Coronavirus latest: 5 states removed from New York travel advisory list

Germany has issued a travel warning for parts of France, including Paris and Marseille, due to high levels of coronavirus infection there.

The German government announced Monday that travelers returning from Ile-de-France and Provence-Alpes-Cote-d’Azur regions will be required to be tested for COVID-19 upon arrival and then must self-quarantine while awaiting the test results.

France’s national public health agency recorded 1,955 new cases of COVID-19 and 15 coronavirus-related fatalities on Monday, bringing the total to 244,854 confirmed cases and 30,528 deaths. The country is among the hardest-hit in Europe.

People younger than 60 are potentially driving the spread of the coronavirus pandemic in Georgia, according to a new study.

The study by the National Academy of Science collected data from five counties in Georgia, including four metro Atlanta areas, between March and May. An analysis of the data showed that people under the age of 60 were almost three times as likely to spread COVID-19 as people older than 60.

Researchers also found that people younger than 60 tended to be responsible for super-spreading events. Overall, 2% of cases were directly responsible for 20% of all infections, according to the study, which was published last Thursday in Proceedings of the National Academy of Sciences, the official journal of the National Academy of Sciences.

Palestinian authorities have imposed a 48-hour lockdown on the besieged Gaza Strip after officials said a family of four tested positive for COVID-19 at a refugee camp there.

The Palestinian health ministry said another case was identified Monday at a quarantine center in Gaza, bringing the total count to five.

The cause of the cluster is unclear and authorities are working to trace it. It’s the first known instance of the novel coronavirus spreading through Gaza’s local community.

The full lockdown went into effect Monday night across the entire 140-square-mile-long coastal enclave, which shares borders with Egypt and Israel.

The Gaza Strip, a densely populated area that forms part of the so-called Occupied Palestinian Territories, is inhabited by some 2 million Palestinians, most of whom are registered refugees living in overcrowded camps. Both Egypt and Israel have imposed restrictions on movement in and out of Gaza, citing concerns over the militant group Hamas, which rules the territory and has been designated a terrorist organization by Israel and the United States.

However, a small number of Palestinians still travel to Jerusalem for routine cancer treatments, and Egypt partially lifted its blockade recently to allow Palestinians back in.

The University of Southern California is reporting an “alarming increase in the number of COVID-19 cases” among students living in off-campus housing.

In a letter sent to students Monday, the university’s student health center said it had identified 43 cases in the past seven days. All cases are related to students in off-campus living environments, and more than 100 students are now in a 14-day quarantine due to exposures.

“This increase comes despite the continued state and county health guidance that significantly restricts in-person instruction and on-campus activities for universities located in counties that are on the state’s COVID-19 monitoring list, including Los Angeles County,” the letter states. “We continue to strongly discourage students from returning to the campus area until further notice.”

The private university, located in the heart of Los Angeles, kicked off its fall semester online last week, but many students remain in apartments and off-campus residences near the campus.
