Some Youth Sports To Resume Next Month

Low-contact high school sports will begin practice and games starting next month, Governor Andrew Cuomo announced on Monday, while other youth recreational activities remain in limbo.

Tennis, soccer, cross country, field hockey and swimming can resume in schools across the state on September 21st. Meanwhile, higher-risk sports, such as ice hockey, wrestling, and football, will be barred from competing until at least October 19th. They will still be permitted to practice during that time, according to the governor.

“We’re doing this in phases. We want to see what the effect is. We want to see how it works,” Cuomo said. For now, teams will only be permitted to play within their own counties. (His office did not immediately respond to a request for clarification on when basketball can begin).

Like so many aspects of New York's reopening plan, the guidance and restrictions on youth sports remains convoluted.

Last week, the city's Parks Department announced that they won't be issuing field permits to youth sports organizations this year, prompting scores of disappointed letters from parents and a petition with more than 5,000 signatures.

"Without permits to these fields, these organizations will be unable to offer programming leaving a devastating hole in the lives of tens of thousands of children and young people," it reads.

But the city's parks department later clarified that the fields will still be available on a first-come, first-served basis.

At least one Manhattan Little League has seen the effects of this hands-off approach already this summer: complaints from parents about coaches not wearing masks; angry calls to a congress person; and threats of lawsuits.

Could The State Block A Bad Vaccine? Cuomo Says He'll Investigate

Governor Andrew Cuomo said he would investigate whether the state health department has the authority to overrule federal approval of a COVID-19 vaccine, amid rising concern that President Trump could attempt to push through an unsafe treatment before the November election.

"Can the DOH overrule an FDA approval? That is a legal question that we are looking at," Cuomo said during a press conference on Monday. "Part of it depends on the apparent efficacy of the vaccine. If it's a political vaccine, and there's no bonafides, that's one situation. So it will depend on the facts."

The Financial Times reported on Sunday that Trump is mulling a plan to fast-track a coronavirus vaccine, currently under development in the U.K., ahead of the presidential election.

His top officials have also reportedly discussed granting emergency approval to a vaccine through the Food and Drug Administration as early as September — stoking fears that the administration is cutting corners on safety that could undermine public trust of an issue of grave importance.

On Sunday night, Trump announced that the agency was granting an emergency use authorization of convalescent plasma to treat hospitalized coronavirus patients. The previous day, the president accused the "deep state, or whoever" at the FDA of delaying treatment options for political reasons.

Health officials and top scientists have expressed skepticism about the newly-authorized treatment, describing plasma as an experimental therapy that requires further testing. It's unclear whether the treatment will be immediately available in New York.

"I don't know what the president is talking about," Cuomo said on Monday, when asked about the authorization. "We're going to look at what he said. We're having the Health Department review it."

Danbury, CT Residents Urged To Stay Home After COVID-19 Outbreak Spreads

A recent surge in COVID-19 cases in Danbury, Connecticut has prompted officials to warn people to stay at home as much as possible.

The Connecticut Department of Public Health declared a COVID-19 alert for the city on Friday in response to the increase in cases. Between August 2nd and August 20th, the city recorded at least 178 new cases of the virus, compared to 40 over the previous two weeks.

“This is a serious outbreak in Danbury and we really need an all hands on deck approach,” Deidre S. Gifford, the state's acting Department of Public Health commissioner, said in a statement.

Officials say that much of the outbreak involves Danbury residents who have recently traveled out of state. As with New York, the state requires anyone coming from "restricted states" to self-quarantine for 14 days, and they urge anyone traveling internationally to also self-quarantine after returning. In addition, they are also asking people people to cooperate with contact tracers and get tested immediately if they think they may have been exposed.

Barbecues and youth sports have also been linked to the outbreak; the city canceled its youth sports leagues last week as a result.

In the meantime, officials are telling Danbury residents to stay home, limit indoor gatherings, and avoid attending church services and other big events.

Last month, a series of teen parties celebrating high school graduations were blamed for a "mini surge" of COVID-19 cases in Greenwich, Connecticut.

Hong Kong Researchers Report First Case Of COVID-19 Reinfection

An upcoming study by researchers at the University of Hong Kong has reported the first case of an individual who was reinfected with coronavirus, suggesting that immunity against the virus lasts only a few months.

"This case illustrates that re-infection can occur just after a few months of recovery from the first infection. Our findings suggest that SARS-CoV-2 may persist in the global human population as is the case for other common-cold associated human coronaviruses, even if patients have acquired immunity via natural infection," researchers said in a press release on Monday.

Previous reports of second infections in the U.S. and elsewhere have not been backed up by more testing. Previously infected individuals have been known to shed the virus for weeks.

In the study, which has been accepted for publication by the journal Clinical Infectious Diseases, researchers said they discovered a 33-year-old information technology worker who tested positive for coronavirus 4.5 months after his first infection. The second infection was detected during an airport screening as the man traveled from Europe to Hong Kong. Using genomic sequence analysis, scientists at the University of Hong Kong were able to determine that he had been infected by two different strains.

In another notable finding, the man did not develop any symptoms from his second infection, suggesting that “subsequent infections may be milder,” the researchers said.

The latest study could have a significant impact on vaccine development and how governments continue to combat the pandemic. While the hope had been that the new coronavirus would resemble SARS and MERS, two other coronaviruses, and confer immunity lasting more than year, research is increasingly finding that it might instead behave more like the common cold and continue to circulate in communities.

"Since the immunity can be short lasting after natural infection, vaccination should also be considered for those with one episode of infection," the researchers said, adding, "Patients with previous COVID-19 infection should also comply with epidemiological control measures such as universal masking and social distancing."

Recently, the Centers of Disease Control and Prevention issued new guidance that said people who have tested positive for COVID-19 do not need to quarantine or get tested again for up to three months as long they do not develop symptoms.

The recommendation was largely interpreted as the CDC recognizing that people with covid have short-term immunity, although the agency later issued a statement rejecting that assumption.

In June, a study published in Nature found that a high proportion of patients began to show decreasing levels of immunity 2–3 months after infection. In addition, the researchers said that, especially in cases where individuals are asymptomatic or have less severe symptoms, the antibodies may not last very long.
