A calm, rational reaction to the Zika virus [Pharyngula]
Peter Doherty explains the likely outcomes of the Zika virus pandemic.
What we are seeing in the Americas is a classic “virgin soil” epidemic. Enormous numbers of people and mosquitoes are being infected, the virus is transmitting at a very high level, and there may be as many as 4×106 cases. Apart from affected neonates, all will likely recover, with increasing “background” immunity progressively limiting the number of new infections in subsequent years. The current molecular technology is such that making a protective vaccine should be technically straightforward, but the process of safety testing and evaluation could take several years.
…
The long-term prospect with Zika virus is that we will live reasonably comfortably with it, especially if there is a vaccine to protect women of reproductive age. The principal decision for responsible authorities, like National Governments in endemic areas and the WHO, is whether there is a case for fast-tracking, then funding, a vaccine to protect all young women. For the present, pregnant women are advised not to travel to these countries and, for those where this in not an issue, insect repellant also offers some protection against much nastier viruses like dengue and Chikungunya.
It’s spreading rapidly, and one contributor to that is the ridiculous attitudes of conservative Christianity, but this one, tragic as its consequences can be, isn’t the big pandemic that will kill us all. And the answer to it lies in natural properties of adaptive immunity and vaccines.
