Ebola won't be a pandemic
Between 2,000 and 5,000 travelers arrive monthly in the New
York City metropolitan area from the West African Countries currently
struggling to contain the Ebola Virus outbreak. It is highly unlikely though
that an individual infected with the virus will arrive here without the medical
community knowing about him or her.
Any passenger found to be sick on the flight would be reported to the
CDC Quarantine Station by the flight crew and whisked into isolation with full
infection control precautions in place. If the illness starts after arrival all
emergency departments are prepared to isolate the sick traveler and determine
the etiology of the febrile illness. Typhoid fever, cholera and malaria are
infinitely more likely than Ebola.
Of the fifty or so people who have arrived in NYC from West
Africa sick none have even had an illness worrisome for Ebola let alone the
disease. This includes the well-known patient at Mt. Sinai. Should a patient with
Ebola arrive in NYC there would still be little reason for the general public
to be concerned. The primary transmission risk for Ebola is to health care
workers who do not have adequate personal protective equipment and persons
handling infected bodies during burial rites. The health care systems in the
affected countries are both understaffed and under resourced, a problem not
present in NYC (or anywhere in the US for that matter). NYC has the ability to rapidly test
suspect patients, something that isn’t easily done in West Africa. Additionally,
Ebola, unlike say measles, isn’t contagious until after symptoms begin, so
there is time to implement control measures. Ebola isn’t airborne so to be
infected one needs to come in contact with body fluids. The risk of Ebola transmission
is low during the beginning of the illness, therefore hospital infection
control precautions can be put in place in time and reduce the risk to health
care workers. Ebola just isn’t the type of disease to pose a risk to the
general US population. It’s not the Andromeda strain.

New Book The Ratcatcher and the Mole is Coming Soon!
Book three in the Mackey Dunn series is the prequel to Mailaise and introduces Mackey as the protagonist. The story is told through the eyes of Will Benes, a CDC pubic health trainee assigned to the woeful River City Department of Health. Will is the literary nephew of Holden Caulfield, and is a few shavings short of a chip off the old block. In Mackey Dunn he finds a kindred spirit and the only person whose misfortunes seem worse than his own.

Open the door and influenza
Influenza is here. Starting a few weeks before the holidays it began creeping up, not only in water cooler conversations and in sick call phone messages, but in emergency departments and physician's offices. So much so that people began to suspect something was amiss. Is it a new strain? Is there a problem with the vaccine? Today the City of Boston declared an influenza emergency because their hospitals are inundated with flu patients and the intensive care units are full (see link below).
http://gma.yahoo.com/blogs/abc-blogs/early-flu-season-hits-hard-224805500--abc-news-wellness.html
The story in NYC is a bit different. Sure, we've got flu, and plenty of it. One measure used is the number of long-term care facility outbreaks and we've already exceeded the number from all of last season. But thus far doctors and emergency departments are handling the load. If fact, the volume isn't unusual for peak flu season, the issue is that we've forgotten what a normal flu season is like. Last year flu barely touched down in NYC and cases were mild. In fact since the pandemic in 2009 we've had mild flu seasons, so we've forgotten what a mean flu season is like. The strain circulating this year is of the H3 variety, more severe than H1, and it arrived earlier than usual by about a month or so. The strains included in the vaccine are a good match so there isn't concern that the vaccine is any less effective than usual. Trouble is that flu vaccine doesn't work as well in the folks who need it the most, the elderly. But there are other things we New Yorkers can do to protect ourselves and our loved ones.
First and foremost, get yourself and children vaccinated. This will most likely protect you and if you do get ill it will be less severe. Your flu vaccination protects other family members and loved ones, because if you don't get sick you can't give it to grandma in the nursing home. Second, stay home when you have flu symptoms (fever, sore throat, cough, chills). No sense spreading the misery. This goes the same for kids too. And by no means go visit grandma if your are sick. She and her friends are vulnerable to flu and its complications. Wait until you're better. She'll miss you, but then she still be around for your next visit. Flu does kill, up to 50,000 Americans each season, and most are at the extremes of age. Also a good idea if you are not too sick to stay out of the emergency department or your doctor's office. Now if you are pregnant, have a chronic disease or respiratory problem then you should be in contact with your physician at the first symptom, otherwise, tough it out and keep your snot to yourself.
