As the world is currently facing a huge drop in daily coronavirus cases, many states have already started the unlock down process. However, experts warn that with the onset of these easing of restrictions around the world, there could be a resurgence of childhood respiratory viruses. According to reports, cases of respiratory syncytial virus (RSV) have risen sharply in Australia and, more recently, public health measures have been eased in the form of a pandemic in the US.
RSV affects the lower respiratory tract and can cause severe illness and death. Before the COVID-19 pandemic, approximately 2.7 million children worldwide were infected with RSV each year, and it was the fourth most common cause of death among young children. “The off-season resurgence in seasonal respiratory viruses now poses a threat to potentially vulnerable infants,” said Dr. Pascal Lavoie, BC Children’s Hospital Research Institute and the University of British Columbia, Vancouver.
During the COVID-19 pandemic, Canada, like other countries, has seen very few cases of RSV, with only 239 positive cases between August 29, 2020 and May 8, 2021, up from 18,860 positive tests in the same period last year. in comparison. (between 25 August 2019 to 2 May 2020). The virus seemed to have disappeared in the past year. However, an increased number of RSV cases in Canada this summer, as in other jurisdictions, could strain health care resources in pediatric intensive care units (ICUs).
While influenza and other non-Covid respiratory virus levels in the US were at historic lows during most of 2020, the virus causing the common cold is seeing a resurgence out-of-season in 2021, according to a new report from the Centers for Disease Control. and prevention (CDC).
