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


As scenic vacations go, Yosemite is spectacularly breathtaking. Whether you are viewing the awesome rock formations from an overlook or standing in the valley staring up at a waterfall. In the world of hantaviruses, Sin Nombre virus (SNV) is equally breathtaking. Literally. In the spring of 1993, in the Four Corners area of the US, the Sin Nombre virus killed two young, accomplished long distance runners. They died of sudden respiratory failure and the only clue was that the two victims were engaged to be married. A week later another couple became seriously ill with the same air gasping symptoms. One was a relative of the very first case.  The damage to the victim's lungs looked like they had inhaled World War I nerve gas. When investigators visited the home of the first two cases they found no obvious source, but noted that they place was heavily infested with rodents. El Nino’s rains resulted in a bumper crop of pine nuts, a staple for the white-footed deer mouse and their numbers had doubled since the previous year.


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
