Ebola: The Facts

I've heard a lot of people talking about the Ebola outbreak in Africa, worrying about such an outbreak happening here in the United States.  My gut reaction is that we are basically safe due to our health care system and standard safety practices, but sometimes a gut reaction is wrong.  So I did some research as to what we know about Ebola.

In the beginning...

Ebola first appear in 1976 in two outbreaks:  one in Sudan and one in the Democratic Republic of the Congo next to the Ebola river, hence the name.  Scientists believe that local fruit bats are carriers of the virus, and that it jumped from the fruit bats to humans through careless handling of dead fruit bats or dead animals who were bitten by the fruit bats.

Transmission Vectors


Transmission vectors are the ways and methods which a virus uses to travel from one host to another.  Some viruses trigger coughing and sneezing, using the air as a transmission vector to travel.  The Ebola virus relies on bodily fluids to infect a new host.  These fluids include blood, saliva, sweat, semen, and other secretions.  In fact, a man may carry the virus in his semen for almost two months after recovering.

In layman's terms, you need direct contact an infected host's fluids to get the infection.  That means either touching an infected person, an infected animal, or an object that contains a fluid, such as sweaty sheets.

You CANNOT get the Ebola virus through:

  • Air
  • Water 
  • Casual contact (e.g. walking next to someone)
  • Food grown or legally purchased in the U.S.

The Danger

Why are we so worried about Ebola, unlike the common cold or a host of other viruses?  Because Ebola is almost certainly deadly for people who don't get any treatment, and averages about a 50% death rate for people who do get treatment.  Actually, the range is 20% - 90% for various outbreaks over the years.  Still, that means a person with Ebola in the hospital still has a 1 in 2 chance of dying.

Symptoms

The Ebola virus starts out like any other viral infection, first you get a fever with muscle aches.  It then ramps up to one or more of these possibilities:

  • Headache
  • Vomiting
  • Diarrhea
  • Stomach pain
  • Unexplained bleeding or bruising
  • Rash
  • Internal and external bleeding, e.g. bleeding gums or bloody stools
  • Symptoms of limited liver and kidney functions, such as swelling of the hands, feet, or legs; shortness of breath; weakness; confusion,...
  • Low platelet count, low white blood cell counts, and elevated liver enzymes in lab work
Symptoms appear anywhere between 2 and 21 days after exposure to the virus.  If a person remains symptom-free after 21 days, he does not have the Ebola virus.  Also, a person is not contagious until he develops symptoms.  

Why We Shouldn't Worry

Despite the fact that two nurses in Dallas contracted the Ebola virus, generally speaking it is not easy for a person to contract this disease due to the limited transmission vectors, unlike the 1908 flu which spread through the air.  Plus, a person needs to be showing symptoms to be contagious, unlike Fifths Disease where a person is contagious until symptoms appear.  

We already have procedures in place in all healthcare environments to eliminate contact with another person's bodily fluids.  These procedures began in the 1980s in response to the AIDS epidemic, and have continued since.

The real reason there is an Ebola outbreak in Africa lies in their handling of dead bodies and the deliberate denial of the problem by local governments.  It is tradition to wash a dead body to prepare it for burial.  Sadly, the washers are the ones who contract Ebola and then pass it on to other people.  Because the local governments deny any problem, people are unaware that a simple fever and muscle aches can turn into something much worse, leading people to ignore the first symptoms.

In the United States, we tend to err on the side of caution.  In most hospitals outside of Dallas, if a patient shows up in the E.R. after being in Africa with symptoms that might be Ebola, that person is immediately put into quarantine and watched.

So calm down and carry on.  The Ebola virus might be running rampant in Africa, but we are safe.

Hidden Game

Okay, no one likes getting the "Not Connected to the Internet" page.  So Google decided to make it a bit more fun in the latest version of Chrome Canary.

In earlier versions, they changed the notice to include a dinosaur.  I think it looks like a stylized tyrannosaurus rex.



The dinosaur represents the time before the Internet, aka the Age of Dinosaurs.  (I laugh saying this as I too predate the Internet.)

But here's where the fun comes in.  If you hit the space bar, the page turns into a basic side-scrolling game.  The dinosaur runs along, and you have to jump it over cactus, using the space bar to jump.  The game saves your high score, so you can play multiple times if you want, though everything vanishes when you log out.



Here's a screenshot of me playing the game.  It shows my high score - 416 - and my current score - 30.  The game starts at a good speed, but ramps up as your score gets higher.

By the way, Chrome Canary is the early release version.  Google releases new features and whatnot in Canary, and whatever works gets released in regular Chrome.  If you are interested in running Canary, you can download the software at http://www.google.com/intl/en/chrome/browser/canary.html.

Please Stop Stalking Your Children

Dear Parents,

How are you doing these days?  I know that you have a lot facing you every day, from work problems to what to make for dinner.  But there's something that we need to discuss.

It's your children.  I know, I know, you worry about them constantly, as you try to learn what they're doing 24/7.  Well, good news - you don't have to do that anymore.  In fact, you shouldn't do that.

As children grow up and turn into pre-teens and teenagers, you want to watch out and help them along the way.  But to do this, you need to know where the problems are.  You don't trust your kids to come to you with problems, so you spend lots of money and time doing it for them.  They should be grateful, right?

Wrong.  By putting apps on their cell phones that spy on them, reading their emails, reading their posts on social media, using a GPS on the car, you are telling them in no uncertain terms that you neither trust nor respect them.

Think about it before getting on the defense.  Your behaviors feel uncomfortable sometimes (or at least they should feel uncomfortable) because you are stalking your own kids.  Yes, I said it.  You are stalking your kids.

Look it up, if you don't believe me.  According to Merriam Webster dictionary, stalking is to pursue obsessively, to the point of harassment.

But you're not harassing your kids, right?

Wrong.  Having to justify every single action, email, and text is more than annoying, it's harassing.  Being asked why you drove an extra block to get home?  Also harassing.

I know that there are a lot of people trying to convince you to stalk your kids, because a lot of people are getting filthy rich by spreading this paranoia and fear.  Think about all the apps sold to parents each day, the GPS systems, the newer cell phones with special parental controls,...  All of these things cost money, so of course the people who sell them will try to tell you that you need to read all of Little Susie or Little John's emails and posts.  How else will you know?

I'll tell you.  Communication.  That's the big secret to getting along with teenagers, pre-teens, and the like.  Talk to your kids, but more importantly, listen to your kids.  Don't start jumping to conclusions, and don't interrupt them.  But none of this communication will occur as long as you show your kid disrespect.

Instead, respect their privacy.  No more reading emails, diaries, posts, or texts.  No more listening in on phone calls.  No more tracking them through either their cell phone or the car.  Trust your kid to do the right thing, even if that means calling for help after making a mistake.

No, you can't turn your kid into someone who never makes mistakes.  But you can be there, have their back when a mistake happens.

But only if they trust you enough to let you know.

So please stop stalking your kids.  In the end, they will thank you for your trust and respect.

Sincerely,
Kathryn
