Snakeflu?! An intriguing source suggested for new Chinese coronavirus - Infectious Thoughts

Jan 23, 2020

The whole world is on edge over a coronavirus outbreak that started in early December in Wuhan City, China. The virus is thought to have first infected people working at a seafood and live animal market. So what could the original source have been? There’s no official word yet, but that’s not surprising. Sources like this can be incredibly difficult to track down. Especially in a market selling so many different kinds of animals. I can’t even begin to imagine how many samples scientists would have to test! The coronaviruses that cause SARS and MERS are thought to have originated in bats and crossed to humans via civet cats (SARS) and camels (MERS). Now researchers in China have published a study suggesting that this new virus also originated in bats and that it could have crossed to humans from … Read More

The Chinese coronavirus outbreak: what are the options for vaccines and treatments? - Infectious Thoughts

Jan 22, 2020

By now you’ve probably heard of the coronavirus outbreak that started in Wuhan City, China. The number of cases is rising, up to about 300 with six deaths. Cases have been reported in several more Chinese cities, including Beijing and Shanghai, as well as in Japan, Thailand, and South Korea. There are also reports of a case in Australia and another in the USA. For a quick explainer, check out my post here. A few people have asked about whether the virus can be treated with Tamiflu and what the prospects of a vaccine are. I’ll start by saying that as this is a ‘new’ virus, there are no proven antiviral treatments or vaccines. At the moment, people who are ill will be being given treatments to help relieve the symptoms of their infection. But here’s … Read More

The emerging coronavirus outbreak in China - Infectious Thoughts

Jan 21, 2020

By now you’ve probably heard of the new virus causing an outbreak of severe pneumonia in China. The question on most people’s minds is, how worried should we be, especially as hundreds of millions of people will soon be travelling across China and beyond to visit family for the Lunar New Year holiday? The situation is changing daily, but here’s where we’re at as of Tuesday evening. What’s happening in Wuhan City, China? In late December, there was a cluster of cases of pneumonia of unknown cause. Most of the people affected worked at a seafood and live animal market. By early January there had been 44 cases, with eleven of those people severely ill. To date, the number of confirmed cases has risen to over 200 and four people have died. Cases have now been reported in Beijing and … Read More

Open by design, not default. - Infectious Thoughts

Mar 14, 2019

I’m currently taking part in the Culture Track of the Mozilla Open Leaders programme, 14 weeks of mentoring and training by the Mozilla Foundation. I’m hoping to learn how to build an open culture for my lab and other projects I’m involved in. I’ve been interested in the concept of open science/research for a while now. If you haven’t heard of open science, it’s the movement to make more of our research practices, methods, and data accessible than just the stuff that eventually makes it into a scientific journal. That includes all our dead ends and failed experiments. I was so keen to give it a try that in 2013 I convinced my PhD student, now Dr, Hannah Read to document her experiments and data in real time in a sort of open lab book. As her … Read More

The Open Source Period project: my open leadership journey begins! - Infectious Thoughts

Mar 08, 2019

If you’ve not heard of Mozilla, you’ve likely heard of their web browser Firefox. The Mozilla Foundation is a global non-profit that wants to shape the future of the web for the public good. So, what’s Mozilla got to do with the Open Source Period project? For the last seven years, the Mozilla Foundation has run a programme called Open Leaders. Each year a cohort of people are chosen to go through 14 weeks of mentoring and training to “fuel the Internet Heath movement”. I came across the call for applicants for Round 7 of the programme on Twitter last year. I’d been looking around for a mentor to help guide me as I looked to start the Open Source Period project (more on that here). I was so excited to be accepted on to the … Read More

Open Source Period - Infectious Thoughts

Mar 07, 2019

For nearly a year, I’ve been raving about menstrual cups to anyone who would listen, trying to explain how they could disrupt the way many of us do scientific research. Sounds unlikely? Then read on! I had the idea for the Open Source Period project when a story about menstrual cups hit the news in April 2018. To cut a long story short, a new lab-based study was suggesting that menstrual cups users may be at a higher risk of getting the potentially fatal toxic shock syndrome than tampon users. If you are interested in the nitty gritty of what that study showed and what it might mean for menstrual cups users, I wrote about it here, here, and here. The story sent me on a hunt for any other studies that looked at the safety of … Read More

The science behind the Impossible Burger - Infectious Thoughts

Jul 05, 2018

Air New Zealand has just announced The Impossible Burger is now available to a minuscule number of their customers, a move described as an “existential threat” by New Zealand First’s Mark Patterson. So what is all the fuss is about? This week, Air New Zealand announced that Business Premier “foodies” on their Los Angeles to Auckland flights would be able to try out the “plant-based goodness” that is the Impossible Burger. Lamb + Beef New Zealand, which represents sheep and beef farmers, is clearly peeved that our national carrier wouldn’t rather showcase some great Kiwi “grass-fed, free range, GMO free, naturally raised” beef and lamb instead. Mark Patterson, New Zealand First’s spokesperson for Primary Industries even went as far as to put out a press release calling the announcement an “existential threat to New Zealand’s second-biggest export earner”. Meanwhile, vegetarians … Read More

Menstrual cups: let’s investigate! - Infectious Thoughts

Apr 29, 2018

After finding that there really have been bugger all studies done on menstrual cups and toxic shock, microbiologist Siouxsie Wiles ponders whether crowdfunding and open science might be the solution. Last week a new lab-based study came out about menstrual cups and toxic shock syndrome, the very rare but potentially deadly result of infection with the bacterium Staphylococcus aureus. I wrote about what I think the study means here, here and here. One thing that appalled me as I was reading around the topic is that it appears menstrual cups have hardly been studied at all. Or if they have, the findings haven’t been published. I counted 14 relevant studies on the journal article database Pubmed. There’s this new one, an older similar lab-based study, three case studies, and 9 reports of actual clinical trials. Read More

The recent ‘period in a bag’ study: what it can and can’t tell us about menstrual cups and toxic shock - Infectious Thoughts

Apr 29, 2018

Recently, a lab-based study was published about menstrual cups, tampons, and toxic shock syndrome. In this post, microbiologist Siouxsie Wiles reflects on what the study can and can’t tell us about menstrual cups and toxic shock. If you need reminding, toxic shock syndrome is a very rare complication of a bacterial infection that can quickly result in organ failure and death. In a previous post (published here and here) I wrote about one of my take-home messages from the recent study (1): that bacteria may stick to menstrual cups as they are used over the course of a period, and if you just follow the advice of wiping or rinsing after each use, you could be putting a cup inside your vagina that’s becoming more and more covered in potentially harmful bacteria. My advice was to get … Read More

Menstrual cups and toxic shock revisited - Infectious Thoughts

Apr 29, 2018

Last week a new lab-based study came out, about menstrual cups, tampons, and toxic shock syndrome (1). In this post, microbiologist Siouxsie Wiles reflects on the various responses she’s had to her blog about the study.  If you need reminding, toxic shock syndrome is one of the bogey-men every menstruating teen is warned about – a very rare complication of a bacterial infection that can quickly result in organ failure and death. Journalists were soon calling me, asking what the study meant. They all wanted to know, are menstrual cups more dangerous than tampons? As usual, the answer was a little more complicated than a simple yes or no. As a microbiologist, one of the main conclusions I drew from the study was that people who use menstrual cups would be better off cleaning them more rigorously and more … Read More
