olympics heighten.</p> <p>What’s your take on the Zika crises?

Experts warn against visiting Disney World due to Zika fears

<p>If you’ve got a big US holiday planned with the family coming up, you’ll definitely want to read this. Experts are warning against travel to Disney World, fearing the Zika virus may soon make its way up to the US state of Florida.</p> <p>The “Happiest Place on Earth” has long been a favourite destination of families around the world, but travellers are being advised to avoid the amusement park for fears that Zika may start spreading to Florida, Texas, Louisiana and other southern US states in the next few months.</p> <p>Given these states have a high population of the yellow fever mosquito (the main species responsible for Zika transmission), it’s expected they will be the first to succumb to the insidious virus.</p> <p>Scientists believe that while the majority of people shouldn’t be affected by the virus, those who are pregnant or trying to become pregnant should be very cautious in choosing their holiday destinations.</p> <p>Speaking to the <a href="http://www.dailymail.co.uk/news/article-3614551/Zika-expert-warns-Britons-think-twice-trips-Disney-World-virus-set-reach-US.html" target="_blank"><em><strong><span style="text-decoration: underline;">Daily Mail</span></strong></em></a>, Zika-expert Professor Jimmy Whitworth of the London School of Hygiene and Tropical Medicine said that those travelling to Disney World within the next few weeks should be fine, but any later and it might be time to consider changing their plans. “We don’t think there’s any Zika in mosquitoes in the US right now,” he said. “But will there be, in two or three months’ time? Well, there might be, as the situation might change.”</p> <p>The virus, which causes microcephaly in newborns, is currently present in much of the Caribbean, parts of Central and South America and the Pacific Islands.

Should you be concerned about the Zika virus?

<p>As the Zika virus continues to dominate headlines, it can be difficult to figure out how serious the threat actually is. <span>Here are some of the basic facts about the Zika Virus.</span></p> <p><strong>What is the Zika virus?</strong></p> <p>The Zika virus is a mosquito-borne disease, generally transmitted around dawn and dusk. Infections often occur without symptoms but in some cases cause fever, rash, severe headache, joint pain, and muscle or bone pain. There is currently no vaccine to prevent Zika virus and no specific treatment.</p> <p><strong>Is the virus new?</strong></p> <p>The virus has been around at least since the 1940s, first recognised in Uganda in Africa in 1947. At that point there were limited outbreaks but over the course of a few decades it spread across Africa into Asia. And, it recently went into South America in April last year.</p> <p><strong>Why is this most recent South American outbreak different?</strong></p> <p>Experts have suggested the region’s populous cities, prevalent mosquitos and lack of prior exposure are what has contributed to making this outbreak so different to the others.</p> <p><strong>How does it cause birth defects?</strong></p> <p>The link between the Zika virus and birth defects is actually not yet proven, but experts have suggested that evidence is compelling. University of Sydney Infection Prevention and Control Clinical Lead Lyn Gilbert told the Huffington Post, “Although it isn't exactly proven there’s very strong epidemiological evidence largely in Brazil that infection during pregnancy can lead to fetal infection and the unpleasant complication of microcephaly in which the fetal brain fails to develop normally and the baby's born with a small head.”</p> <p><strong>To avoid Zika, where can I and can't I travel?</strong></p> <p>The following map from the Centre for Disease Control shows the areas where Zika transmission is active. </p> <p><img width="500" height="298" src="https://oversixtydev.blob.core.windows.net/media/14860/zika-virus_500x298.jpg" alt="Zika Virus" style="display: block; margin-left: auto; margin-right: auto;"/></p> <p><strong>Related links:</strong></p> <p><span style="text-decoration: underline;"><strong><em><a href="/news/news/2016/02/hero-dog-saves-man-from-deadly-snake/">Hero dog saves man from deadly snake</a></em></strong></span></p> <p><span style="text-decoration: underline;"><strong><em><a href="/news/news/2016/02/things-you-can-do-with-a-binder-clip/">15 things you didn’t know you could do with a binder clip</a></em></strong></span></p> <p><span style="text-decoration: underline;"><strong><em><a href="/news/news/2016/02/swiss-government-may-pay-everyone-whether-they-work-or-not/">Swiss government may pay every citizen $3,500 a month whether they work or not</a></em></strong></span></p>
