如何祛除家里的病毒和细菌 新冠病毒仍是头号公敌 太多国家正朝着错误的方向前进

新冠病毒仍是头号公敌 太多国家正朝着错误的方向前进  

The coronavirus pandemic will get "worse and worse" if governments fail to take more decisive action
the World Health Organization (WHO) has warned.
Director general Dr Tedros Adhanom Ghebreyesus said "too many countries [were] headed in the wrong direction".
Cases were rising where proven measures were not adopted or followed
he added.
他补充说，在没有采取或遵循已证实有效措施的地方，病例正在增加。
The Americas are the current epicentre of the pandemic. The US has seen a rise in cases amid tensions beeen health experts and President Donald Trump.
The US
the worst affected country
has over 3.3 million confirmed cases and more than 135
000 deaths
according to Johns Hopkins University.
At a briefing in Geneva on Monday
Dr Tedros said "mixed messages from leaders" were undermining public trust in attempts to bring the pandemic under control.
"The virus remains public enemy number one
but the actions of many governments and people do not reflect this
" he said.
Dr Tedros said measures such as social distancing
hand washing
and wearing masks in appropriate situations needed to be taken seriously
warning that there would be "no return to the old normal for the foreseeable future".
"If the basics aren't followed
there is only one way this pandemic is going to go
" Dr Tedros said
adding: "It's going to get worse and worse and worse."
Dr Mike Ryan
the WHO's emergencies director
said the easing of some lockdown measures in the Americas and the opening up of some areas had led to "intense transmission".
Latin America has confirmed more than 145
000 coronavirus-related deaths
though the number is believed to be higher because of insufficient testing.
Half of the deaths were in Brazil
where President Jair Bolsonaro has opposed strict measures to curb the spread of the virus.
Dr Ryan said closing down large regions would have huge economic consequences
but that local lockdowns in specific places might be necessary to mitigate the spread of the virus.
He urged governments to implement clear and "strong" strategies
adding: "Citizens have to understand
and it has to be easy for them to ply."
"We need to learn to live with this virus
" Dr Ryan said
warning that expectations that the virus could be eradicated
or that an effective vaccine could be ready
within months were "unrealistic".
He said it was not yet known whether recovering from the coronavirus would lead to immunity
or
if it did
how long that immunity would last.
A separate study released on Monday by scientists at King's College London suggested that immunity to the virus may be short-lived.
Scientists at the college studied 96 people to understand how the body naturally fights off the virus by making antibodies
and how long these last in the weeks and months after recovery.
However
while almost all of those who participated had detectable antibodies that could neutralise and stop coronavirus
levels began to wane over the three months of the study.
At the WHO briefing
health experts also said there was evidence to suggest that children under the age of 10 were only very mildly affected by Covid-19
while those over 10 seemed to suffer similar mild symptoms to young adults.
To what extent children can transmit the virus
while it appears to be low
remains unknown.
