i keep seeing conflicting arguments about covid being similar to some flus or different to others
there was a lady a few weeks back who works in virology and shared some really insightful information into how viruses actually exist and attach to the body and replicate etc
i was wondering if anyone with similar background would mind explaining what the similarities and differences with other viruses are?
obviously the symptoms can be different and the severity but i was more particularly thinking about methods and rates of transmission
for example are the methods and rates of transmission similar or different for flu and covid , is it only vaccines and herd immunity that drive any existing current differences, are people born with inherited immunity to some viruses from their parents herd immunity?
one of the reasons i ask is i have never had a flu vaccine and believe i have only had the flu once in my life (over my 30th  ) so wonder why it took so long for me to get it and why the other strains seem to have passed me by
this isn't me trying to say one if more dangerous than the other or any conspiracy about how at risk people really are ... more just intrigued as to the science behind it |

Your immune system is typically stronger when you are younger. As you age, it weakens and you are more susceptible to flu. This is why a flu vaccine is offered to older people. One of the issues is that there isn’t one flu, so vaccine’s may not work. Most people who say they have flu actually had a heavy cold (especially if they were men), unless they were unlucky or over 50.
Covid 19 is a more lethal flu than normal.
Hope this helps. |

There are some great podcasts on it which are in layman terms, have a look on YouTube, or if you can understand scientific papers, there are some very interesting german ones that are proposed for peer reading |

Influenza typically when it causes problems triggers pneumonia or raises an issue with a underlying health issues..
This Covid19 can cause this, can act like a wider infection cause issues with the bodies ability to put oxygen into other organs..it can cause multi organ failure
It's fill range of problem and an attack on the whole body. |

For me personally the cough was the only difference to all the flu I have suffered through previously.
Maybe having had my annual flu jab or the pneumonia jab prevented me having a different reaction/experience.
Had it not been for all the media hype I would have simply believed we'd all got the flu  I took the exact same measures (calpol/paracetamol/fluids) so it was literally that annoying cough, and that came late to the party and wouldn't just go. |

So did you test positive for covid 19? and is it worth worrying about as much as the media say? |

It's not people that have survived it you want to ask. You have seen the numbers of deaths haven't you? |

Try the free OU course on Infection and immunity. I gives a guide of 12 hours but I'm sure you'll whizz through it. Just be aware the data maybe dated dependent upon year of publishing.
I state that warning as I've just used a course as a revision tool. It was written in 2004. |

We can contract a virus, such as 1 of the many flu viruses, and not be particularly aware, if at all, that we have it. We may have felt a little, nothing or thought we were groggy with a cold etc.
The volume of others who have had it or a vaccine, helps to drive herd immunity, making it less prevalent in our vicinity.
Comparisons are useful, particularly if they help us to understand something abstract or unusual. Colds, flu, and covid19 are similar in their modes of transmission and some symptoms may be similar too. This is a new disease obviously, so we're learning. How infectious it is depends on things about it as well as about us and our behaviour. You can research how long these individually survive on different surfaces, for example, which affects how many more or fewer people may physically contact them. 1 of the biggest things is that not anyone had any immunity and it took some time to get people to modify their behaviour to reduce risks of passing it on.
Another key difference is the delay between picking it up and when first symptoms may appear but you are infectious. This is typically much longer with covid19 - towards a week, compared to perhaps just over a day with flu. Covid19 also seems to have a very high level of people who have no symptoms and who are thus less likely to be home feeling sick, keeping others at bay.
The period it's infectious to others is also fairly long, perhaps almost for twice as long as the others. You can look up the individual virus periods to do this.
We're still only developing our knowledge of this virus though and it will improve. |

It is all down to the outer proteins and how they trick the bodies cells to think they should be inside once there they trick the nucleous to replicate the dna or in this case the rna the messenger part of the genetic sequence The problem is this process is imprecise because it is not a correct message so it mutates often |

"Its a new strain of flu
But in time the biggest killer going to be Anti biotic not working
Due to the amount they pump into live stock"
How many times do people need to be told it is NOT an influenza virus. It is like it in the matter that it affects the respiratory system. |
