And Now, the Good News about Smallpox

That's been my point since the beginning of this talk about smallpox. It is such a virilant disease, it would spread to the third world so fast it would make the terrorists heads spin. The Muslim world would be most at risk because they have huge populations, lack of sanitation, lack of medical facilities etc.

We would recover. Some of us have had vaccinations, we live spread out, cities would be quickly quaranteed, there is enough vaccinations available to treat those exposed. However, the Muslim countries would probably end up losing half their population, and the remaining half would be horribly disfigured. If the terrorists use smallpox, they are condemning their own people and way of life to death.

[Excuse_Me]

Thanks for the "good" news. They stopped vaccinating by the time I came out of the chute.

Then you're not old enough to be a Senator...

[Victoria Delsoul]

According to U.S. Census Bureau data, about 40 percent of the U.S. population is 29 or younger, and having never received a smallpox immunization, up to 30 percent of that cohort would die if infected with the virus during a bioterrorist attack.

Gee, thanks Saber!

[TomB]

By the way, I wonder what you and the author of the SLATE article would consider an "acceptable" casualty rate? What if only 10% of Americans died? How about only 5%- would that be OK? At what projected case fatality rate should everyone just relax? (A 1% rate would mean the deaths of almost three MILLION Americans...)

You know, I have NO IDEA what you are taking about. If smallpox appears in the US, it is (another) act of war, and we should retaliate in kind (for weapon of mass destruction). Even if one person dies, it is still an attack, and should be treated as such. But that isn't what we are discussing in this thread. Why do you keep bringing it up?

I'm just tired of all the scare mongering going on around here lately, and I'm just trying to add some balance to the "we're all going to die" crap that some people are tying to spread.

There has been a lot of misinformation around here about smallpox, and it needs to be corrected.

If it makes you feel better to believe that smallpox, the ancient scourge of mankind, really isn't all THAT dangerous, then do so.

You know, garden variety infections were an "ancient scourge" also. That doesn't mean we are afraid of them now.

And you expect us to believe you are that young? Those stories might have worked on your ex-wife but...

As far as the disease itself, the most important thing to remember is that it is NOT contagious in its initial stages. Only after the appearance of the telltale rash, usually after 10 or 12 days, does the disease become contagious. However, once the rash does appear, the patient becomes very weak and is likely to be bedridden by that time. This means that containing the disease is much easier that you've been led to believe.

Easier if you are talking about ONE patient who is promptly placed in an isolation ward, and all attending nurses, physicians, etc., follow protocols EXACTLY and without any mistakes.

If you are talking about hundreds or thousands of cases happening simultaneously in one city, however, then keeping all patients completely isolated becomes extremely difficult. We simply don't have the isolation wards, equipment, training, etc. to do it.

You sure about that?

I've read that smallpox is contagious during incubation, prior to the manifestation of symptoms. There were also several smallpox threads on the subject last week, with comments from doctors, and none suggested that the virus wasn't contagious prior to the development of pustules.

I'm not an expert, but based on what very little I know, I would guess that there is probably at least a very narrow window of opportunity between the moment when the earliest symptoms develop and the earliest moment when the symptoms would be obvious enough to make smallpox a suspicion. In other words, during those first few hours when you start coming down with something, you usually don't know for sure whether it is just a cold, the flu, or something more serious. It is that time period when a contagious kid could infect dozens at school, maybe more dozens on the school bus, the rest of the family, then dozens more in the waiting room. All within the course of perhaps three or four hours.

[GailA]

I remember getting mine in school, I'm 53. My eldest who is 31 had it, but my youngest who is 19 of course did not get it. Hubby who is 54 also did not receive one.

[Stefan Stackhouse]

Another point, there was an outbreak of smallpox in New York City in 1947, in which a man arrived from Mexico sick with the diesase. The diagnosis of smallpox wasn't even made until two other infections had been identified. But despite the headstart, there were only 12 total cases.

We have the ability to keep a dangerous diesase like smallpox under control.

Sure we have the ability to keep a dangerous disease like smallpox under control -- when the vector consists initially of a single infected individual.

I can very easily imagine a technique by which terrorists could simultaneously infect thousands of children in dozens of cities this halloween. That presents a much more challenging scenario.

[WIladyconservative]

Anyone have James Herriot's number, because I don't know what cowpox looks like.

Sorry dear, James Herriot died in the 80's (but not of smallpox, of old age)!

[chantal7]

I wonder if it would be possible to protect our kids by some type of blood transfusion? I mean, if the antibodies to smallpox is still in our blood and the doctors could safely draw a bit of our blood and inject it into our kid's blood to give them a bit of immunity? It would be using the parents instead of a horse or other animal for the innoculation.

Kind of like when some of the African doctors drew blood from the few who survived the ebola outbreak a few years ago and transfused it to the last 8 who were suffering ebola and most probably going to die from the ebola. Those doctors went against other authorities to inject the blood of the survivors into those still suffering ebola and saved 7 out of the last 8 that had it. Including a beloved nurse at the hospital. She was one of those that lived because of those transfusions.

