TL;DR

CDC confirms Zika as the first mosquito-borne virus causing congenital malformation, with growing evidence and increasing number of microcephaly cases.

Transcript

you know last week Thomas Frieden the CDC director said there's no doubt that Zika causes microcephaly and he said never before in history has her been a situation where a bite from a mosquito has resulted in such devastating now formation I found that pretty astonishing never before in history what did if you come on that so there's two parts of t...

Key Insights

• 🦟 Zika is the first mosquito-borne virus known to cause congenital malformations like microcephaly.
• 👨‍🔬 Research gaps exist in understanding the full disease spectrum, transmission risks, and potential complications of Zika.
• 💁 The amount of research being conducted on Zika and the transmission of information through scientific journals is commendable.
• 🎮 The emergence of Zika and other viruses highlights the need for a more proactive approach to prevention and vector control.

Questions & Answers

Q: What is the significance of Thomas Frieden's statement about Zika causing microcephaly?

Frieden's statement suggests that Zika is the first mosquito-borne virus to cause a congenital malformation at such a high magnitude. While other viruses like dengue, rift valley fever, and West Nile can cause some complications, Zika's impact is unprecedented.

Q: Why weren't microcephaly cases apparent in the Yap Island outbreak in 2007?

One reason is the lower population in Yap Island, making it harder to identify a significant increase in microcephaly cases. Additionally, there may not have been sufficient registries or tracking systems to capture the data accurately.

Q: What research gaps exist regarding Zika?

Understanding the full spectrum of Zika's disease and its rates, whether asymptomatic mothers have babies with microcephaly, the risk of Zika in babies or young children, and the comorbidities and complications associated with Zika are some significant research gaps.

Q: Why has the emergence of Zika and other viruses caught us off guard?

The general lack of attention and proactive approach to emerging viruses comes from the perception that they seem far away and not an immediate threat. However, in our interconnected world, these viruses can spread rapidly, warranting more focus on prevention and understanding.

Summary & Key Takeaways

• The CDC has now confirmed that Zika virus causes microcephaly, supported by evidence such as identification of receptors in the placenta and fetal brain, and increasing number of microcephaly cases after Zika outbreaks.

• Previous outbreaks, like in Micronesia, may not have seen apparent microcephaly cases due to smaller population size and lack of registries for tracking. Brazil's larger population revealed a significant number of cases.

• The amount of research being conducted and the transmission of information in scientific journals is impressive and necessary to better understand the virus and find solutions.
