It turns out that the flu does not need coughing or sneezing for transmission.
According to a new study, it was revealed that influenza virus, commonly known as influenza, can be transmitted through respiration, against all notions of contamination from exposure to droplets of coughs and sneezes.
A study conducted by the University of Maryland published some new tests for airborne transmission. The study, "Infectious virus in breath exhaled from cases of seasonal flu symptomatic of a university community," pointed out the large numbers of researchers of infectious viruses that are found in the breath exhaled by people suffering from the flu.
Dr. Milton, MD, MPH, professor of environmental health at the University of Maryland School of Public Health and principal investigator of this study said: "We found that influenza cases contaminated the air around them with the infectious virus only by breathing , without coughing or sneezing "
He added:" "People with the flu generate infectious aerosols (small drops that remain suspended in the air for a long time) even when they are not coughing, and especially during the first days of the illness. Then, when someone gets the flu, they should go home and not stay in the workplace and infect others. "
Researchers from San Jose State University, the University of Maryland, the University of California – Berkeley and Western State University of Missouri contributed to this study that was funded by the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health.
The team captured and studied the influenza virus in exhaled breath from 142 confirmed cases of people with influenza during natural respiration, induced speech, spontaneous coughing and sneezing, and infectivity of naturally occurring influenza aerosols were evaluated.
Participants provided 218 samples of 30 minutes of exhaled breath, cough spontaneous and sneezing, and 218 nasopharyngeal swabs in the first, second, and three days after the onset of symptoms.
The infectious virus showed that a significant number of patients with flu routinely The results of the study suggest that keeping surfaces clean, washing hands all the time, and avoiding people coughing does not. provide complete protection against influenza, "said Sheryl Ehrman, Don Beall Dean of the Charles W. Davidson School of Engineering at San Jose State University, adding that" staying home and leaving public spaces could make a difference in the spread of influenza virus. "
According to the authors, the findings could be used to improve mathematical models of the risk of airborne influenza transmission in people with symptomatic disease. more effective public health and control and reduce the impact of influenza and pandemic epidemics.
They also noted that improvements could be made to ventilation systems to reduce the risk of transmission in public places such as offices, schools, classrooms, and wagons. The study suggested vaccination, although it is not perfect, but it prevents a significant amount of disease. ave.
