Epidemia en Europa: barbijos y preocupación en España por la variante K del virus H3N2 de la gripe A

Barbijos en el súper, en las escuelas, en los shoppings. La previa a las Fiestas se vive en España con preocupación y un dejà vu de los días de pandemia: porque la epidemia de gripe que acecha desde hace semanas ya supera los casos registrados en los últimos tres inviernos y amenaza con un pico de contagios después de Navidad.
Se trata de la variante K del virus H3N2 de la gripe A, que los españoles temen más que otros años aunque los especialistas aseguran que no se trata de una variante que afecte más gravemente al organismo.
Sin embargo, las guardias de los hospitales desbordan de consultas por síntomas agudos que no remiten y duran más de una semana. Fiebre aleatoria, tos seca, cuadros de sinusitis, mareos e imposibilidad de mantenerse en pie se repiten en las consultas.
Las cifras que maneja el Ministerio de Salud reflejan un adelanto de la epidemia de unas siete semanas, respecto de años anteriores.
En la Comunidad de Madrid, los casos aumentaron un 145 por ciento en la última semana y ya superaron el pico de contagios de los últimos tres inviernos.
Según un relevamiento epidemiológico de enfermedades respiratorias del Instituto de Salud Carlos III, la tasa de gripe en Atención Primaria pasó en la primera semana de diciembre 78,3 a 164,6 casos por cada 100.000 habitantes.
El grupo más afectado es el de los chicos de uno a cuatro años, entre quienes la incidencia pasó de los 214,7 hasta llegar a los 503,1 casos por cada 100.000 habitantes.
El estudio analiza, además, la incidencia en otros virus respiratorios como el VRS, que provoca la bronquiolitis en los nenes, y el SARS-CoV-2, el del Covid. Según el Instituto de Salud Carlos III, la tasa de Covid se sitúa en 4,1 casos por cada 100.000 habitantes. Una semana antes era de 3,7 casos.
Por eso, en Madrid, a partir del lunes 15 de diciembre será obligatorio el uso de barbijos en los hospitales y en los centros de salud de toda la comunidad autonómica. También están recomendados en las residencias de ancianos.
En Cataluña, donde los contagios registran picos aún mayores, esta semana ya se impuso el uso del barbijo en los hospitales y en los asilos.
La variante K no es más grave aunque sí presenta mutaciones significativas en la proteína que facilita la entrada viral en las células que infecta. Es por esto que la población no está inmunizada en particular ante esta variante de la gripe que afecta a España y a varios países de Europa, en particular, al Reino Unido, donde las internaciones aumentaron un 55 por ciento en una semana.
“Aunque existen algunas diferencias genéticas entre los virus de la gripe en circulación y las cepas incluidas en las vacunas, la vacuna contra la gripe estacional aún puede brindar protección contra virus derivados y otras cepas virales incluidas en la vacuna. Se espera que la vacunación proteja contra la enfermedad grave y sigue siendo una de las medidas de salud pública más eficaces”, señala la Organización Mundial de la Salud (OMS) en un comunicado que emitió este jueves.
En Madrid, el hospital de pandemias Enfermera Isabel Zendal, que se construyó en tres meses y se inauguró en tiempos del Covid, en diciembre de 2020, vacuna todos los días, sin cita previa, entre las 8.30 y las 20.30. El único requisito es ser mayor de 16 años.
En promedio, están vacunando a unas 1.500 personas por día.
Para el epidemiólogo Daniel López Acuña, “el pico epidémico de la gripe estacional de la presente temporada otoño invernal se ha adelantado casi un par de meses y llega antes de haber avanzado lo suficiente en materia de cobertura de vacunación contra la influenza”. Según él, “la cobertura vacunal de la población ha sido baja durante los últimos dos años debida a la fatiga con respecto a la vacunación, después de varios años de vacuna Covid”.
En España, el temor entre la población se potencia por la huelga de médicos que lleva tres días con los hospitales casi paralizados.
Reclaman un estatuto marco diferenciado y diseñado por ellos, que reduzca las horas de guardia y equipare su remuneración a las horas de trabajo normal.

Trump sends official notification to Congress on strikes against Iran

NEWYou can now listen to Fox News articles!
President Donald Trump on Monday sent an official notification to Congress about the U.S. strikes against Iran, in which he attempted to justify the military action in the now expanding conflict in the Middle East.
In a letter obtained by FOX News, Trump told Senate President Pro Tempore Chuck Grassley, R-Iowa, that «no U.S. ground forces were used in these strikes» and that the mission «was planned and executed in a manner designed to minimize civilian casualties, deter future attacks, and neutralize Iran’s malign activities.»
This comes after joint U.S.-Israeli strikes against Iran on Saturday as part of Operation Epic Fury, triggering a response from Tehran and a wider conflict in the region. The strikes killed the Islamic Republic’s Supreme Leader Ali Khamenei and other military leaders.

