#Covid19 so little is actually known in scientific terms about Covid19 in terms of the fatality rate, the virulence, the infectivity, why different infected people have such different outcomes, the level of virus to be taken in, immune response, what triggers extreme immune ...
Scientists are not sure that their epidemiological models accurately reflect the development of spread of virus. Serological testing, accurate, of the population is critical.
Therefore scientists and modellers are unable to predict the increase in the number of infections and are unable to predict the number of deaths. They are only able to say that infections will increase and human deaths will result as a consequent of relaxatiin but cannot quantify
The destiny of the virus is unknown. The probability of immunity is unknown. If there is immunity, the duration of immune is unknown. The lethality of the virus is unknown. There is no efficacious treatment protocol yet established.
All that is reliably known is that the virus is transmitted person to person and so, for now, in the absence of a preventative vaccine or an effective therapy, reducing person to person contact is the only prophylactic measure available in public health terms.
And so reducing or relaxing lockdown measures will increase infection rates by an inkown amount and increase deaths by an unknown rate. It will take 3 or 4 weeks to gauge the impact of relaxation measures but it will be too late for some by then.
