Although almost no one has talked about it for four years due to the Covid-19 outbreak, the fact is Influenza still kills every year.only in activities 2019/2020the Influenza Surveillance System of the Carlos III Health Institute attributes the virus to some 3,900 deaths.
as pointed out Dr. Estanislao Nistar VeranDirector of the Virology and Innate Immunity Research Group at CEU San Pablo University (USPCEU).
“Although we are already familiar with the word influenza, this disease kills more people in Spain than traffic accidents.”
Therefore, many researchers are interested in understanding Factors that aggravate this pathology during the annual flu season.
In this sense, this is the conclusion of a study published in the International Journal of Infectious Diseases, coordinated by the USPCEU and in collaboration with the Immunology and Transplantation Unit of the National Microbiology Center of the Carlos III Institute of Health (ISCIII) Yes, this year:
To come to this conclusion, researchers Data from more than 48,000 patients analyzed Published between 2010 and 2020, from 135 studies in 28 countrieslooking for the main causes of increased flu severity.
The results indicate that bacterial lung infection is one of the most relevant risk factors for influenza virus infection.
As they detail Javier Arranz-Herrero and Jesus Presafirst author of the study:
“Some of the bacteria that cause these secondary pneumonias can live inside our bodies and colonize our upper respiratory systems or infect us from the outside. The most common are, e.g. Streptococcus pneumoniae
and Staphylococcus aureusyes It is responsible for more than 60% of influenza-related bacterial pneumonias“.he Dr. Estanislao Nistar VeranThe USPCEU Director noted that the analysis yielded particularly interesting data, e.g. The combination of influenza and bacterial lung infection more than triples the risk of death.
Therefore, researchers insist that it is necessary Develop preventive, diagnostic and antibiotic treatment strategies in high-risk situations Complications associated with influenza infection.
In addition to this type of pneumonia, researchers Other illnesses have been found to increase the risk of death when coinfected with influenzabetween them:
One of the curious things about this study is that it raises the question of whether a large proportion of the deaths (about 50 million people) were caused by the so-called “Spanish flu” pandemic. In the early 20th century, it was likely due to bacterial infections associated with cases of influenza.
Obviously, the results show Improving outcomes for patients with influenza infection is key:
The researchers also note that the current COVID 19 crisis highlights the urgent need to develop new strategies to improve our health systems to identify and reduce specific risks.
this Children and the elderly are most at risk People who have complications from the flu:
“This work attempts to use concrete values to highlight weaknesses that must be taken into account Better care for the flu”the study’s authors concluded.
