Dödligt virus från Kina orsakar panik (SARS-CoV-2, COVID-19)

Och med tanke på vad vi ser som utdragna förlopp och andra märkliga fenomen med antikroppar och med frånvaro av sådana bör man nog vara försiktig öht att dra några slutsatser.

Det finns andra virus som människan har svårt att bli av med. Man behöver inte nödvändigtvis gå till HIV. Du har hepatit-c där man i de flesta fall behöver kraftfulla antivirala för att bli av med det trots att man är full med antikroppar. Så länge man har infektionen är man höggradigt smittsam.

On 2 February, a man in the Philippines became the first person outside China to die of Covid-19.
At this point, there were no reported cases in New Zealand, but the next day, the country began banning entry to any foreigner coming from or via China. Any New Zealander returning from China had to isolate for 14 days.
As the virus spread globally, a flight ban was also extended to Iran - the origin of New Zealand's first case - and restrictions placed on anyone arriving from South Korea, northern Italy, or who was showing symptoms.
As of midnight on 16 March, everybody - including New Zealanders - had to go into self-isolation on arrival in the country, unless they were coming from the largely unaffected Pacific island nations.
Prime Minister Jacinda Ardern said these were the strictest regulations in the world, for which she would "make no apologies".
Then, a few days later, Ms Ardern took the unprecedented step of closing the borders entirely to almost all non-citizens or residents.
"Doing this early on with only over a few thousand cases [worldwide] at the time allowed them to basically stop the influx and stop the community transmission," Prof Martin Berka, an economist at the country's Massey University, told the BBC.

But by mid-March it was clear the virus could not be controlled with the standard pandemic flu action plan, one of New Zealand's top epidemiologists, Prof Michael Baker, told the BBC.
A World Health Organization (WHO) report on the success of Wuhan's lockdown in late January made it clear the New Zealand approach should be to "throw everything at it at the start" and aim for total elimination, said Prof Baker.
"We had to move away from the normal level of scientific certainty and say well, on balance of evidence, we know this has worked in China."
In late March, to prepare the public for a rapidly changing situation, New Zealand introduced a new four-stage alert system. Based on existing wildfire alerts, it would clearly indicate the current risk and the necessary social distancing measures.
Prof Baker says officials did an "absolutely remarkable job" of implementing New Zealand's lockdown. Even at its peak, New Zealand had only 89 cases a day.
"They really engaged the minds and hearts of the population into doing the unthinkable, of saying 'go home and stay there for the best part of six weeks'," he said.
The time bought by the lockdown was used to finesse an extensive testing and contact tracing operation. New Zealand can now carry out 10,000 tests a day and when a case is confirmed, contact tracers get to work alerting anyone they had close interactions with and telling them to isolate.
The WHO has praised New Zealand for acting quickly, holding it as an example to other countries.
