THMG192 – Ebola 2 and Leaky Faucets


We finish up the topic of Ebola and talk about mutations and spill over. Then we have some spare time to take a quick peek on some detective work done by a listener on a wet Carbon Monoxide alarm…Hmmm

  1. So last week we talked about ebola a bit
    1. Its history, how it’s transmitted and how to protect ourselves from it.
  2. For those of you who were not aware, it’s July 2019 and there is currently an outbreak happening now started in Aug 2018. 
    1. As of July 2019, it is the 2nd largest outbreak. However, we, not even a year into it and the West Africa outbreak lasted for 2 years.
    2. This outbreak is in the northeastern area of the Democratic Republic of Congo
  3. There is a growing sense that this is going to be a far worse outbreak before and fear has lead to the notion that the virus has changed.
    1. So is the natural evolutionary changes that take place from generation to another responsible for the massive spread?.
    2. Do virus actually change?
      1. Yup just like we do! Sorry creationist but it’s real. Virus-like everything else mutates over time. 
        1. Every time a virus reproduces there never an exact copy made. (just like in people). 
      2. So is this what is driving the current outbreak.
        1. Viruses are constantly being genetically mapped. Each person that gets sick is just a little different from the person they got sick from. This can create a linkage that can be traced back to patient zero. Like branches on a family tree.
          1. We know that West Africa was linked or related to central Africa which originally spilled over from Guinea.
          2. Libera had multiple types of family trees which means that it was not a single source but came from multiple isolated crossovers.
          3. Some of the changes that they have seen are changes in the amino acid sequence of proteins that they encode for.
          4. It does not seem like these current changes are helping the virus in fact since the spillover and 2014 outbreak a lot of the mutations that were made have died out suggesting that they were actually “bad” or gave a negative benefit towards reproduction.
        2. Explain adapt to humans
        3. There are some who still express caution.
          1. There have been a few changes that have been noted in the glycoprotein. These changes would or could lead to a decrease in how the human immune system reacts to the virus.
          2. But so far the overall answer is no
    3. So what has changed?
      1. Again the answer to the spread of this lies within the social fabric of the people.
        1. The people of these countries are very transient
          1. This accounts for the pop out outbreaks in various areas
        2. They do not trust foreigners
          1. So when people started to get sick they never sought out help.
          2. Families members died at home before authorities even knew there were people sick
          3. As the family was both near them and unwilling to follow the advice of the outside world it allowed a vast number of people to be infected before attempts to control the outbreak were even put into place.
