Catching (up with) MERS

Today a MERS case was announced in another country — Italy, where the patient is a man who recently traveled to Jordan (it’s being reported that one of his sons there has similar symptoms). This makes at least fifty known patients with greater than 50% mortality rate. Time to introduce our latest potentially large-scale viral adversary.

Middle East respiratory syndrome coronavirus (MERS-CoV) is one of several coronaviruses humans contract.  In fact, about 30% of cases of the “common cold” are caused by coronaviruses, but with  coronaviruses SARS and MERS, the illness can be far more severe.  Under the electron microscope, MERS looks like this:

It’s deadly.  As of May 29th, the WHO knew of 49 confirmed cases and 27 deaths. That’s a 55% mortality rate compared to the <10% rate of SARS.  (Reuters today says 51 patients with 30 deaths: 58% mortality.)

It can progress quickly. This slide from an article in the New England Journal of Medicine shows the rapid change in four patients, a family cluster of four men who became sick last fall. Two of them died.

We don’t know where it came from, how it can be transmitted, or much else.  The assumption is that there’s an animal source, but that hasn’t been found.  We know it can be transmitted from person-to-person, but not exactly how that happens or how contagious MERS is.  Those aren’t the only puzzles. As Laurie Garrett wrote about the case above, “The cluster of cases in this family presents a list of mysteries: Why were all the sick and dead men? With 28 people in this three-building urban household, why were these four infected, and the other 24 spared? The family lived in a big city, had no animals, ate supermarket food and had jobs that offered no contact with the virus. How did they catch MERS?”

The incubation period may be substantial.  A study of French cases of MERS released online by The Lancet yesterday estimates one incubation period as 9-12 days. This calls for longer isolation than expected and raises the risk that the virus will spread as people who don’t yet feel sick travel.

It’s centered in a troubled area.  It’s called Middle East respiratory syndrome for a reason: all currently known cases originated there (one transmission is known to have taken place outside of that region, but from a patient infected there). Millions of Syrians have been displaced during their civil war and many refugees are crammed together in camps, like this one in Jordan that was featured on yesterday’s PBS Newshour.  If the virus were to get a foothold in a place like that, it could quickly overwhelm the medical resources for refugee care.

World No Tobacco Day

Today is the World Health Organization’s World No Tobacco Day

WHO World No Tobacco Day

I’m not entirely comfortable with the WHO’s approach, though I agree with the goal.  Another poster asks, “Are you being manipulated?” which could suggest tobacco users are gullible, weak-willed followers.  It’s standard to refer to tobacco use as an epidemic and that has been the case for decades, but I struggle with drawing a line between what is and what is not an epidemic.  And, I’m skeptical about the lure to imitate movie smokers nowadays, but that could be an ethnocentric view: I grew up in a culture where the damage caused by smoking was well-known and taught to us at an early age — making movie smoking nothing more than character development — and at a time when TV and radio ads were banned.  It was a long way from 1950:

On a related note, this seems like the perfect opportunity to link to Quit Tobacco International, a project focused on tobacco use in India and Indonesia and founded by, among others, anthropologists Mark and Mimi Nichter.  From the site:

Over the next two decades, deaths due to tobacco will soar to 4.2 million annually in Asian countries, nearly twice that of more developed regions. The wealth of research knowledge and lessons learned about tobacco cessation from high income countries cannot be simply transferred into low and middle income countries (LMICs) given the vast differences in cultural norms, tobacco products and use patterns and health care and public health systems.

Meeting the needs of child trafficking survivors

When a child has endured sexual trafficking, his or her problems can endure for a lifetime. Seeing this as a public health issue, the Johns Hopkins Bloomberg School of Public Health, the Advisory Council on Child Trafficking, and Goldman Sachs 10,000 Women organized the “Symposium on Meeting the Needs of Child Trafficking Survivors” earlier in May.

Seventeen videos of presentations from the symposium are available online. I’m grateful whenever an organization shares material like this so that more of us can learn from it. The few videos I’ve watched so far are interesting and thought-provoking.

Blogs by people with multidrug-resistant TB

One of the sessions at today’s MSF Scientific Day conference is about the MSF’s TB & ME project, a site featuring blogs by people around the world who are undergoing treatment for multidrug-resistant tuberculosis (MDR-TB). The blog provides lots of information about TB and how drug resistance develops, but the focus is on the personal stories of individuals from places as disparate as the UK, Armenia, India, Swaziland and Australia. On the PLOS Medicine blog in 2011, Dr. Phillip du Cros explained the theme of TB & ME like this:

What goes through a person’s mind when they are told they have multidrug- resistant tuberculosis (MDR-TB) and face at least eight months of injections and nearly two years of medication? What are they thinking when they find out that the drugs they have to take will make them feel sick, and the side-effects they will experience could range from severe to life-threatening?

