EP – Spanish Society for Critical Intensive Medicine and Coronary Unit (SEMICYUC) has warned that, according to "information currently considered", the influenza virus, which circulates mainly in Spain, is Type A, which increases the likelihood that more patients need hospitalization and more often in patients with complex viral pneumonia.

Both the pandemic virus, A (H1N1) pdm09, and the epidemic virus or A (H3N2) belong to Type A and "from previous years' experience of A (H1N1) pdm09 circulation, are more likely to appear in more patients who need to be treated. hospitalization, and more often in patients with complex viral pneumonia who need to enter intensive care units to receive supportive treatment, and in many cases artificial respiration, ”they have pointed out from SEMICYUC.

Although the majority of patients suffering from influenza every winter have mild symptoms and healed without problems, a minority of patients have complications. The main percentage of 90 percent is breathing. Images range from bronchitis to pneumonia more or less severely.

In addition, the percentage of 2 to 3 percent of patients enrolled in ICU was signs and symptoms consistent with severe meningitis or encephalitis with severe prognosis, showing a group of serious SEMICYUC influenza data.

The negative effects of influenza virus infection, especially if it is of type A (H1N1) pdm09, are caused by relieving patients with chronic diseases and the elderly. SEMICYUC has stressed the importance of vaccinating the majority of the population to prevent this type of death, that although they are not frequent, they are very impressive and require us to reflect on the need for vaccination for all citizens regardless of age. or known risk factors.

In this context, the company has reported that it has opened a GETGAG influenza influenza record for its Spanish working group A influenza tomb, launched in 2009. It provides important information on the epidemiology of this disease, as well as factors for prognosis and treatment effects on the most serious populations. It is planned that IU can report cases of this new flu season.

"In 2009, when the World Health Organization established a pandemic, SEMICYUC set up its own working group for monitoring and investigating influenza. Since then, more than 4000 patients have been registered in the GETGAG database. to make periodic reports and monitor how each winter period develops in relation to the type of patient and their severity ”, co-ordinator of this group, SEMICYUC, Dr. Alejandro Rodríguez.


All national level units follow specific protocols for the treatment and management of SEMICYUC-induced flu complications patients since 2009 and are supported by the Ministry of Health, Consumption and Social Welfare.

"Since the outbreak of the pandemic, intensive medical services have played a transcendental role in the treatment of major influenza cases in 2009. Opportunity to provide advanced respiratory support and in many cases to use complex extracorporeal oxygen systems allows us to save a large number of seriously ill patients from almost certain fatal complications," Dr. Rodríguez.

However, two out of ten patients die of ICU complications. "One of the possible causes of this mortality may be due to a delay in diagnosis caused by late consultation with patients," the expert said.

"According to the data we collected in the Spanish working group on serious SEMICYUC influenza, the average time elapsed between the onset of symptoms and counseling with a primary care physician or emergency is 4 or 5 days, time is too long for treatment to be the best. benefits, ”said Dr. Rodríguez.

The expert has advised the company that in the winter period before flu symptoms lasting more than 24 or 48 hours, a family doctor should be consulted so that the specialist assesses the need or not to perform a specific test or hospitalization in accordance with the clinical condition of each patient.


SEMICYUC has emphasized that the annual flu vaccine is "the main and best way to prevent the disease" and has stated that "it has been shown to reduce the risk of flu, hospitalization and even death for children." A child who is six months or older must "receive the vaccine every year" and must be vaccinated with the child's caregiver.

The public has also encouraged daily preventive measures such as staying away from sick people; avoid contact with other people if symptoms have already been detected; cover your nose and mouth when you cough or sneeze; wash your hands frequently; Do not touch your eyes, nose or mouth and clean and disinfect the most common contact surfaces, especially if someone is ill.

SEMICYUC has reminded that antiviral medicines are available to treat flu in children and adults, and can reduce the severity of the disease and shorten its duration by further eliminating serious complications.

"They are more effective if treatment is started within two days after the disease, although they start to use them later, but may be useful, especially if the patient has a serious illness or has a serious risk of serious complications," they said. intense.

"Treatment with antiviral drugs for people who are very ill or who have a high risk of flu complications can mean a difference between a mild disease and a very serious illness that can lead to hospitalization," he stressed. also recommends Centers for Disease Control.

ICU preventive measures with the greatest impact are from staff vaccination and early detection of the most serious patients who will require admission to intensive care units, isolation measures, and rapid detection of this virus along with the beginning of antiviral therapy.