And I wonder if the antibodies are passed to the children who have been breastfed?

I believe (and I'll admit it if I'm found to be wrong) it behaves like chicken pox - incubation is several days to 2 weeks and then the pox show up. Once the pox show up is when one is contagious. That's why my pediatrician hustled me out of the waiting room and out the back door of the office when I brought my son in with this strange rash last year . . . .sure 'nuff - It was chicken pox (a year AFTER his chicken pox vaccination).

[Stefan Stackhouse]

If there's an outbreak in my area, she won't leave the house until the CDC has vaccinations on the ground, which will probably be within 48 hours of a confirmed case.

You are absolutely right! The only defense against smallpox, other than vaccination, is isolation. Think: Quarantine.

But, remember, you have to isolate EVERYONE in your household until the vaccinations are made available. The previously vaccinated members of the family could still bring the virus home on their clothing, etc. and infect your daughter. No work, no visitors, no mail, no new supplies (food, water). Nothing comes in from outside the home. No contact with the outside world whatsoever.

It would only be for a few days at most and the only sure way to keep your daughter safe.

I'm a nurse, with an unvaccinated son, and this is exactly what I intend to do if a smallpox outbreak occurs in my area.

Congratulations! You've figured it out. Most people have no idea WHY anyone would want to have a few days of food, water, etc. stored at home. A bunch of kooks, they tell us.

The big problem, however, is this: How are we going to know soon enough that there is a smallpox outbreak so that this can become a reliable strategy? The problem is that the public health authorities are unlikely to know for sure until quite a few people have already become infected, and there will be unidientified contageous people out there continuing to infect others even after they have made a firm diagnosis. There is also no certainty that the government is going to be quick to announce this. They will know that most people will be as underprepared as the government itself, and will be greatly concerned about mass panic. Also, while YOU will want to be hidden away out of infection's range, THEY will want you to be at work, preferably oblivious to the danger, at least until they have gotten their own ducks in a row (and their own and their own kids behinds vaccinated).

Actually, that is incorrect. According to the CDC:

Twelve to 14 days after infection, the patient typically becomes febrile and has severe aching pains and prostration. Some 2 to 3 days later, a papular rash develops over the face and spreads to the extremities). The rash soon becomes vesicular and later, pustular . The patient remains febrile throughout the evolution of the rash and customarily experiences considerable pain as the pustules grow and expand.

So there are initial symptoms which are likely to cause the person to become bedridden, BEFORE the rash appears. So there is no "window of opportunity".

[Sabertooth]

Keep in mind, Chicken Pox is not a true Pox virus, it's in the Herpes family.

Smallpox and cowpox are trey Poxes, and are in the Variola family of viruses.

The characteristics of Chicken Pox aren't necessarily going to be a good indicator of the characteristics of Smallpox.

Seeing as how smallpox has been eradicated, the appearance of even ONE case will let you know.

Historically, the rapidity of smallpox transmission throughout the population was generally slower than for such diseases as measles or chickenpox. Patients spread smallpox primarily to household members and friends; large outbreaks in schools, for example, were uncommon. This finding was accounted for in part by the fact that transmission of smallpox virus did not occur until onset of rash. By then, many patients had been confined to bed because of the high fever and malaise of the prodromal illness. Secondary cases were thus usually restricted to those who came into contact with patients, usually in the household or hospital.

Confined to bed where? At home.
By who? By Physicians who routinely made house calls.
House call? What's that??????

If there is a smallpox attack, every single victime is going to be taken to a clinic or emergency room. And large numbers of people who are already sick or infirm -- and thus more vulnerable -- will inevitably be infected. Many more than would have been typical in those earlier days.

Aren't you glad our new way of doing medicine is so much more "efficient?"

[ecru]

I agree with you, also, considering the medical advancements with anti-virals, and care, I think alot of people who did have it would be saved. If the rate of death was 30% how many years ago, it might be different now, especially now that we are so aware of the possibility of it happening and intervention.
If these jerks even have it, and do spread it out to a large amount of people, I don't worry as much about the actual disease, but the reaction of panic and fear from people, and the way the media will try to put the whole durn country into freak out mode.
You can bet the minute someone walks into an emergency ward covered in pustules, severe measures will be taken to contain and vaccinate those at risk. (cross my fingers)
It's the third world countries that will suffer the most.

[TomB]

Confined to bed where? At home.

Of course. And the most severe cases can be treated at a quarantine ward of a hospital.

If there is a smallpox attack, every single victime is going to be taken to a clinic or emergency room. And large numbers of people who are already sick or infirm -- and thus more vulnerable -- will inevitably be infected.

Please explain ow this would happen, since you are sick for 2 or 3 days BEFORE YOU ARE CONTAGIOUS?

You are trying to scare people. Fortunately, you aren't doing a very good job of it.