Oh, and don't forget to cover your cough and wash your hands!

The awful legacy of meningitis
Perhaps no illness strikes fear
like meningitis (often referred to as spinal meningitis). I recall during my freshman year in high school that there was
a case in a neighboring town. The kid died and when we learned he was a
wrestler parents and teachers claimed it came from the mat. We were so frightened of the spongy
devil that I swapped my spot in the gym class wrestling line so that I was
matched up with one of the less athletic kids. That way I could pin him in
under a minute and get the hell off the grimy Petri dish.
There are many types of
meningitis. The previous post was
about fungal type, a rare form and related to pain injections. New York City
has thus far escaped having any cases. The most common type of meningitis is
caused by any number of viruses, but the type of meningitis that provokes
community wide anxiety, rumors and regularly makes its way onto the evening
news is a particular type of bacterial meningitis. It too is rare but possesses
two features that have earned its deserved reputation. The first is that it can
spread in group settings, such as schools. The second is that it kills. About one
out of six or seven victims die, rather high in the modern era of public health
and medicine. The name of this modern day scourge is meningococcal disease. The
bacterium responsible is called Neisseria
meningitidis. My job is to track and stop it.
The city is now in the midst of an
outbreak. Not an epidemic of the scale of AIDS or Swine flu. There have been
two dozen cases this year, but five have died. At the center of the outbreak is
the community of men who have sex with men and reside in several Brooklyn
neighborhoods. The health department has been promoting vaccination but it has
been hard to reach the people that most need it. More efforts are being made to
get the word out to those at highest risk.
Family legend is that my
grandfather died of meningitis. I was shy of my second birthday when he died so
I don’t have any memories of him other than from photos and the items from his
medical practice I found in my grandmother’s Grand Concourse apartment. He was
a physician and the story told me by my mother as long as I can remember was
that he could’ve been saved if they had just given him sulfur. I was already my
way to becoming a junior chemist and didn’t quite understand how the yellow
powder I had used to make gunpowder would’ve saved my grandfather. Last year I
decided to investigate the family story, learn if my grandfather really died of
the disease that it is now my job to watch over for the city. It took a few
months but I managed to get his death certificate from vital records. He died
at sixty-six, just a year or two after retiring from his Bronx medical practice
due to hearing loss. The certificate didn’t list the cause of death, however, the certificate had the name of the physician who attended his death. It was a long shot, but I tried to
locate him. The New York State Department of Education, the agency that
oversees physicians, maintains a website where people can verify licenses. I
found the doctor listed. He had graduated medical school in 1957. That made him
at least 80 years old, if he was still alive. The last known address was in
California and the Internet had two doctors with that name in the town listed
in his license record. I dialed the first number and a woman answered. She
confirmed I had the right physician. But his hearing was too poor to converse
by phone. If I would write a letter, he’d be happy to answer my questions.
Meanwhile I learned that the
city’s office of vital records had a more detailed death record. I got my dad
to sign the authorization form for his father’s record and requested the full cause
of death report. I had almost forgotten about it when the letter showed up a
few days before Christmas last year.
I poured over the report. Laboratory
diagnosis wasn’t common when my grandfather Jack died. I would have to confirm
my suspicion without the definitive evidence I was accustomed to having. Jack had
pneumonia and blood poisoning confirming that a bacterium was responsible. But
was it the notorious Neisseria meningitidis?
And then there it was, listed under the Part II. Other Contributing Conditions.
Printed in black ink by the hand of the physician who was at the bedside were the words Waterhouse-Friedrichson
Syndrome. It was the eureka
moment. Waterhouse-Friedrichson Syndrome is hemorrhage into the adrenal glands
and occurs in overwhelming bacterial sepsis, most notably that caused by Neisseria meningitidis. Sulfur, more
correctly the family of sulfonamide antibiotics, would have cured him. If they
could’ve treated him quickly enough. That is the thing with meningococcal
disease. You don’t have much time. I did end up getting a nice letter back from
the California doctor. He had no
recall of ever treating a case of meningococcal disease. I didn’t ask him if he
remembered treating grandfather Jack.
