Laika

November 3, 1957

She was a mongrel female. Small, docile. It’s why she was chosen. Besides, the space suit was designed for females. They called her Little Curley, Little Bug, Little Lemon, Muttkin, but the name that stuck was Laika.

The training was rugged. Laika was placed in tiny containers for many days. She deteroriated; restless, apathetic. She stopped defecating so they gave laxatives which didn’t work. Even mongrels know you don’t shit where you eat. 

The centrifuges were the worst, noisy, nauseating. How did the humans know? The sensors they surgically implanted in Laika’s body. Laika’s heart rate would go off the chart and her blood pressure would shoot dangerously high. The humans persisted. They were on a mission.

Dr. Yazdovsky took her to play with his children. “I wanted to do something nice for her, she had so little time to live.”

Laika was placed in the capsule 3 days before launch. Her fur was painted with a cold, weak alcohol solution and iodine was painted over her sensors. The temperature was below freezing so they blew warm air toward her and human staff monitored her. One female doctor broke the rules and gave her a food treat. Before closing the hatch, they kissed her nose and wished her ‘bon voyage’ knowing that she would not survive the flight.

At peak acceleration, Laika’s breathing rate quadrupled and heart rate tripled. She was at weightlessness for 3 hours before her pulse came back down to her pre-launch rate. But the rocket system failed. Block A core did not separate from the capsule and that kept the thermal control system from operating. Capsule temperature soared high. By third orbit, Laika’s vital signs had stopped.

After 2570 orbits, Sputnik 2—including Laika’s remains—disintegrated during re-entry on 14 April 1958.

She was the first living, earth-born creature in space.

Pediatric ICU On Call

September 29, 2020

On call, ICU, Halloween 2010

Halloween. 10pm. 

Fluorescent lights scorch my sleep-deprived, red-rimmed eyes. Thirty-seven hours in the intensive care unit, weary, frazzled, sapped.

I walk by a Wizard of Oz scarecrow feeding applesauce to a tiny trauma toddler; I hear a Walking Dead wailing into the desk phone. 

Rhythmic shushing of breathing machines ghost through the glass walls, staccato beats of heart monitors shadow my steps. 

Double doors whoosh open and the waiting room gapes. 

Parents reach toward me —pale, angled faces with monstrous black eyes asking questions I cannot answer, lips parted in silent supplication. I mumble banality and the apparitions, half-satisfied, skitter to the edges of the room. 

I slip into the elevator and as it slides to the parking lot…

I realize I’ve missed the trick or treaters at home.

Crows

Autumn crows

WHO INVENTED DEATH AND CROWS AND IS THERE ANYTHING WE CAN DO TO CALM THE NOISY CLATTER OF DESTRUCTION? 

What a hard year. We’re all dying, even that crow talking loud and kicking up snow. 

Maybe he thinks he can head it off with a little noise, a fight. Or his silver-colored soul just wants some attention in his feathered suit. 

That’s what I Iike about crows. Decorum has another shape. They aren’t afraid to argue about the inarguable. 

We fly into the body and we fly out, changed by the sun, by crows who manipulate the borders of reason. 

Of course it’s not that easy, and I’m circumventing the matter as I marvel at the sun sleeping in the snow— 

the talk of crows getting in the way of poetry. I have a question for my soul, a creature who has little patience with crows—and less with snow. 

This question grows new leaves with each hard rain yet bends with grief at loss in the cold. 

This morning the question gleams with particles of the sun. There’s crying, there’s laughter. 

What do you make of it?

The Left Undone

LAUDAMUS

Gregory Loselle

So let us praise the incomplete,

the half-made-up, the left undone,

what’s underbaked, what’s scarce begun,

the set-aside, not-yet-concrete.

Let’s laud what’s left unsaid or dropped,

the barely finished, still to come,

to be announced, to be revealed,

still-in-production, uncongealed—

and praise, for all that, what’s to do

and what’s ahead: the yet-unplanned,

the things we’ve always said we’d do

and what we never thought we would,

and what we never thought we could—

ignoring what we knew we should

and didn’t, never found the time

and left aside, what we omitted.

Here’s to the things that didn’t fit,

that made no sense, that didn’t rhyme

or quite served the meter, what

we cast away, failed to commit.

So praise the ones who let things lie,

not bringing to completion all

that seemed so necessary once,

and proved irrelevant in time.

It Is What It Is

It Is What It Is

Before one even begins a discussion on infectious disease and public health, I think it is important to define the pertinent terms based upon generally accepted epidemiological principles. When I refer to an epidemic, I’m referring to the rapid spread of a disease to a large number of people in a given population within a short period of time. The disease may or may not be normally expected in the population in that area. An outbreak is also a rapid spread of disease to a large number of people but is frequently used when referring to a more limited geographic area than that used for an epidemic. A cluster is an aggregation of cases grouped in place and time that are suspected to be greater than the number expected, even if the expected number is not precisely known. A pandemic is an epidemic that has spread over multiple countries, regions or continents. It can be thought of as a traveling epidemic—add a P to epidemic for a passport {smile}. In fact, a useful way of differentiating these terms is to think in terms of the spread of a communicable agent: A cluster is initially observed, then it becomes an outbreak, which then becomes an epidemic which then becomes a pandemic. 


