The practice of professional and critical journalism is a mainstay of democracy. That is why it bothers those who believe that they are the owners of the truth.
The flu that causes high positivity rates And strong demand for medical care This is a variant with mutations in the outer capsid that make this possible escape immunity both the body’s own and those produced by vaccines.
The virus’s genetic changes increased its infectious potential, especially in closed and poorly ventilated spaces. In parallel a simultaneous circulation of other respiratory viruseswhich made the situation in hospitals and medical centers even more complex.
Symptoms of the H2N2 flu variant
High fever, severe malaise, muscle pain, dry cough And fatigue are the most common symptoms of the H3N2 subclass K variant. Doctors warned that the symptoms of this flu could be confused with those of the flu COVID-19so they suggested doing it combined tests to arrive at an objective diagnosis.
Yes OK The variant has not been proven to cause more severe symptomsThe health authorities of the affected countries are concerned about their rapid spreadamid fears that the situation will trigger a collapse of health systems.
The governments of the various countries where the variant is circulating have already activated it Emergency protocols These included the reinforcement of campus grounds, isolation zones, mandatory use of masks in hospitals and prevention campaigns.
Some specialists also emphasized the importance of Vaccinationto ensure that this is an important point to reduce hospitalizations, prevent deaths and avoid health complications.
Can it reach Argentina?
The doctor Martha Cohena pediatric pathologist, warned of the increase in infections in Europe, claiming that there have already been 2,000 hospitalizations in the UK, a number that could soon rise to 8,000. “Vaccination is recommended for people over 50 years of age and with any type of immune deficiency,” he recommended.
“This will certainly arrive in Argentina in the fallThat’s why early vaccination, which is planned for March, is important. “If someone comes to Europe, get vaccinated two weeks before traveling,” he warned.

To prevent a further increase in cases, PAHO urged countries to do so Strengthen surveillance of influenza, RSV and SARS-CoV-2which implies:
-Continuous data reporting
-Regular sending of samples for genetic sequencing
-Update national clinical management guidelines
-Early diagnoses and availability of antiviral drugs
-Reinforce the importance of vaccination against influenza, COVID-19 and RSV
-Investigate and report unusual respiratory events
