A senior World Health Organization expert has said that there were some indications that COVID-19 coronavirus disease transmission outside China might not be the tip of the “iceberg” that had been feared. 

Dr Michael Ryan, the World Health Organization’s (WHO) Health Emergencies Programme chief, said, that routine winter testing of patients with chest ailments in hospitals in China, Singapore and Hong Kong had not indicated widespread COVID-19 transmission.

“In emergency rooms and as part of normal winter respiratory disease surveillance, they’ve been actively testing thousands of samples that are not suspect cases of COVID,” he said, adding that at the moment, experts are just not seeing COVID activity amongst those samples, an indication that the iceberg may not be that great. 

As of 4 pm on Thursday, there were 46,550 infections from COVID-19, the overwhelming majority in China, WHO reported. Of the 1,369 deaths from the coronavirus to date, all but two have been in China. Outside China, there have been 447 cases from 24 countries and two deaths; one in the Philippines and another in Japan. 

The biggest cluster outside China is on the Diamond Princess cruise ship, which is in quarantine in Yokohama port, Japan. To date, 218 passengers on board have tested positive for COVID-19, Dr Ryan said.

Other cruise ships in the South China Sea continues to be affected by fears that they may be carrying the virus.   Nonetheless, fears that only a fraction of cases was being detected were “as valid as speculations in the other direction”, Dr Ryan insisted, before adding that no specific treatments existed for patients, beyond standard antivirals used for the previous coronavirus outbreaks, such as during the SARS epidemic in 2003. 

Dr Ryan explained Vaccines and new drugs would take a long time and require a huge investment of hundreds of millions of dollars, D, before urging the public and private investment to spread the risk. 

Dr Ryan said that the latest data showing a jump in infections reflects a change in how cases are being diagnosed and reported by Chinese authorities. 

From now on in Hubei province only, trained medical professionals are authorized to classify a suspected case of COVID-19 as a clinically diagnosed case based on chest imaging, rather than having to have a laboratory confirmation, the WHO official said. 

“This allows clinicians to move and report cases more quickly, not having to wait for lab confirmation, which means that people get clinical care more quickly, and also allows public health responses in terms of contact tracing and other important public health measures to be initiated.”  

Confirmation of the latest infection tally comes after WHO Director-General Tedros Adhanom Ghebreyesus welcomed the Cambodian authorities’ decision to allow a cruise ship to dock there. It had been reportedly denied entry elsewhere because of fears that its passengers may have contracted the virus.  

“People with mild respiratory or gastrointestinal symptoms are being treated on the Westerdam by cruise doctors and 20 of those are being tested for COVID19,” the WHO chief tweeted earlier in the day. He noted that the samples have been transported to laboratories via helicopter at Sihanoukville Seaport and that all passengers and crew remain on board in quarantine.  

Three cruise ships had either experienced delayed port clearance or been denied entry to ports. Often, said the WHO chief, without an evidence-based risk assessment.  

“WHO stands ready to provide any additional support to the Government, especially in building preparedness capacities for COVID19,” he added, before noting that he was “deeply grateful to the Government, particularly Prime Minister Hun Sen”, for their gesture. 

In an earlier tweet, he also thanked Germany’s health authorities after Health Minister Jens Spahn called for more support from fellow European Union members to fight the epidemic. To date, Germany has reportedly identified 16 cases of COVID-19.  

“I fully agree that we need to work as one to keep the world safe from this virus,” WHO chief tweeted.