Sporadic refers to a disease that occurs infrequently and irregularly, such as tetanus or rabies. Endemic refers to the constant presence of an infectious agent in a population within a geographic area, such as chickenpox in the United States or Hepatitis B worldwide. Hyperendemic refers to persistent, high levels of disease occurrence such as malaria in Africa or dengue in Brazil or Papua New Guinea. An interesting observation is that diseases such as tetanus or rabies have never been known to reach epidemic status and therefore remain sporadic, whereas communicable agents that have reached epidemic or pandemic levels frequently then become endemic to human population. Seasonal influenza and small pox are examples of the latter and fortunately can be ameliorated with vaccine.


Covid-19 has killed 700,000 humans globally, 160,000 Americans. It was classified officially as a pandemic in 2019, becoming the approximate 17th pandemic in known human history. The Influenza pandemic of 1918 is frequently referenced for comparison purposes to the current Covid-19 pandemic. And, although actual numbers are subject to all the caveats inherent in data collection, the number of deaths attributed to the 1918 influenza pandemic (approximately 20-50 million worldwide) may in fact be surpassed by the on-going HIV/AIDS pandemic which has killed approximately 40 million humans and continues to kill at a rate of approximately 1-2 million annually. 



In the past 2500 years, humanity has experienced 250 epidemics, including pandemics, that have killed billions of human beings. I am referring to diseases caused by a communicable agent, such as a virus or a bacteria, and not to the presence of widespread, non-communicable diseases such as cancer or heart disease that also take a mortality bite on the human life-span. The transmissible agents most responsible for the highest death toll have been Yersinia Pestis, Variola major and Variola minor, Influenza A and B, and Measles, causing Bubonic Plague, Smallpox, Influenza, and Measles respectively.

Without a doubt, the Bubonic Plague ranks as one of the greatest killers of all time and constitutes 55 of the known 250 epidemics. The earliest known instance was the Plague of Justinian, a year long reign of terror in the 6th century which is thought to have killed half the population of Europe and, at its height, killed an estimated 5000 people per day in the city of Constantinople. Since that time, Yersinia Pestis continues to murder human beings even today with hundreds dying from it in Madagascar in 2014.

Smallpox, possibly the etiologic agent for the Antonine Plague that swept through the Roman Empire in 165 AD, accounts for 25 of the 250 epidemics with a death toll of approximately 16 million. Smallpox is an outstanding example of humans working together to eradicate a disease, successfully achieving that goal in 1980. The last known case of smallpox occurred in an outbreak in the United Kingdom in 1978 when Janet Parker, a medical photographer, contracted the disease and died. The source of her infection was traced to the smallpox virus grown for research purposes at the Medical School laboratory. Although the World Health Organization recommended destruction of the virus in 1986, resistance from the United States and Russia prompted instead temporary retention of virus stocks for specific research purposes. It is another, very long discussion on whether the continued presence of viable virus serves an essential public health purpose or a possible threat to humanity.

Influenza accounts for 20 of the 250 known epidemics in human history with the 1918 pandemic causing approximately 20-50 million global deaths. The death toll, however, like HIV/AIDS, continues to rise every year with seasonal flu deaths estimated at 60,000 annually. 

The other frequently occurring pathogens implicated in our history of epidemics include cholera, measles, typhoid fever, yellow fever, malaria among other pathogens that have occurred less frequently but still with devastating fatality rates, such as Ebola. The Zika, SARS, MERS epidemics are notorious for being new kids on the block of human epidemics. An etiologic agent that I am watching closely (as a retired member of the medical community so strictly as an interested observer) is the increasing frequency of epidemics attributed to dengue fever—16 epidemics in a variety of countries in the last 20 years.



It should be noted that in the last 10 years alone humanity has seen 20 epidemics occurring all over the world and involving the old standbys, such as cholera, measles, and influenza, but less well known agents such as Nipah, Japanese Encephalitis, and Chikungunya. This year alone, measles killed over 8000 souls in the Democratic Republic of the Congo, New Zealand, the Philippines, and Samoa while Dengue fever has killed approximately 4000 in Asia-Pacific and Latin America. Those epidemics should be included with the on-going Covid-19 pandemic with a death toll of 700,000 and counting.

I can only say to those who think of the Covid-19 pandemic as a ‘scourge’ that came out of ‘nowhere’ and as ‘something the world has not seen for a long, long time’—You. Haven’t. Been. Paying. Attention!
