thats a mutation .... crumbs and you still have partial immunity from repeated infections ..
The virus variations
Unfortunately for us, there are lots of different viruses which can all cause very similar common cold-like symptoms. These include viruses like parainfluenza virus, adenovirus and rhinovirus, all of which cause things like sneezing, headaches, coughs and a runny nose.
However, each of these viruses also have subcategories, called serotypes, or strains. For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can’t get ill from the same virus serotype right after getting better, due to the fact that you’ll have developed antibodies which help to protect your immune system for a little while. The not so good news is that you can get another cold from a different virus, or a different virus strain.
Keep in mind that it’s rare that two virus serotypes that cause the common cold will be in circulation at the same time of year in one location. What this means is that if you get sick and then your partner does just after, you’ve probably both suffered due to the same dominant strain of virus – which you have now developed antibodies against. There are also some occasions where the antibodies you’ve developed against one strain will offer some protection against other closely related strains, but this is not guaranteed.
