On June 16, 2021, the CDC lowered their cruise Tavel advisory from Level 4 to Level 3, and specified the notice is for travelers who are not fully vaccinated.
According to the latest from the advisory pertaining to COVID-19 and Cruise Ship Travel passengers the aCdc recommends the following to passengers who are not full vaccinated:
- CDC recommends that people who are not fully vaccinated avoid travel on cruise ships, including river cruises, worldwide. Since the virus spreads more easily between people in close quarters aboard ships, the chance of getting COVID-19 on cruise ships is high. It is especially important that people who are not fully vaccinated with an increased risk of severe illness avoid travel on cruise ships, including river cruises.
- Cruise passengers who are not fully vaccinated are more likely to get COVID-19, which spreads person-to-person, and outbreaks of COVID-19 have been reported on cruise ships.
- People who decide to go on a cruise should get tested 1–3 days before their trip and 3–5 days after their trip.
- In addition to testing, passengers who are not fully vaccinated should self-quarantine for 7 days after cruise travel, even if they test negative. If they do not get tested, they should self-quarantine for 10 days after cruise travel.
