The US President has tested negative for COVID-19 after taking a second PCR test on Wednesday. Earlier, it was reported that Biden was exposed to an aide, who later tested positive while travelling on Air Force One on Friday.
Following the incident, the President tested negative with an antigen test on Sunday and got a negative result with a PCR test on Monday.
The results come after a fully vaccinated staff member who flew with the President on Air Force One on Friday started experiencing symptoms of the virus on Sunday.
Speaking to reporters on Wednesday, Press Secretary Jen Psaki noted that CDC guidelines do not require those who are fully vaccinated to quarantine after exposure and that the President will resume with his daily schedule.
Biden, who is 79 years old, is the oldest president in United States history. He has been vaccinated against the coronavirus, receiving a booster shot in September. The president has also called on Americans to get booster jabs as soon as possible amid fears of the quick-spreading Omicron variant.
On Monday, the US Centers for Disease Control and Prevention (CDC) announced that Omicron has become the dominant coronavirus strain in the country, making up 73% of the new COVID-19 cases registered during the previous week.
