New Study Reports that Flu can be Spread without Cough and Sneeze
A study published in the Proceedings of the National Academy of Sciences reports on January 18, 2017 that influenza virus can be easily spread without cough and sneeze.
Influenza is believed to be transmitted from infected individuals through coughing or sneezing latest research suggests that there could be various modes for viral infection. Seasonal influenza is an acute viral infection characterized by a sudden onset of fever, cough, headache, muscle and joint pain, sore throat and a runny nose.
Although most of the patients recover within a week without requiring medical attention, the influenza virus can result in severe illness and death in high risk populations, such as the very young and the elderly. Researchers at the University Of Maryland School Of Public Health conducted a study to investigate 142 patients who confirmed infection with the influenza virus. A total of 218 nasopharyngeal swabs and 218 samples of exhaled breath, spontaneous coughing, and sneezing collected on the first, second, and third day after the onset of symptoms were analyzed.
Almost half of the samples collected during normal breathing contained viral RNA and almost 73% also contained infectious virus. Results of the study suggests that infectious virus can be released into the air by an infected patient even when they are not coughing. Furthermore, sneezing was found to not make an important contribution to influenza virus shedding in aerosols. This new research thus provides evidence for the increased potential of airborne transmission of the influenza virus. Researchers believe that findings could be used to more accurately describe the risk of airborne influenza transmission from people with symptomatic illness and to develop more effective public health interventions.
According to Influenza Vaccines Market report published by Coherent Market Insights, influenza is an infection is commonly known as flu. Vaccination for influenza aids in prevention of flu. Results of the study show could help to control influenza epidemics and pandemics. In the short term, people are recommended to stay home if they start to develop symptoms of influenza.
