Americans who test positive for COVID-19 but do not have symptoms can stop isolating after five days as long as they continue wearing masks, the Centers for Disease Control and Prevention announced on Monday, halving the agency's previous isolation period down from 10 days.
The CDC also said it was loosening its guidance for quarantining after a COVID-19 exposure for unvaccinated Americans or those eligible for a booster who have not yet received their additional shot. It now recommends a five-day quarantine followed by five days of strict mask-wearing, but says that if quarantine "is not feasible," it can be skipped as long as they wear a mask in the 10 days after exposure.
The CDC says people who are fully vaccinated and boosted do not need to quarantine after exposure. The agency had previously said all vaccinated Americans, regardless of whether they had received a booster shot, did not need to quarantine after a close contact as long as they did not have symptoms.

NASA announced ambitious long-range plans Tuesday to spend $20 billion over the next seven years to build a moon base near the lunar south pole featuring habitats, pressurized rovers and nuclear power systems. The announcement came just over a week before the planned launch of NASA's Artemis II around-the-moon mission. In:
