Covid-19 – stealth virus?

Apologies, I had a completely different post in mind for today, but this update is really important. When Covid-19 first started to spread, we were told that people might be a little infectious a day or two before symptoms developed, but they shed most of the virus [i.e. infected others] after the symptoms became obvious. It seems the advice was wrong.

New evidence suggests that the reason Covid-19 is spreading so widely across the world is because most of those infected are asymptomatic – i.e. have no symptoms at all, not even mild ones. Effectively, this makes Covid-19 a stealth virus, similar to HIV [part of the reason HIV spread as far as it did was because victims did not know they had it].

Dr John Campbell does a good job of explaining the evidence for the new findings and highlights why testing is now more vital than ever.

Adding to these sources is the data from Iceland. Because Iceland has a very small population and very good health care, they did a lot of testing per capita. What they found was that roughly 50% of those testing positive for Covid-19 were asymptomatic.

So far, most countries have only tested those people who are already symptomatic – i.e. to confirm the presence of the virus – or those who may have come in contact with infected people. There has been no testing of the population in general. Without general testing, we cannot know who is infected and who isn’t. More importantly, we cannot know who is spreading the infection, and who isn’t.

Lockdowns are a shotgun approach that works because it effectively assumes that everyone is a spreader. But this is only a short term solution. We cannot come out of lockdown until we know who the spreaders really are. That means testing on a grand scale.

If you are on other forms of social media, please pass this information on as it could influence our leaders to get serious about testing.
