Salmonella may well be one of the most disreputable microbes in Western society. It’s infamous for its food-poisoning capabilities and has a well known history of wrecking the bonhomous vibe following a good summer barbecue, not to mention its singular ability to cast a sickly shadow over the breathtaking bounty of an all-you-can-eat buffet.
The public health game is a tough one to play. How do you achieve educating and transforming the public’s behavior for the common good without coming off as a bully or dour spoil-sport? The stakes are impossible: The indifferent audience, the management of the reproachful “tsk-tsk, you should know better” tone, and there’s only so many ways to proselytize a message of “getting one’s act together.” And where’s the cash for such endeavors?
Hanuman is a pivotal and memorable character in the Hindu epic poem, the Ramayana. Known for his faithful devotion to Rama, the monkey-king is famous for rescuing Lord Rama’s bride Sita after she is kidnapped by the demon king Ravana, all the while defeating his demon army as commander of his monkey army. Hanuman is revered throughout south and southeast Asia not only for his devotion to Rama, but also for his steadfast spirit, his indefatigable strength, and his noble humility. He is also something of a rogue – the Coyote, the Loki, the trickster of Hindu mythology, the mischievous troublemaking deity with a heart of gold and a glint in his eye. Read More
Well, it’s here. The mosquito-borne chikungunya virus finally trekked its way into the Western Hemisphere, arrived in the Americas, and has begun infecting Caribbean mosquitoes, confirming one of the worst fears of public health officials on this side of the prime meridian. This pathogen, notorious for its explosive outbreaks and debilitating joint pains, arrived on the Caribbean island of Saint Martin and has caused over 200 infections since December 5 of 2013. The outbreak marks the first time that chikungunya has been locally transmitted by native mosquitoes in the Americas.
Successful World War II-era campaigns to eradicate dengue has kept the United States free from the mosquito-borne virus for almost forty years but the virus is making a comeback and we have globalization to thank: an increased flow in international travel to and from tropical destinations are causing isolated outbreaks in Hawaii, Texas, and Florida. Just last week, Texan public health officials confirmed 18 cases of dengue in the southernmost tip of Texas and a recently discovered case in Long Island, NY suggesting that the virus, dubbed “breakbone fever” for its excruciating aches and pains, is gaining an unwelcome foothold in the States.
The plague is an old microbial foe that has haunted our cities and our ports for millennia, killing millions of people in waves of pandemics since antiquity. But Yersinia pestis no longer has the same presence, or stranglehold, in our society and seems negligible when we consider the current state of microbial affairs – increasing levels of antibiotic resistance and novel and emerging viral pathogens, just to name a couple of today’s most pressing issues. Even its moniker, “the plague,” has been appropriated for more contemporary microorganisms that appear to come from nowhere and quickly, fatally sweep through a population – SARS and HIV are prime examples of two new “plagues.”
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.
This past June a federal judge ordered the relocation of thousands of prisoners from two prisons in the San Joaquin Valley in California to protect imprisoned men against a small fungus, Coccidioides immitis, that could infiltrate the gated and locked Pleasant Valley and Avenal state prisons and continue to cause isolated cases of a debilitating illness, valley fever.
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.
Microbial Misadventures is a recurring series on Body Horrors looking at instances and incidents where human meets microbe in novel and unusual circumstances that challenge our assumptions about how infections are spread.
Conjunctivitis is spread through particularly artful and gross means – the contamination of objects with eye gunk, smeared inadvertently hither and thither as a person wrestles with the itchy, gritty misery that defines what is commonly known as pinkeye. Many of us know that infectious diseases inevitably come from someone, some one, but we don’t often know from whom. Conjunctivitis is easy enough for the amateur Sherlock or epidemiologist-in-training – find the disconsolate soul with red, dripping eyes and follow the (sticky) trail.
