Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 38 to 45.
The World Health Organization on Wednesday declared the rapidly spreading coronavirus outbreak a pandemic. Director-General Tedros Adhanom Ghebreyesus said that “We expect to see the number of cases, the number of deaths, and the number of affected countries climb even higher.”
WHO officials had said earlier they were hesitant to call the outbreak a pandemic in case it led governments and individuals to give up the fight. On Wednesday, they stressed that fundamental public health interventions can still limit the spread of the virus and drive down cases even where it was transmitting widely, as the work of authorities and communities in China, Singapore, and South Korea has shown.
The virus, which probably originated in bats but passed to people via an as yet unrecognized intermediary animal species, is believed to have started infecting people in Wuhan, China, in late November or early December. Since then the virus has raced around the globe. South Korea, which has reported nearly 8,000 cases, also appears poised to bring its outbreak under control with aggressive measures and widespread testing. But other countries have struggled to follow the leads of China and South Korea — a reality that has frustrated WHO officials who have exhorted the world to do everything possible to end transmission of the virus. Tedros used the fact that 90% of the cumulative cases have been reported in just four countries as evidence that the rest of the world still had time to prevent an explosion of cases with action.
WHO officials also stressed that countries should be implementing a strategic combination two types of measures. One involves trying to detect and stop known chains of transmission by isolating cases and following and potentially quarantining their contacts. The other involves community-level steps like social distancing and comes into play when the virus is spreading more broadly and transmission chains can’t be tracked. Mike Ryan, the head of the WHO’s emergency program, said that the public health interventions might not have straightforward effect, but to slow the spread of the virus. People with severe cases can require long periods of critical care and strain the resources of hospitals. He said he was worried about “the case load, the demand on the health workers, the dangers that come with fatigue, and potentially shortages of personal protective equipment.”Câu 38: Which best serves as the title for the passage?
