Last year a young child came down with onchocerciasis in northern Arizona. Onchocerciasis, is caused by a filarial worm similar to dog heartworm and the roundworm that causes elephantiasis. This child had a dog-related species (Onchocerca lupi) of the roundworm in her neck next to her spinal cord and was the first documented case in the [...]
I thought I’d do a series on some interesting tropical diseases over the next few weeks. Let’s start with a disease called filariasis- which can cause something called elephantiasis. You’ve probably heard of a disease in dogs called heartworm. It’s caused by tiny thread-like worms called microfilariae. Like many diseases, there’s a similar disease that [...]
Last year, a new SARS-like virus called Middle East Respiratory Syndrome coronavirus (MERS-CoV) broke out in Saudi Arabia. Since then, 94 cases of the very lethal disease have been reported by the World Health Organization (50% of the cases have been fatal). All the cases have been on the Arabian Peninsula. The virus causes severe [...]
Last month the World Health Organization (WHO) began to receive reports of human cases with SARS-like infections caused by a new coronavirus. According to WHO, 30 cases of this new illness have been found and 60% of the infections have been fatal. So far, the cases have been limited to Saudi Arabia, Qatar, Jordan, the United Arab [...]
This Spring marks 10 years since Severe Acute Respiratory Syndrome (SARS) arrived on the global public health scene. It started as a mystery illness in SE Asia- without name, origin, or cure in February of 2003. The CDC immediately began working with the World Health Organization to investigate the outbreak. Public health scientists across the globe [...]
Just as our influenza season winds down (and it is), it's time to plan for the next one. Every February the World Health Organization convenes a panel of experts to look at the most current data on the circulating flu strains from around the world and makes recommendations for the next season’s Northern Hemisphere flu vaccine. [...]
The Southern Hemisphere has its flu season during our Summer- so every year around now we watch influenza activity “down under” to get an idea of what we might expect for our upcoming flu season. Here’s the scoop right now. Flu south of the equator has already peaked and continues to decline. There’s been a [...]
The first thing that you learn in a Toxicology 101 class is the old saying coined by the Renaissance German scientist Paracelsus that: "All things are poison, and nothing is without poison; only the dose permits something not to be poisonous." We've shortened that to: 'the dose makes the poison". Anyway... a key question for [...]
The FDA approved the 2011-2012 influenza vaccine this week. The strains in this year’s vaccine were recommended by the CDC and the World Healthy Organization after studying virus samples collected from around the world to find the influenza viruses that are the most likely to cause illness during the upcoming flu season. The strains selected [...]
The World Health Organization International Agency for Research on Cancer met this week in Lyon, France to analyze health-risk data regarding the electromagnetic fields generated by cell phones. Their initial report was published this week, concluding that the chronic use of cell phones could be “possibly carcinogenic to humans”. The group didn’t do any primary [...]
