New Delhi, 3 June (IANS). According to a study, vaccination can play an important role in preventing hearing loss (decrease in hearing ability) in children and adolescents. It identifies 26 infectious microbes that can potentially cause hearing loss.
More than 1.5 billion people worldwide are affected by the lack of ability to hear to some extent. Although it is often associated with aging, but less known but important reasons are infection occurring during childhood and adolescence, many of which can be prevented.
According to the World Health Organization, about 60 percent of hair hearing can be prevented through public health measures such as rubella and some types of meningitis.
For further investigation, a team of researchers, including Montreal University, Canada, conducted a thorough review of scientific literature.
The study published in a magazine called Communications Medicine has identified 26 infectious factors, which can potentially cause hearing loss, including viruses responsible for common diseases such as measles and rubella, which are particularly dangerous when they are infected during pregnancy as it can damage the developing hearing system and cause congenital deafness.
The list also includes a virus -causing virus -causing viruses, which can cause sensory hearing loss by damaging the inner ear or hearing nerve and also include hemophilus influenza, streptococcus pneumonia, and Nisseria meningitidis bacteria, which produce meningitis and cause permanent damage.
Meera Johri, Professor of the Department of Health Management, Evaluation and Policy at the University School of Public Health (EPSUM) said, “If it is proved that a vaccine is capable of saving life, it is appropriate to take policy decisions on that basis.”
“But the vaccines can also provide significant benefits in preventing other disadvantages, such as hearing reduction, and need to pay more attention to these benefits.”
The study recommends the inclusion of the impact of the reduction in hearing ability in the evaluation of the vaccine, whether during development or for the products already existing in the market. This factor can also help notify research preferences for new vaccine formulation.