There is a vaccine for
meningococcal disease. Because of questions about its efficacy and cost
effectiveness, the CDC Committee on Immunization Practice only recommends the
vaccine for teenagers up through the college years because studies have shown
they are at an increased risk, particularly if they reside in dorms. But data
from NYC suggests that people living with HIV and AIDS (PLWHA) are at an even
greater risk. Currently there is a particularly nasty strain circulating among
the MSM community and we've worked to insure that vaccine is available to this population at most health centers and city run
clinics.
A few years ago there was a
meningococcal death in a high school student. The circumstances around the case
were particularly heart wrenching.
If you, a friend or a loved one is in the risk category, please get them
the message to get vaccinated.

Compounding Pharmacies
The official case count is up to 105 in the largest outbreak
of fungal meningitis in US history, but it will undoubtedly go higher as more
cases are recognized as being connected to the contaminated medicine (CDC
currently is updating the case counts once a day).
Fungal meningitis is the rarest form of meningitis and it is
not contagious from one person to another. It usually occurs only in people who
have a damaged immune system, like those with AIDS or undergoing chemotherapy. I
heard a TV interview by a doctor, not a public health official, but an
infectious disease specialist. He said we’ve never seen anything like this
before. Well, he’s not exactly correct. A few years back there was an outbreak of
Pseudomonas fluorescens traced to a
compounding pharmacy in Texas. It involved kids with serious diseases, like
cancer, who had indwelling catheters that required periodic flushing wit a
heparin preparation to keep them from clogging. See http://cid.oxfordjournals.org/content/47/11/1372.full.pdf
What are compounding pharmacies? They are a lot like the big
factories that produce food for retail stores. They buy large quantities of medication, like steroids, then
mix them with sterile water or another solution and prepare vials for doctors.
They exist because they can produce the drug at a cheaper price than pharmacies
with more rigorously oversight. The problem is that organisms, mostly bacteria
and fungi, have a way of getting everywhere. Unless you use high tech systems
to ensure absolute sterility mistakes like this can happen. Just like one
contaminated cow can be spread E. coli
to a lot of ground beef one unsterile step in a compounding pharmacy can
contaminate a lot of medicine.
What is odd and concerning is that the injections of steroids
into the spinal column is resulting in meningitis. The goal of the procedure is
to inject the medicine around the nerve root as it emerges from the spinal
cord. Decreasing inflammation by
the use of steroids will reduce pain. Most of the time the placement of the
needle is checked with fluoroscopy and dye. The spinal sac is not penetrated,
which means that the infections in the outbreak are a result of direct fungal invasion
though the spinal cord membrane or via the bloodstream. Both scary situations.

Dying to be beautiful
The quest for beauty and perfection will make people do
strange things. Some might include cosmetic surgery on the list but I think
most would agree that allowing a person who never attended medical school or
any hospital training to operate on you is beyond strange if not foolhardy.
Back in 2010 we were called by an astute and thoughtful
hospital doctor. He was treating a woman who had bilateral abscesses in her
buttocks. When he asked her what had provoked the unusual infection she
confided that she recently had liposuction. When the doctor asked who did the
procedure he was surprised by what he heard. A local Spa operator. Thinking
that a language barrier was preventing him from fully understanding what the
woman was saying he probed deeper. No, she wasn’t a doctor, but had done these procedures many times before. The
patient had allowed the Spa operator to remove fat cells from her abdomen and
re-insert them into her derriere.
