Orange County declares health emergency amid RSV spread

Rapidly spreading viral infections have pushed pediatric hospitalizations and daily emergency room visits to record levels in Orange County, prompting officials to declare a health emergency.

The county, like the rest of California, is facing a viral triple whammy: continued circulation of the coronavirus; seasonal rise of the flu; and heightened spread of respiratory syncytial virus, or RSV, a respiratory illness that can cause babies to struggle to breathe.

County health officials warned over the weekend that elevated spread of respiratory illnesses, specifically RSV, was severely impacting capacity in the region’s pediatric hospitals.

There’s also worry that the coronavirus — which has been in somewhat of a lull for weeks — could surge again this fall and winter, as has happened each of the past two years.

“While there isn’t a vaccine against RSV, we want O.C. residents to know there are many ways to protect children and at-risk individuals,” Dr. Regina Chinsio-Kwong, Orange County health officer and chief medical officer of the county Health Care Agency, said in a statement Monday night. “Following preventive measures, including remaining up to date with other vaccinations, such as flu and COVID-19, can help reduce the severity of disease and can help reduce the burden on hospitals this fall and winter.”

Chinsio-Kwong also issued a proclamation of local emergency, which would allow access to state and federal resources “to address the situation and seek mutual aid from surrounding counties,” according to the statement.

“Our best shot at protecting ourselves and our children from respiratory illnesses continues to be the same things we practiced throughout the pandemic, including the use of masks when indoors around others and staying home when you are sick,” she said.

County health officials said parents should seek immediate medical attention if their child is having trouble breathing, showing signs of dehydration, has a persistent or high fever or appears very ill. Young children with acute respiratory illnesses also should be kept out of childcare even if they have tested negative for COVID-19.

RSV is hitting many parts of the nation particularly hard, possibly because transmission has been relatively dormant for the last two years and there are many young children who have little immunity to the virus. Dr. Ashish Jha, the White House’s COVID-19 response coordinator, estimated last week that about 90% of kids end up contracting RSV at least once by the time they’re 2 years old. But “because of the pandemic, some of the kind of standard patterns have been disrupted, so we’re seeing a lot of RSV at once,” he said.

The past two influenza seasons have also been largely mild, which officials attribute in part to the infection-prevention measures implemented in response to the COVID-19 pandemic. However, the vast majority of those measures have been lifted, meaning residents now must make individual determinations regarding whether to wear a face mask or otherwise alter their behavior.

Health officials have started sounding the alarm about the triple viral threat California is facing. Heightened simultaneous spread of coronavirus, RSV and influenza, they warn, is a dangerous combination that could further stress healthcare systems in the state.

Los Angeles County officials have noted that both RSV and the flu are much more active than typical for this time of year — a development some worry could foreshadow a challenging season.

“As with the flu, we cannot predict whether this is an early peak or start to a severe season. But we do know that RSV activity is unusually high for this time of year and warrants caution,” L.A. County Public Health Director Barbara Ferrer said.

A “triple whammy of all three viruses circulating at the same time could lead to strains on the already overburdened medical system,” San Diego County health officials wrote in a statement late last week.

“As we see a sharp increase of flu and RSV cases, I am urging San Diegans to do their part to prevent the spread of illnesses,” said county Public Health Officer Dr. Wilma Wooten. “While there’s no vaccine for RSV, ample vaccinations are available for the flu and COVID-19.”

In both cases, Wooten noted that the vaccines “take two weeks to become fully effective, so people should get both shots as soon as possible.”
