Next week, the hot and happening place to be is in the Kingdom of Saudi Arabia as millions of Muslims gather to complete their pilgrimage to the sacred city of Mecca, a journey known as the Hajj. For public health practitioners within Saudi Arabia and beyond its borders, the Hajj poses serious challenges in the prevention and control of infectious diseases among the millions of faithful worshipers who seek to complete one of the five pillars of Islam.
The Democratic Republic of Congo is home to one of the largest and most biologically diverse rain forests in the world, featuring an incredible variety of animals including bonobos, forest elephants, and mountain gorillas. The country is also the stomping ground of a staggering array of microbial organisms and the region is well known as a wellspring of novel human pathogens, some with big household names and others little known. Some of these diseases, such as HIV/AIDS, have emerged as recognizably major pandemics; others, such as Ebola virus, have been limited to small, localized outbreaks; others still, such as the mosquito-borne Chikungunya virus, pose the risk of becoming new threats to global health.
Maryn McKenna has an unsettling and sobering article at Nature examining the the emergence of carbapenem-resistant Enterobacteriaceae. Since 2002, this large family of bacteria, gram-negative organisms that include many symbionts as well as the gut-dwelling Escherica coli and Klebsiella species that cause hospital infections, are increasingly in possession of a carbapenem-resistance gene rending our best antibiotics useless.
Earth! Fire! Wind! Water! Heart! “Captain Planet and Planeteers” is a classic of 1990s television and may soon appear on the big screen as a live-action movie. The animated television series featured five earnest teenagers equipped with magical powers fighting eco-villains intent on destroying the ozone, rainforest and the wetlands and guided by the sage wisdom of Gaia, the spirit of Earth, and Captain Planet. Today, the program is recognized for its environmental “edutainment” pitch and the emerald-mulleted, square-jawed appearance of its titular superhero.
April! We’ve passed the vernal equinox and spring is springing, flowers are blooming, we’re shedding our sweaters and jackets and all will be warm once again. We can put our winter blues to rest and bask in the knowledge that summer will soon be upon us.
If you ever find yourself working in an infectious disease laboratory, whether it’s of the diagnostic or research variety, the overarching goal is not to put any microbes in your eye, an open wound or your mouth. Easy enough, right? Wear gloves, maybe goggles, work in fume hoods and don’t mouth pipette. When working with pathogenic bacteria and viruses, priority number one is Do Not Self-Inoculate.
My father-in-law David is a dentist and he recently emailed me an astonishing, must-watch video, “The Dentist of Jaipur.” A short documentary by Falk Peplinski that made the rounds of film festivals in 2006 and 2007, the four-minute film shows two men in this famed city in Rajasthan, India practicing dentistry on the streets.
The Pump Handle, an online “water cooler for the public health crowd”, have been publishing a series of articles on Public Health Classics, “exploring some of the classic studies and reports that have shaped the field of public health.” From lead poisoning to the Surgeon General’s 1964 report on the implications of cigarette smoking, the series makes for engrossing material about how our health and standards of living have radically changed due to pivotal research and medical findings.
Uganda and the Democratic Republic of Congo have been bedeviled by viral hemorrhagic fever outbreaks this year. Since the summer, Ebola and Marburg have appeared throughout the two verdant countries killing dozens of people.
It can be hard to comprehend the damage that pathogenic viruses and microbes can inflict on the human body, especially if you have scientists prattling on about cells, using multi-syllabic acronyms and tossing around – god forbid! – actual numbers. It’s helpful to have easily understood images to help put diseases into perspective, to understand that viruses like HIV have tangible and real effects. That’s why I’m so happy to have stumbled upon an incredible image from a 2004 paper that is a pictorial testament to the immunological blitzkrieg that is HIV infection.
