Scientists take step towards drug to treat norovirus stomach bug

Scientists take step towards drug to treat norovirus stomach bug | Virology News | Scoop.it
Norovirus is the most common cause of gastroenteritis in the UK. For most people, infection causes an unpleasant but relatively short-lived case of vomiting and diarrhoea, but chronic infection can cause major health problems for people with compromised immune systems. In many cases, patients who have weaker immune systems suffer from norovirus infection for months to years, with some patients experiencing gastroenteritis for as many as eight years.
Ed Rybicki's insight:

Interesting: the same drug used to treat influenza, West Nile virus, yellow fever virus, and foot-and-mouth disease virus??

‘Let them eat cake’: A dangerous approach to bushmeat and Ebola

‘Let them eat cake’: A dangerous approach to bushmeat and Ebola | Virology News | Scoop.it
Let them eat cake—is the phrase supposedly uttered by a great princess (though often attributed to Marie Antoinette) upon learning that France’s peasants had no bread.
This is a similar response, in our estimation, to what seems to be permeating from certain quarters with respect to the consumption of bushmeat and its links to the outbreak of Ebola virus disease (formerly known as Ebola haemorrhagic fever).
A number of opinion pieces have appeared in reputable magazines such as New Scientist and
Ed Rybicki's insight:

Nice sober article about the mistake in making the kneejerk response of stopping people eating bushmeat - although if they don't, there won't be a lot left, quite soon.

Scientists unlock exact structure of Hepatitis A virus

Scientists unlock exact structure of Hepatitis A virus | Virology News | Scoop.it

Scientists have announced that for the first time, they have determined the precise atomic structure of the Hepatitis A virus. In an unprecedented step forward, a team of scientists from Beijing and Oxford have been able to map the exact construction of Hepatitis A, down to the individual atoms. 

This discovery is ground-breaking in terms of what it reveals about the history and evolution of viruses. The findings suggest that Hep A may be the evolutionary 'missing link' between picornaviruses, which infect humans and animals, and some insect viruses.

Resurrecting Smallpox? Easier Than You Think

Resurrecting Smallpox? Easier Than You Think | Virology News | Scoop.it
The virus’s genome is already online. You just need the right lab.
Ed Rybicki's insight:

Weeeeeellll...yes and no. Smallpox is a BIIIIG genome - not far off in size to the bacterial genome famously resynthesised by Craig Venter et al., a while ago.  This means it would be a huge undertaking, cost a LOT of money, and need sophisticated facilities to do it.

Not something your average cave-dwelling fanatic could do, then!

States could do it, however: a well-funded lab in even a country like North Korea could theoretically resynthesise a poxvirus - but why bother??  We have vaccines against smallpox right now; growing poxviruses and vaccinia virus in particular is a well-established biotechnology still.

SO I think this is an artificial concern, to be honest.

The Apocalypse as a Rhetorical Device in the Influenza Virus Gain-of-Function Debate

Humans are notoriously poor at assessing future benefits and risks. Consider nuclear power, which was born from a program to develop a weapon of mass destruction. When nuclear power was developed for commercial purposes, the risk was thought to be minimal and no one anticipated the disasters at Three Mile Island, Chernobyl, and Fukushima. On the other hand, no one initially anticipated the benefits of radioactive nucleotides and radiation in medicine, archeological dating, smoke detectors, and sterilization of food and medical devices. In the mid-1970s, scientists fretted that recombinant DNA technology would unleash a plague of new infectious diseases and convened a conference at Asilomar that put in place a self-enforced moratorium until the process was better understood (1). Four decades later, no superbugs have appeared from recombinant DNA technology, and society is reaping the rewards of the molecular biology revolution in new drugs, DNA identification, personal genomics, and pest-resistant plants. In the late 1990s, many worried about the Y2K computer bug, which it was feared would cripple computer systems and associated infrastructure such as banking, but the new millennium came and went without a ripple. Today we have falling rates of vaccine acceptance because of widely believed yet discredited associations between vaccination and autism, with overwhelming evidence demonstrating that vaccines are safe and effective. Consequently, diseases that were considered controlled, such as measles, have become endemic again. These examples suffice to make the point that when assessing risks and benefits, humans need to be extremely humble, for their prediction record is poor.

I have to humbly thank Alan Cann, for this too-good-to-ignore title - and pretty good paper, as it happens!

The Influenza Epidemic of 1918

World War I claimed an estimated 16 million lives. The influenza epidemic that swept the world in 1918 killed an estimated 50 million people. One fifth of the world's population was attacked by this deadly virus. Within months, it had killed more people than any other illness in recorded history.
