Virus review: Dangerous blood clots pose perplexing threat; Georgia governor offers to host RNC

{{featured_button_text}}

Blood clots that can cause strokes, heart attacks and dangerous blockages in the legs and lungs are increasingly being found in COVID-19 patients, including some children. Even tiny clots that can damage tissue throughout the body have been seen in hospitalized patients and in autopsies, confounding doctors’ understanding of what was once considered mainly a respiratory infection.

Doctors and scientists at dozens of hospitals and universities around the globe are seeking answers while trying to measure virus patients’ risks for clots and testing drugs to treat or prevent them.

Some conditions that make some COVID-19 patients vulnerable to severe complications, including obesity and diabetes, can increase clot risks. But many authorities believe how the virus attacks and the way the body responds both play a role.

Meanwhile, a U.S. travel ban takes effect Tuesday for foreigners coming from Brazil. On top of that, the South American country got a warning from the U.N. health agency not to reopen its economy before it can perform enough tests to control the spread of the coronavirus. India reported a record single-day jump in new infections for the seventh straight day and Russia had a record number of daily coronavirus deaths.

In other developments:

  • Georgia’s governor is offering his state as the host of the Republican National Convention — a day after President Donald Trump threatened to pull the convention out of North Carolina if that state’s Democratic governor didn’t assure Trump that the August gathering can go forward despite coronavirus fears. Georgia Gov. Brian Kemp, a Republican, sent an open plea to Trump on Tuesday to consider his state as an alternate site for the convention, which is set to gather more than 2,500 delegates and thousands more guests, press and security officials.
  • The New York Stock Exchange reopened for in-person trading for the first time in two months. The trading floor in lower Manhattan opened with plastic barriers, masks and a reduced number of traders to adhere to the 6-foot social-distancing rule.
  • Congress is wrestling over whether to “go big,” as House Speaker Nancy Pelosi wants for the next relief bill, or hit “pause,” as Senate Majority Leader Mitch McConnell insists. It’s a defining moment for the political parties heading toward the election and one that will affect the livelihoods of countless Americans suddenly dependent on the federal government. Billions of dollars in state aid, jobless benefits and health resources are at stake.
  • The NHL will abandon the rest of the regular season and go straight into the playoffs with 24 teams instead of 16 if it is able to resume play. The decision, announced Tuesday by Commissioner Gary Bettman, is not a guarantee that games are coming back.
  • Sweden’s government defended its response to the COVID-19 global pandemic on Tuesday despite the Scandinavian country now reporting one of the highest mortality rates in the world with 4,125 fatalities, or about 40 deaths per 100,000 people.
  • Manaus is one of the hardest hit cities in Brazil, but in the absence of evidence proving otherwise, relatives are quick to deny the possibility that COVID-19 claimed their loved ones, meaning that the national death toll of more than 23,000 toll is likely a vast undercount.
