Covid’s first dynamic surveillance system spread to 195 nations

New York, December 6 (IANS): First, a team of scientists has developed a new global Covid-19 surveillance system that can dynamically track not only where the virus is now, but also where it is going, how fast it will arrive and whether that speed is accelerating.

The new surveillance system has now been introduced in 195 countries.

“We can now easily identify epidemics at their onset,” said Lori Post of Feinberg University School of Medicine at Northwestern University.

“You want to know where the pandemic is accelerating, how fast it is moving and how it compares to previous weeks.

James Omke of Northwestern University and Charles Moss of the University of Florida have been working for the past four months to develop a new oversight system.

“We can inform leaders where the epidemic occurs before it occurs in overcrowded hospitals and morgues,” Post said. “Current systems are static and ours are dynamic.

Dash will monitor each country ‘s dashboard to inform policy leaders around the world. Users will have metrics around the world at their fingertips.

The new system and the first U.S. surveillance report were published in the Journal of Internet Medical Research.

The global surveillance application analyzes the virus in the same way the field of economics measures the expansion and contraction of the economy.

“These methods have been tried and tested, but this is the first time they have been applied to disease surveillance,” Post said. “We had a validated model and metrics for medical supervision and published. “We know they work.”

Existing surveillance, which has not changed much in the last 50 years, measures the burden of new and cumulative deaths and infections.

They do not identify significant pandemic shifts or alarms when there is concern about accelerating disease transmission that signals an outbreak.

These new standards can help developed countries and their health systems prepare for rapid changes in the pandemic.

The system also checks for incomplete data using state-of-the-art statistical methods.

Existing oversight takes serious cases, the Post said, so in Covid’s case, those figures probably represent only 10 to 20 percent of the freight.
