August 28|

The Pan American Health Organization (PAHO) has recently published a technical note on two variants of Omicron, descendants of the coronavirus, which have been under scrutiny in recent months.

These are the variants known scientifically as EG.5 and BA.2.86 and, to date, the findings suggest that, despite their presence, there appears to be no significant change in their impact on public health.

EG.5, the variant that put scientists on alert
EG.5, a variant derived from XBB.1.9.2 (itself from Omicron), was first detected in February 2023. But it was only last August 9 that health authorities classified it as a “Variant of Interest” (VOI). The PAHO report notes that there has been a steady increase in the proportion of reported EG.5 infections worldwide, and that countries such as Canada, Colombia, Costa Rica, the United States and the Dominican Republic have also noted this trend. However, so far, no significant changes in disease severity related to this sublineage have been detected.

BA.2.86, variant under surveillance
BA.2.86 initially emerged in a sample taken in Denmark at the end of July 2023. Although it has been detected in other regions, only a total of seven sequences have been reported to date. The World Health Organization (WHO) classified it as a variant under surveillance on August 17 because it has a considerable number of mutations in the genes of the virus spicule.

So far, the available evidence on BA.2.86 is limited, which has led PAHO to indicate that “initial risk assessment will be generated shortly”. This suggests that more research is needed to better understand its transmission capacity, its ability to evade immune response and its potential severity.

Public health risk alert
PAHO has assessed the public health risk posed by EG.5 as low and comparable to that of other currently circulating variants of concern. However, the outlook for BA.2.86 is still under evaluation, underscoring the importance of maintaining constant vigilance on these emerging variants.

PAHO together with the World Health Organization (WHO) have reiterated that the recommendations to combat the spread of COVID-19 remain unchanged. In addition, it has urged all countries in the region to continue to collect representative samples for sequencing and to maintain adequate genomic surveillance of SARS-CoV-2. This is essential as the virus continues to circulate and evolve.

WHO warns that many countries are underreporting new cases
Maria Van Kerkhove, WHO technical lead for COVID-19 issues, has reported that the EG.5 variant of the Omicron virus has a higher transmission capacity, but does not appear to be more severe than other variants.

In Van Kerkhove’s words, “we did not detect a change in the severity of the EG.5 variant compared to other Omicron sublineages that have been circulating since late 2021.” This suggests that, despite its increased ability to transmit, the EG.5 variant does not appear to cause a more severe form of the disease compared to other previously identified Omicron variants.

For his part, WHO director general Tedros Adhanom Ghebreyesus expressed concern that many countries were not reporting COVID-19-related data to WHO. He said that only 11% of countries had reported on hospitalizations and intensive care unit (ICU) admissions related to the virus.

In response to this situation, WHO issued a set of standing recommendations for COVID-19. In these recommendations, it urged countries to continue to report data on COVID-19, especially mortality and morbidity data, and to continue to offer vaccination.

Maria Van Kerkhove emphasized that the lack of data from many countries is hampering efforts to combat the virus. “About a year ago, we were in a much better situation to anticipate, act or be more agile. And now, the delay in our ability to do that is growing. And our ability to do so is decreasing,” he stressed.

The situation in the Americas
According to data provided by WHO, the health agency responsible for monitoring the evolution of the coronavirus worldwide, the last month has seen an alarming increase in the number of new cases of COVID-19, with more than 1.4 million new cases reported, representing a 63% increase compared to the previous period.

However, there has been a 56% decrease in the number of deaths during the same period. These data underscore the continued need to maintain stringent control and surveillance measures.

However, they stress that as the SARS-CoV-2 virus continues to evolve, it is essential to maintain constant monitoring of emerging variants such as EG.5 and BA.2.86.

Although the risks appear to be low at this time, the situation may change, and it is vital to follow the recommendations of public health authorities and maintain active surveillance to ensure an effective response to the ongoing pandemic.

White House says Cuba policy unchanged despite sanctioned fuel shipment

The White House said Monday that it has not changed its policy toward Cuba, despite allowing a sanctioned Russian oil tanker to deliver fuel to the island on humanitarian grounds.

U.S. officials emphasized that the decision was made as an exception and does not signal a broader shift in policy.

The administration added that similar decisions would be evaluated on a case-by-case basis, depending on humanitarian considerations.

The clarification comes amid ongoing restrictions related to U.S. sanctions policy, which continue to limit trade and financial flows involving Cuba.

Spain to grant citizenship to Venezuelan opposition leader Leopoldo López

The Spanish government is expected to grant citizenship this Tuesday to Venezuelan opposition leader Leopoldo Lópezthrough an extraordinary procedure known as “carta de naturaleza.”

The decision will be approved by royal decree, an exceptional legal mechanism used in special cases that require expedited resolution due to specific circumstances.

López has been living in Madrid since 2020, after leaving Venezuela following a prolonged political and legal conflict with the government of Nicolás Maduro.

According to government sources, López currently does not have a valid Venezuelan passport and faces difficulties in having his nationality fully recognized in his home country.

As a result, he applied for Spanish citizenship via a fast-track process at the end of 2025, after previously attempting to obtain it through regular procedures.

The Spanish government justified the move based on López’s international relevance and foreign policy considerations.

López is the leader of the Voluntad Popular party and co-founder of the World Liberty Congress, an initiative launched in 2022 alongside figures such as Garry Kasparov and Masih Alinejad.

ICE to remain at airports amid DHS shutdown, Homan says

The U.S. “border czar,” Tom Homan, said Sunday that agents from U.S. Immigration and Customs Enforcement (ICE) will remain deployed at airports until operations return to “100% normal,” as the shutdown of the Department of Homeland Security (DHS) continues.

“We will maintain ICE presence until airports feel they are fully back to normal operations,” Homan said during an interview on Face the Nation on CBS.

Homan justified the deployment on security grounds, noting that the measure was ordered by President Donald Trumpamid widespread absenteeism among agents of the Transportation Security Administration, who have gone without pay for over six weeks due to the DHS shutdown.

According to acting TSA administrator Ha Nguyen McNeill, at least 460 TSA agents have resigned during the shutdown, while daily absenteeism has averaged 11%, exceeding 50% at some airports.

Homan warned that if TSA staffing levels do not recover after the shutdown, ICE agents will continue filling the gap. “ICE is there to support our TSA brothers and sisters. We will remain as long as needed to ensure airport security,” he said.

The DHS shutdown reached 44 days on Sunday, making it the longest government shutdown in U.S. history. The impasse stems from disagreements between Democrats and Republicans over ICE funding.

A recent bipartisan Senate proposal to fund DHS without including ICE failed after being blocked by House Republicans, who insist on full funding for the agency.

Amid the deadlock, Trump signed an executive order directing Homeland Security Secretary Markwayne Mullin to immediately pay TSA agents to address what he called an “emergency situation” and restore order at airports, with payments expected to begin Monday.
