Three more European countries reported their first COVID-19 cases today, mostly linked to Italy's outbreak, and more newly affected Middle East countries confirmed more illnesses linked to an outbreak in Iran.
In other developments regarding the novel coronavirus, the leader of the World Health Organization (WHO) joint mission to China gave a detailed report on the group's findings in China, and case numbers grew in other affected Asian countries, mainly in South Korea and Japan.
WHO joint mission observations
The WHO-led international joint mission wrapped up its visit to China yesterday, and Bruce Aylward, MD, MPH, who led the 25-member group, today briefed reporters on the team's experiences and findings. He said that, without a drug or vaccine available to battle the new virus, the country used standard public health tools such as case finding and contact tracing with rigor and innovation "on a scale that we have never seen in history."
Though Wuhan and Hubei province are the epicenter, the outbreak evolved differently as the virus spread to other provinces, and though the central government enforced rules, provincial health officials had the flexibility they needed to tailor the response to their situations.
The team also observed how China "repurposed the machinery of government" to battle the outbreak and used big data tools, including artificial intelligence, to manage a massive amount of information, such as contact tracing.
Aylward also said the team observed an agile, science-driven response, during which the government updated its clinical guidance six times as it learned more about the virus and illness.
China's stringent measures, such as sealing off towns and ordering people to stay in their homes, changed the course of the outbreak, with a decline that is now occurring sooner than expected, Aylward said. Team members had multiple ways of getting a sense of the decline, such as talking to doctors in Wuhan who spoke of open hospital beds and no more waiting lines for testing at fever clinics.
Because of the decline in cases, Chinese researchers report slower-than-expected enrollment of patients in drug treatment trials. China today reported 508 new cases, up from 409 reported yesterday, for a total of 77,658. The death toll is at 2,663, and there are 9,126 serious cases, according the National Health Commission.
Aylward urged countries that are bracing for outbreaks to shift their mindset. "The world is not ready, but can get ready fast," he said, emphasizing that countries can indeed affect the course of the disease with aggressive and tough programs, noting that key steps should include planning for a heavy demand on hospitals and respiratory support, such as ventilators, staffing for contact tracing, and getting the public on board.
A big question that still remains unanswered is how many mild cases go undetected, a metric that is key for getting a better handle on the disease's severity and fatality rate. Aylward said the group saw bits of information, such as testing of samples from China's flu surveillance system and testing of convenience samples, that hint the number of milder cases may not be great. However, he said that over the last few days China approved two serology tests, which will help answer the question.
He said though asymptomatic transmission might play some role, household exposure seems to be the main driver of the outbreak. And he noted that many health workers who got sick were exposed in the community.
Regarding the clinical spectrum, Aylward said about 88% of patients remember having a fever and 68% had a dry cough. Only about 12% had a runny nose, hinting that COVID-19 might not have much upper respiratory involvement. Some patients reported a prodrome that consisted of fatigue, muscle pain, and a vague feeling of being unwell.
In those who have symptoms, 80% have mild disease, 13% have severe illness, and 6% are critically ill, the group found.
When pressed on whether countries outside China—especially those without strong central governments—could replicate China's experience, Aylward said countries can be masters of their own fate. "Can that be replicated? Why not?"
