COVID-19 updates: 345 children currently hospitalized with coronavirus in Texas

The World Health Organization opened a center in Berlin on Wednesday that will gather, assess and share information internationally to help prepare for the next global health crisis.

The so-called "WHO Hub for Pandemic and Epidemic Intelligence" is receiving an initial investment of $100 million from Germany and will be led by Dr. Chikwe Ihekweazu, director-general of Nigeria's Center for Disease Control. The facility "will harness broad and diverse partnerships across many professional disciplines, and the latest technology, to link the data, tools and communities of practice so that actionable data and intelligence are shared for the common good," according to a press release from the WHO.

"The world needs to be able to detect new events with pandemic potential and to monitor disease control measures on a real-time basis to create effective pandemic and epidemic risk management," Dr. Tedros Adhanom Ghebreyesus, director-general of the WHO, said in a statement Wednesday. "This Hub will be key to that effort, leveraging innovations in data science for public health surveillance and response, and creating systems whereby we can share and expand expertise in this area globally."

"All the work that goes into pandemic and epidemic preparedness must occur before an outbreak starts," Tedros added. "Data linkage and analysis, and the ability to better detect and assess risks of disease events in their earliest stages before they amplify and cause death and societal disruption, is what the WHO Hub will focus on."

The ongoing coronavirus pandemic was the impetus for the hub's creation.

"Despite decades of investment, COVID-19 has revealed the great gaps that exist in the world’s ability to forecast, detect, assess and respond to outbreaks that threaten people worldwide," Dr. Michael Ryan, executive director of the WHO’s Health Emergency Program, said in a statement Wednesday. “The WHO Hub for Pandemic and Epidemic Intelligence is designed to develop the data access, analytic tools and communities of practice to fill these very gaps, promote collaboration and sharing, and protect the world from such crises in the future.”

On average, approximately 12,200 Americans are being admitted to the hospital each day with COVID-19. The forecast models used by the CDC suggest that by Sept. 27, that number could surge to as high as 22,400 a day. 

The lower end of the forecast puts the daily hospital admissions at around 6,400.

There are signs the rate of hospital admission nationwide may be slowing, with the U.S. Centers for Disease Control and Prevention reporting hospital admissions will likely "remain stable or have an uncertain trend over the next 4 weeks." 

Kentucky currently tops the list of states expected to see the most hospital admissions, per capita, in the next two weeks, followed by Florida and Georgia.

The American Medical Association, American Pharmacists Association and American Society of Health-System Pharmacists are calling for an "immediate end" to prescribing, dispensing or using the deworminig drug ivermectin to treat or prevent COVID-19. 

Ivermectin is available in different formulations for both people and animals to treat parasites. It is not approved to treat or prevent COVID-19, nor is there enough evidence to support its use. Though amid a surge in COVID-19 cases in the U.S., internal data from the Centers for Disease Control and Prevention reviewed by ABC News estimates a 19-fold increase of the medicine being distributed during the first week of August, alongside an increase in reported cases of illness related to ivermectin toxicity.

The prescribing and dispensing of ivermectin has increased 24-fold since before the pandemic, according to the medical and pharmaceutical associations, which said in a joint statement they were "alarmed" by an exponential increase in recent months as well.

"[We] are urging physicians, pharmacists, and other prescribers -- trusted healthcare professionals in their communities -- to warn patients against the use of ivermectin outside of FDA-approved indications and guidance, whether intended for use in humans or animals, as well as purchasing ivermectin from online stores," the associations said. "Veterinary forms of this medication are highly concentrated for large animals and pose a significant toxicity risk for humans."

Moderna has submitted initial data to the U.S. Food and Drug Administration on its vaccine booster, the pharmaceutical company announced Wednesday.

Its booster candidate would be half the dose (50 micrograms) of the original dosing (two shots of 100 micrograms each).

Federal officials have said they hope to begin administering booster shots for many Americans starting on Sept. 20, with the third shot at least eight months after the second.

The FDA has only authorized booster shots of Pfizer's and Moderna's COVID-19 vaccines for people who are immunocompromised. The Centers for Disease Control and Prevention's independent advisory board also recommended booster shots for those with weakened immune systems.

Pfizer is also seeking authorization for a third dose of its COVID-19 vaccine. The FDA announced Wednesday it will hold a public meeting of its independent advisory committee on Sept. 17 to discuss the application.