Trump wrote that it is not yet possible to know the full scope of military operations against Iran and that U.S. forces are prepared to take potential further action.
«Although the United States desires a quick and enduring peace, not possible at this time to know the full scope and duration of military operations that may be necessary,» Trump wrote. «As such, United States forces remain postured to take further action, as necessary and appropriate, to address further threats and attacks upon the United States or its allies and partners, and ensure the Government of the Islamic Republic of Iran ceases being a threat to the United States, its allies, and the international community.»
«I directed this military action consistent with my responsibility to protect Americans and United States interests both at home and abroad and in furtherance of United States national security and foreign policy interests,» he added. «I acted pursuant to my constitutional authority as Commander in Chief and Chief Executive to conduct United States foreign relations.»

Trump said he was «providing this report as part of my efforts to keep the Congress fully informed, consistent with the War Powers Resolution,» as some Republican and Democrat lawmakers attempt to restrain the president’s military action, which they affirm is unconstitutional without congressional approval.
The president also accused Iran of being among the largest state sponsors of terrorism in the world and purported that the «Iranian regime continues to seek the means to possess and employ nuclear weapons,» even after the White House said in June that precision strikes at the time «obliterated» Iran’s nuclear enrichment facilities.

«As I previously communicated to the Congress, Iran remains one of the largest, if not the largest, state-sponsors of terrorism in the world,» Trump said in the letter on Monday. «Despite the success of Operation MIDNIGHT HAMMER, the Iranian regime continues to seek the means to possess and employ nuclear weapons. Its array of ballistic, cruise, anti-ship, and other missiles pose a direct threat to and are attacking United States forces, commercial vessels, and civilians, as well as those of our allies and partners.»
«Despite my Administration’s repeated efforts to achieve a diplomatic solution to Iran’s malign behavior, the threat to the United States and its allies and partners became untenable,» he continued.

Iran nuclear talks ‘didn’t pass the smell test’ before Trump launched strikes, says Vance

NEWYou can now listen to Fox News articles!
Vice President JD Vance confirmed Monday that negotiations with Iran over its nuclear program collapsed after U.S. officials concluded Tehran’s claims «did not pass the smell test,» prompting President Donald Trump to authorize Operation Epic Fury.
Speaking on «Jesse Watters Primetime,» Vance said U.S. envoys — including Steve Witkoff, Secretary of State Marco Rubio and Jared Kushner — had conducted rounds of «deliberate» talks in Geneva with the Iranian delegation.
The discussions were aimed at curbing Tehran’s nuclear program in exchange for sanctions relief and averting a broader conflict, he said, but ultimately broke down.
«But the Iranians would come back to us and they’d say, ‘Well, you know, having enrichment for civilian purposes, for energy purposes, is a matter of national pride,’» Vance said.

«And so we would say, ‘OK, that’s interesting, but why are you building your enrichment facilities 70 feet underground? And why are you enriching to a level that’s way beyond civilian enrichment and is only useful if your goal is to build a nuclear bomb?’» he said.
«Nobody objects to the Iranians being able to build medical isotopes; the objection is these enrichment facilities that are only useful for building a nuclear weapon,» Vance clarified.
«It just doesn’t pass the smell test for you to say that you want enrichment for medical isotopes, while at the same time trying to build a facility 70 to 80 feet underground,» he explained.

Vance spoke as Operation Epic Fury ended its third day. Launched on Feb. 28, U.S. and Israeli forces carried out coordinated precision strikes deep inside Iran aimed at crippling Tehran’s missile arsenal and nuclear infrastructure.
A key issue had been Iran enriching uranium to high levels, including material around 60% purity — a fraction of weapons-grade but far above limits set under the 2015 nuclear deal — keeping international alarm high over proliferation risks.
«We destroyed Iran’s ability to build a nuclear weapon during President Trump’s term,» Vance told Watters. «We set them back substantially. But I think the President was looking for the long haul,» he said.
«Trump was looking for Iran to make a significant long-term commitment that they would never build a nuclear weapon, that they would not pursue the ability to be on the brink of a nuclear weapon.»

«He wanted to make sure that Iran could never have a nuclear weapon, and that would require fundamentally a change in mindset from the Iranian regime.»

«The President is not going to rest until he accomplishes that all-important objective of ensuring that Iran can’t have a nuclear weapon, not just for the next few years, not just because we obliterated for dough or some other.»
«There’s just no way that Donald Trump is going to allow this country to get into a multiyear conflict with no clear end in sight and no clear objective,» Vance added while describing that the administration would prefer to see «a friendly regime in Iran, a stable country, a country that’s willing to work with the United States.»
