The situation with COVID-19 is ever evolving.

From changing mask rules to COVID-19 subvariants and the end of the “full-blown pandemic phase” things are changing constantly. Now, a new COVID-19 variant — BA.2.12.1 has hit the scene. It’s one you may have already started to hear about in the news and one you may hear a bit more about in the coming weeks. So just what is this variant, what signs should you look for, and what impact could it have on your trip? Here’s what we know so far.

What is BA.2.12.1?

Over the past years, the virus that causes COVID-19 has mutated and changed. For a while, we shared a lot about the Delta variant and then the Omicron variant. Following that, BA.2 or “stealth Omicron,” as it was originally called, became a hot topic. BA.2 is a subvariant of Omicron.

BA.2.12.1 is a NEW and “highly transmissible” subvariant of COVID-19, according to US News & World Report. On May 3rd, 2022, US News & World Report shared that this particular subvariant was actually responsible for more than 1/3 of COVID-19 cases during the previous week.

In weeks before that it had only made up 27% or 17% of cases. According to Deadline, the jump in cases attributed to BA.2.12.1 is close to 100% within just a period of two weeks.


CDC Director Rochelle Walensky has indicated that BA.2.12.1 could be 25% more transmissible than BA.2. It is still unclear how BA.2.12.1 could affect COVID-19 vaccines. (US News & World Report)

Director Walensky has said, “Additional evaluation is currently underway to understand the impact of BA.2.12.1 on vaccine effectiveness…But importantly, we continue to believe that those who are vaccinated and especially those who are boosted, continue to have strong protection against severe disease, even from BA.2.12.1.” (US News & World Report)

Cases and hospitalizations have started to increase in the US when it comes to COVID-19, according to Deadline.

Charts from Google, using data from The New York Times, show that the 7-day average of COVID-19 cases was 71,105 on May 6th.


Compared to the 7-day average of 33,103 on April 11th, 2022, this is a large increase, though still less than some other numbers seen earlier in the year.

Severity & Symptoms

In terms of severity, the World Health Organization previously shared that the evidence currently doesn’t suggest that there are differences in terms of “severity or clinical manifestations” when it comes to BA.2.12.1 versus BA.2. (US News & World Report)

NBC Chicago echoes this by noting that “While the new subvariant is reported to be more transmissible, there’s no evidence to suggest that it causes more severe disease.”

According to the Palm Beach Post, Florida International University epidemiologist Dr. Mary Jo Trepka has said, ““In terms of severity, it doesn’t seem like we’re experiencing what we did with delta or omicron…But I think it’s too early to make any predictions…Even with omicron, it took several weeks to see its effects on hospitals.”

Overall, symptoms of COVID-19 in general include fever or chills, cough, muscle or body aches, sore throat, new loss of taste or smell, and others. NBC Chicago shares that”It remains unclear if certain symptoms are associated with BA.2.12.1 infections.”

what next?

As Deadline puts it “the freight train hasn’t stopped with BA.2.12.1.” In early May, they shared that the first 2 cases of newer variants were discovered in the US. These newer variants are expected to be more infectious than BA.2.

But, according to NBC Chicago, “Experts generally agree that the public shouldn’t worry too much about the emergence of each omicron subvariant.”


David Montefiori, who is a professor at the Human Vaccine Institute at Duke University Medical Center, said: “At some point, you just can’t get nervous every time there’s a new variant, because there’s always going to be a new variant…We’ve been through multiple waves of variants that really mattered a lot, but we might be coming out of that because there’s so much immunity built up in the population.” (NBC Chicago)

How is Florida Being Impacted?

In Florida, COVID-19 cases have gone up. According to the Palm Beach Post, the wave of COVID-19 infections is “worsening” in parts of Floridabut is still generally “milder” than the surge that took place with Omicron.

In early May of 2022, the Palm Beach Post shared that health officials in Florida “logged the biggest increase in new cases since late February, but hospitalizations remain lower than before the omicron variant engulfed Florida.”

COVID-19 Warning Sign

In Florida, there have been around 29,715 new infections each week since April 22nd, 2022. In terms of hospitalizations, Florida hospitals “tended to an average of 981 COVID-positive patients per day” during a week in early May. That number has increased since April 14th, but is still lower than the high numbers seen in December of 2021.


As of May 7th, 2022, the 7-day average for deaths due to COVID-19 was 20. You can see how these numbers have increased and decreased over the last 30 days in the chart below.


According to the Palm Beach Post, Dr. Kitonga Kiminyo, who is “an infectious disease specialist in Boynton Beach,” said “We are not seeing any increase in COVID admissions or hospitalizations at this particular time…[but] With the continued unmasking in the community and the rising cases in the community, we expect to start seeing cases in the hospitals perhaps in the next few weeks.”

What About Disney World?

Over at Disney World, rules and regulations have not yet changed since the last update. Masks are no longer required in outdoor or indoor locations, and are not required on Disney transportation either.

But Disney does recommend that guests who are not fully vaccinated continue to wear a mask in indoor locations and enclosed transportation.


We’ve also seen a number of reopenings announced, entertainment offerings set to return soon, and big crowds. Based on what we’ve seen, changes in mask rules, distancing requirements, or things of that nature seem a bit more likely than reclosures, though we’ve seen some Disney parks overseas close due to COVID-19.

Things, of course, could change at Disney World in the future as the situation with COVID-19 continues to develop.
