Novel coronavirus pneumonia is worse than data shows, Robert Redfield, director of the CDC, director of the BGR, told reporters.The true number of covid-19 infections may be 10 times higher than the number of diagnoses confirmed by tests.The estimation is based on antibody detection.

Even without a surge in Texas, Florida, California and other states, U.S. officials did not have a complete picture of the covid-19 epidemic in the United States. Due to the lack of testing, it is not possible to test all suspected patients in the first few months of the outbreak. The problem of antibody detection will further hinder the accurate collection of data.

Knowing exactly how many people are infected is a key detail in planning future measures, whether it's blockages, open economies, or vaccination campaigns. Accurate case numbers will also benefit researchers, as they will provide more accurate data on asymptomatic numbers and true mortality. As of Friday local time, more than 2.46 million new crown cases have been confirmed in the United States. So far, nearly 125000 patients have died in the United States.


"The virus has caused so many asymptomatic infections ," Redfield said through The Hill Thursday.

CDC data appears to be consistent with other regions. In mid May, Spanish researchers published a study showing that the real number of cases of covid-19 in the country could be around 5% of the population, or 2.35 million. At the time, Spain had more than 272000 confirmed cases, one tenth of which were fatal. Spain was once the epicenter of the covid-19 epidemic in Europe, but successfully flattened the curve significantly.

Unlike the Spanish study, Redfield did not provide complete data. "This outbreak is not over. The pandemic is not over. The most powerful tool we have, the most powerful weapon, is to keep social distance, "Redfield said. "We have a responsibility to practice social mitigation strategies, protect vulnerable groups, and protect the elderly."

The CDC is monitoring conditions in about 20 states, where 100 CDC staff are helping authorities deal with the surge. "We are not talking about the second wave, we are still in the first. And this first wave is coming in a different form, "Redfield said.
