Scientists still working to try to understand what the coronavirus actually is.
The main effect is in breathing – feels like holding breath too long or being in high altitude on mountain. But body often is not aware of lack of oxygen and just carries on – “happy”.
Means do not get breathing machine fast enough. Also it affects kidneys and so, many in hospital need special treatment with extra machines.
People who are overweight are affected much more. Boris Johnson was overweight so his virus was worse.
Big question is why problem affects London and New York…. Advanced countries … but less for India and Africa, in their big cities. Scientists puzzled.
They say birthday parties and weddings are the worst for spreading the virus as close contact and one person can infect 10 people.
You know about the R0, ?? pronounced “R naught,” It is the reproduction number. R0 tells you the average number of people who will contract a disease from one person with that disease. In UK, we have R3 meaning 3 people catch the virus in contact with one person. Social distancing is the way Government has to get the figure to less than R1, so then the virus can be almost stopped.