Along with detectives from the major case squad we raided
the Queens Spa and confiscated records and drugs. We found a number of
pharmaceuticals that require a license to prescribe, such as botox, and others
that are illegal in the United States. We began calling the patrons to ask if
they were well and to learn the scope of this illegal medical practice and the
harm it might have caused. Five procedures were popular: liposuction, meso
therapy, botox, injection of filler materials and intravenous vitamin
infusions. Bust, thigh and buttock
augmentation with silicone or other industrial-use chemicals was the most
common procedure performed. Meso therapy is the injection of chemicals under
the skin to dissolve fat. It is unproven and can result in infection and
scarring. Quite a few had complications such as scarring, discolored skin and
wounds that didn’t heal. This past spring the Spa owner pleaded guilty and was
slapped with a $400,000 dollar fine and two years jail time. http://www.queensda.org/newpressreleases/2012/may/nieto_05_29_2012.con.pdf
The district attorney sent a message to others involved in
the illegal practice of medicine that putting the public health in danger will
not be tolerated in NYC. It is also a cautionary tale to people seeking affordable
alternatives to plastic surgery.
Sadly plastic surgery by unlicensed practitioners of
medicine is all too common as a simple Web search reveals. And these are just the people who got caught. Costing a fraction
of what real doctors and hospitals charge it is most popular among Hispanic
women. This was our fourth
investigation into illegal medical practice. The woman who was
dissatisfied with her figure learned of the Spa from a friend who informed her that she could get a procedure that usually costs over
$10,000 dollars for $500. What she got for her money was pain, fever, a deep tissue infection and a several day stay in the hospital.
She was lucky, others have not been as fortunate suffering
debilitating pain, chronic infections with mycobacteria, permanent disfigurement and even death. In 2009 a Bronx woman
died of silicone pulmonary embolism from a filler injection. The list of chemicals injected is
appalling as is the lack of safe and sanitary practices. One women used Krazy
Glue to seal a wound (see links below). Cheap cosmetic surgery by an unlicensed
practitioner is dangerous and you get what you pay for. So if you are
determined to improve your appearance save up for a real plastic surgeon or do
it the old fashioned way. Tone those abs and butt at the gym.

Deadly Virus Visits National Park
After an incubation period from one to five weeks the first symptoms to appear that aren’t much different from the flu and include fever, chills, headache and severe muscle aches. Sometimes stomach pain and dizziness occur. Several days later respiratory symptoms appear. The life sustaining oxygen membrane in the lungs no longer works. Fluid collects and patients die of oxygen starvation. Most hantavirus cases in the US have occurred in the southwest but another strain was discovered in Maryland and we have had two cases in New York, the latest was just last year: (http://abclocal.go.com/wabc/story?section=news/local/long_island&id=8211238)
Back in June of 1993 the CDC began testing serum from the Four
Corners victims of SNV against a battery of viruses from across the world
looking for cross-reactivity as a clue to Sin Nombre’s identity. They got reactions
with two viruses from halfway across the world, Haantan and Seoul. These
viruses were discovered during the Korean War and were known to cause kidney
disease. Sin Nombre was their cousin and was uniquely adapted to survive in the
urinary systems of mice, Peromyscus maniculatus to be exact,
the white-footed deer mouse. Disturbing mouse nests or sweeping urine-laden
dust aerosolizes the virus and brings it into contact with sensitive lung
cells. To read the full Sin Nombre virus investigation story see CJ Peter's
book, Virus Hunters, chapter 1.
Curry Village is a camp comprised of canvas tent-cabins in
the valley of Yosemite. It is affordable and popular with families. Thus far
six cases and two deaths from SNV have been confirmed in visitors to the park. Four
were known to have stayed in Curry Village. Others are under investigation and
an alert was sent to state health departments because an estimated 10,000
people from across the nation stayed at Curry Village from June to August this
year.
Prevention begins with sealing your house to prevent mouse
invasion, a difficult task. Even here in the Big Apple the industrious little critters
routinely make there way into apartment buildings. Trapping (I use live, “green”
mouse traps) and good food hygiene are the next steps, like disposing of trash
in a receptacle that rodents can’t penetrate. That includes food in your home, using
thick plastic, metal or glass canisters to store food. Caution is advised when cleaning areas
of mouse habitation. Ensure proper ventilation, spray the area first with a
disinfectant, like dilute bleach. This will inactivate viruses and keep dust levels
down. Wearing personal protective equipment to include a mask, goggles and
gloves is also a good idea. See full CDC recommendations here: http://www.cdc.gov/rodents/cleaning/index.html
