Robert Redfield, director of the U.S. Centers for Disease Control and Prevention (CDC), told reporters that the actual number of new pneumonia in the U.S. is worse than the data show,media BGR reported. The true number of COVID-19 infections may be up to 10 times higher than the number of diagnoses confirmed by testing. This estimate is based on antibody testing.
Even without a surge in Texas, Florida, California and other states, U.S. officials have no complete picture of the COVID-19 outbreak in the United States. In the first months of the outbreak, all suspected patients could not be tested due to a lack of testing. Problems with antibody detection further hinder accurate data collection.
Knowing exactly how many people are infected is a key detail in planning future measures, whether it’s blocking, opening up the economy, or vaccination campaigns. Accurate case figures will also benefit researchers because they will provide more accurate data on asymptomatic numbers and true mortality. As of Friday local time, the number of new confirmed cases in the United States had exceeded 2.46 million. So far, nearly 125,000 patients have died in the United States.
“This virus causes so many asymptomatic infections,” Redfield said Thursday through The Hill. “We’ve probably found about 10 percent of the outbreaks. He explained that serological surveys are collected for coronavirus testing and other causes, such as blood donation and laboratory testing. They show that 5 to 8 percent of Americans are infected with the virus.
The CDC’s figures appear to be consistent with those in other regions. In mid-May, Spanish researchers published a study showing that the true number of COVID-19 cases in the country could be around 5 percent of the population, or 2.35 million. At the time, there were more than 272,000 confirmed cases in Spain, one in ten of which were fatal. Spain was once the centre of the COVID-19 outbreak in Europe, but managed to level the curve significantly.
Unlike the Spanish study, Redfield does not provide complete data. “This outbreak is not over yet. The pandemic is not over yet. The most powerful tool we have, the powerful weapon, is to keep the social distance,” Redfield said. “We have a responsibility to implement social mitigation strategies to protect vulnerable groups and the elderly. “
The CDC is monitoring about 20 states where 100 CDC staffers are helping authorities deal with the surge in cases. “We’re not talking about the second wave right now, we’re still in the first wave. And that’s the first wave coming in a different way,” Redfield said.
