CDC data shows that after seven days, the risk of transmission is drastically reduced. "In that five-to-seven-day window, you know, there's some depending on whether people have been vaccinated, underlying conditions, etc., but the risk drops a lot and the feeling is that in the general population, combined with masking, etc. the risk really is very low," Arwady explained.

But we’ve changed some of our recommendations about masking and other precautions for vaccinated individuals in certain ...
How long after I get COVID-19 will I test negative?
Some people can test positive for COVID-19 for weeks or even months on PCR tests, but there is good news: people are not likely to be contagious for that long from a single infection, even if they test positive, and therefore are unlikely to transmit the virus to others.
How Long is a Person Contagious after Coronavirus Exposure?
If you have been exposed to the coronavirus that causes COVID-19, you are at risk. When will you be able to tell whether you caught the deadly virus? The answer lies in the incubation period.
Incubation Period for the Delta Variant
The Delta strain has a shorter incubation period than previous SARS-CoV-2 variants which includes the alpha, beta, and gamma variants. Delta’s incubation period is approximately four days, which means if the Delta variant infects, you will start showing symptoms within four days.
Incubation Period for the Omicron Variant
The WHO has labeled the Omicron strain as a variant of concern; its incubation time may be shorter than earlier variants, with symptoms showing up within three days after contact in newly infected patients.

What Is the Incubation Period for the Delta Variant?
The Delta variant, which evolved from previous strains of COVID-19, is currently the most dominant type of coronavirus in the U.S. The mutation allows the virus to produce a higher load of viral particles in the body. This makes the Delta variant more than 2 times as contagious as other variants. In fact, one study from China showed that in infections caused by the variant, the viral load was 1,000 times more than that of previous coronavirus strains.

If 14 days of isolation creates a hardship, the CDC advises you may be able to leave quarantine: After day 10 without testing. After day 7 after receiving a negative test result.

The incubation of the delta variant takes up to four days, which is shorter compared to the original variant. According to a report by USA Today, this translates to increased rate of infection across many places, especially in regions that have high populations of unvaccinated individuals. The original variant can spread up to three people per day, but the delta variant has a higher infection rate of up to six people per day.
How much does the delta variant increase transmission rates?
But recent studies of the delta variant show a stunning 40-60% increase in transmission rates than the original SARS-CoV-2 alpha strain back in Wuhan.
Is the delta variant the fastest and fittest?
The delta variant's dangerous features convinced the World Health Organization (WHO) to consider it as the 'fastest and fittest' coronavirus variant throughout the pandemic.
Can you infect someone with Delta?
You can infect people sooner. If you develop symptoms and/or test positive, be aware that you could have infected others within a day and a half of becoming infected yourself. Make sure your contacts are identified and notified of their possible exposure. And bear in mind that because the Delta variant is more transmis sible, even brief encounters may have exposed someone else to the virus.
Is Delta the dominant form of the virus?

What is the Delta variant?
1. Delta is more contagious than the other virus strains. Delta is the name for the B.1.617.2. variant, a SARS-CoV-2 mutation that originally surfaced in India. The first Delta case was identified in December 2020, and the strain spread rapidly, soon becoming the dominant strain ...
When did the Delta variant surface?
Then, the Delta variant surfaced in the United States. First identified in India in December 2020, Delta swept rapidly through that country and Great Britain before reaching the U.S., where it quickly surged.
