The questions about the credibility and transmission of the virus are :
1. Kids ( under 12 ) who don't have a fully developed immune system are being said as not so vulnerable to the virus. If there's some virus kids can be infected more than adults and kids can spread it much faster than adults.
2. Covid19 may be there but is there any single evidence where someone died without covid19 testing. If there's some thing it's all in the test kit ( not on every kit though ).
While it is true that kids are more susceptible to infections, the thing here is that Covid-19 in extreme cases causes a runaway immune system reaction, known as a cytokine storm. People who are young have less chances of this happening as their immune systems work properly. Those who are older or have weakened immune system and/or take medications for diabetes, etc are more at risk because their immune system doesn't cope efficiently and often overreacts. At least, that's what I've understood.
As for people dying without testing positive for Covid-19, there are countless such cases. I remember reading an article about people who wanted to be tested but were not tested because they needed a doctor's approval, and then they died; I think this happened in Mumbai. There are many such cases.
3. Confusing and contradictory information from various scientists/Doctors/Virologist from time to time.
That is a problem, with various doctors/organizations saying this and that. On top of that, social media spreads all sorts of lies. During the beginning of this epidemic, I remember watching a video of a doctor who said that if you can hold your breath for a minute or so, you are not infected, but later I learned that the WHO had clarified that you could be infected even if you can hold your breath, probably because you are not affected severely. If you were, you would probably know and wouldn't need to hold your breath to check.
This is a new disease and it will take time for proper information to come out, so doctors will change their stance and treatment methods. We on our part, just have to be careful, as much as possible. I would also say wait for the vaccine, but even that is something you cannot trust at present, since they are being prepared in a hurry. Vaccines take a lot of time to develop and have to be tested properly before being given to people. See this about the dengue vaccine in the Philippines:
*en.wikipedia.org/wiki/Dengvaxia_controversy
The article itself is not clear on whether the vaccine caused the problem or not, but once you hear such a thing, you would obviously stay away from it. But doing that comes with its own set of problems, which is what happened later in the Philippines, causing a surge in other infectious diseases.
I, for one, will wait till the very end, after all issues with the vaccine(s) have come out and been resolved, before I take a shot.
If the virus was that much contagious then the infection rate would be like a hostile projectile in a country like ours.
Now this is something that everyone is wondering about, why we have comparatively lower deaths compared to other countries. Earlier they said the hot weather is helpful, but I think that has been disproved, not sure though. Then there's this thing that Indians have earlier got the BCG vaccine which is in some way helpful.
The 1918 Spanish Flu had wreaked havoc in our country, compared to which Covid-19 seems pretty mild. The Spanish Flu was dangerous for the same reason Covid-19 is - the cytokine storm.
What really is unbelievable is China's death rate - 4634. Anyone has any info on what their actual numbers are?