The stigma of having TB can be severe. An infected person must be isolated or wear a mask and in some cases, the weakness of a TB patient can be mistakenly seen as a sign of AIDS. TB & ME has a number of posts tagged with the keyword “stigma” which provide some insight into what it’s like to live with this disease.

The patient experience matters. That seems obvious to those of us with an anthropological mindset, yet it seems that it’s overlooked or disregarded far too often. This project is refreshing and the bloggers are powerful advocates simply by telling their own stories. I wasn’t able to watch the conference session that analyzed the effects of blogging on the patients, but the presentation slides are online and suggest that they felt more empowered, had a sense of solidarity with other patients, were more likely to adhere to the treatment, and that blogging enhanced the relationship between the patient and medical staff. I’ll post a link to the video of the session when it’s online.

The last lepers, and the lack of African surgeons: two articles in The Atlantic

The Atlantic had two good articles out over the winter break that I’m just getting to now; I’m posting them here not because they’re extraordinarily well-written or insightful, but because they’re about topics that deserve greater attention.

The first considers leprosy and the difficulty of eradicating a disease.  In medical anthropology class, I had mentioned that in human history we have successfully eradicated only one disease (of humans) globally: smallpox.  Given our resources in global health in the 21st century, why is it so hard to accomplish the eradication of disease?

Leprosy is a good example of how hard this push can be.  It’s hard to study and the routes of transmission aren’t that well understood (not unlike its close relative, Buruli ulcer).  Worse, it develops very slowly, is easily misdiagnosed, and treatment efficacy is limited.  And social stigma, although its role can easily be exaggerated (something we’ll be thinking about in class), has also played a significant role in rendering the disease and its victims invisible.

The second article concerns a topic that badly needs more discussion: the astounding lack of qualified medical personnel to treat sub-Saharan African populations (the article references a study that finds 9 surgeons per 6,000,000 people in Sierra Leone; I would guess that this is only slightly lower than the West African average).  The results are predictably horrific: inadequate care, malpractice by the undertrained and/or under-equipped, and a system that has little power to retain the qualified.  It’s not a perfect article, but I’m glad that it does two things beyond simply raising the subject: it references Paul Farmer and Jim Kim’s paper on the need for surgeons in the developing world; and it mentions that half of US foreign aid in global health goes to getting ARVs for the HIV+, but a negligible amount goes to training qualified surgeons in poor countries.  Many doctors I work with themselves note this strange disparity between funding and the most pressing medical needs.

The HIV/AIDS epidemic in China

If I were asked to guess a country where AIDS is exploding, China wouldn’t come immediately to mind, but it should.  There was an 8.6% increase in the number of AIDS-related deaths in China last year; of those that were reported and/or acknowledged.  The percentage of cases might appear low in a country with an enormous population, but the number of affected people is high: over 68,000 new cases of HIV/AIDS reported in the past year.

CNN provides an overview of the current situation in China, touching on the years that the government denied there was a problem and their current policies, in the article The price of blood: China faces HIV/AIDS epidemic.

For more information on the current state of global HIV/AIDS, the 2012 report from UNAIDS is full of interesting data and impressive infographics.

Quitting tobacco

From Micah in March:

Next week we’re reading (again) from my friend and mentor Mark Nichter.  He and his wife (Mimi Nichter, also an amazing medical anthropologist) have been working for decades on the problem of tobacco use- which is arguably the largest cause of easily preventable death and disease ever.  Smoking will be the cause of 1/3 of all deaths in the next 20 years, and those dying from tobacco use are increasingly Indians, Chinese and Indonesians.

WHO study on surviving premature birth

http://www.who.int/pmnch/media/news/2012/introduction.pdf (just the TOC and some main points, unfortunately)

Big study (WHO, UN) argues that many more infants can survive prematurity (the single largest cause of newborn death) if parents use basic strategies and treatments.  A quick scan yields some interesting points:

-Looks like two semi-separate issues: prematurity among the well-off driven by rising caesarean rates and older mothers, among the poor driven by malaria, infections, absence of prenatal care and teen mothers.

-Although it seems like a lot of the problem is getting basic treatment (like antenatal corticosteroids) to poor people and fostering prenatal care, the report (and media coverage of it) place a good deal of emphasis on education, particularly on overcoming perceptions that premature or sickly infants are doomed (Think of Death without Weeping).
