Today marks 100 days since the World Health Organisation was informed of Chinese patients suffering from pneumonia, caused by a mystery virus.
The cases were in Wuhan, the capital of Hubei province, and health officials in China had already begun to suspect the outbreak could be a coronavirus similar to Sars, the respiratory disease that killed 774 of the 8,096 people who caught it between 2002 and 2004.
After being told about the new coronavirus on December 31, the WHO published information about the outbreak on its website on January 5.
It said there was “limited information to determine the overall risk” and the “WHO does not recommend any specific measures for travellers”.
It has changed the lives of billions of people, from those mourning the more than 76,000 who died after contracting the virus and the medics treating hundreds of thousands of cases, to the millions who lost their jobs as the pandemic necessitated quarantine measures across the globe.
Those early dispatches seem to come from another life and there is now unlikely to be anyone in the world who is not aware of Covid-19, the disease caused by the virus.
There is no vaccine yet and no medicine is certain to ease a patient’s symptoms, which include a fever and cough.
Ventilators to keep the most critically ill alive are in short supply, as is protective equipment for healthcare workers on the front lines in the fight against the virus.
Some countries have weathered the storm better than others.
Nations such as South Korea and Singapore, using experience gained during the Sars outbreak, had more advanced testing regimes in place.
But the suffering and disruption in the countries has been minimised, rather than avoided altogether.
Some of the decision taken by countries now appear unwise, with hundreds of thousands of young people allowed to mingle during spring break in the US, even as the virus spread across North America.
In the UK, a four-day horse racing festival in Cheltenham went ahead only two days before the WHO declared the outbreak was a pandemic.
An early plan to allow the virus to spread to build up 'herd immunity' in 40 million Brits was hastily abandoned when researchers predicted an appalling death toll in the hundreds of thousands.
The UAE has been widely regarded as having reacted quickly to the threat posed by Covid-19. By late January, it had introduced thermal scanning at airports, beginning with passengers arriving from China.
The first cases in the UAE were reported by the end of the month – four members of a family from Wuhan who travelled to the Emirates for a holiday.
As the number of cases increased, slowly at first, the country began to ramp up its response, with measures including a nationwide sanitisation programme and calls for people to remain in their homes to stem the spread of the virus.
Authorities will hope the steps taken will give the country an even better degree of control over the outbreak and bring a full recovery closer.
