The number of new admissions started to climb in early July, similar to other age groups.

According to the CDC, the Delta variant is more than twice as contagious as other variants.

As a result, many states eased or eliminated their mask requirements.

There is also the issue of coinfections, Oliveira says.

However, the recent relaxation of COVID-19 interventions may have reversed this trend.

Ineligibility for Vaccination

Getting vaccinated is the best course of action to protect against severe COVID-19 disease.

Children younger than 12 years of age are not eligible for vaccination, placing them at risk.

Some were concerned about its safety and efficacy, while others believed that children dont need to get vaccinated.

Children are certainly susceptible to the virus, Oliveira says.

So, COVID-19 is definitely bad for kids.

Why COVID-19 presents differently among children and adults is still unclear.

However, there are several theories why this is the case.

Pre-existing immunity is also a likely contributor, Oliveira says.

However, since COVID-19 is a novel virus, no one has pre-existing immunity.

The key message is that if you are eligible to be vaccinated, get that vaccine today.
