MIF, managed isolation facility MQF, managed quarantine facility. Positive SARS-CoV-2 rRT-PCR test results are indicated by (+) negative rRT-PCR test results are indicated by (–). Episodes of simultaneous door-opening between room 277 and rooms 276/278, each lasting 3–5 seconds, are indicated with ↓1 to ↓4. Map-arrow symbols indicate country of origin (Philippines and United Arab Emirates) airplane symbols denote date of arrival in New Zealand. The doors to the rooms were 2.135 m apart. Person A occupied room 277 and travel group BCDEF occupied adjoining rooms 276 and 278 on the opposite side of the corridor in block 2 of the MIF. Syringe symbol indicates person was fully vaccinated against coronavirus disease. Colors indicate persons A–F bars represent each person’s infectious period of 10 days after symptom onset or the first positive rRT-PCR test. Timeline of infectious periods, test results, and relative locations of persons A–F, implicated in airborne transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant between separate nonadjacent rooms within a tightly monitored MIF, New Zealand. Along with the United States, other countries have seen a rapid increase. The particles can also linger in the air after a person has left the room they can remain airborne for hours in some cases. Particles from an infected person can move throughout an entire room or indoor space. However, researchers say that more on-board precautions and screening procedures are warranted.Figure 1. CDC Guidelines for COVID After five waves of COVID-19 in the last two and a half years, cases of coronavirus have reappeared in the United States, and health experts have already declared it the 6th wave of COVID-19 in the country. Transmission of COVID-19 from inhalation of virus in the air can occur at distances greater than six feet. The study was conducted before mask mandates were required on flights, which was noted to help reduce the risk of transmission. As one of the first studies to analyze the dangers of in-flight transmission of COVID-19, researchers note that the most likely route of spread during the flight is via aerosol or droplet transmission, especially among passengers in business class, as well as during pre-departure and boarding. Reported by The Hill, a novel study by the CDC found that 1 person with COVID-19 infected 15 others during a long-haul flight from London to Vietnam in early March. In an appearance on “ Face the Nation,” Gottlieb cited the announcement as the “wrong move at the wrong time.” Flying During the Pandemic During his tenure as the former FDA commissioner, Scott Gottlieb was a known opponent to the proposed policy. While it is unclear how the memo may change the vetting and approval process for a COVID-19 vaccine, the new policy could lead to delays in the regulatory process. Reported by The New York Times, HHS Secretary Alex Azar issued a memo on September 15 stating the FDA no longer has the authority to sign any new rules regarding the nation’s foods, medicines, medical devices, and vaccines, a power that Azar notes is reserved to himself. The Hill reported that the CDC said the guidance posted Friday was a “draft version of proposed changes.” HHS Secretary Issues Rule-Making Authority Over FDA The Hill and The Washington Post reported that the CDC says the document was posted in error. The CDC removed from its website Monday revised guidance, published Friday, saying that the transmission of coronavirus disease 2019 (COVID-19) is airborne.
