The pandemic is still a clear and present danger to everyone especially to children after the Corona virus has evolved to a Delta variant. The Delta variant is known to be more contagious than the previous variants and affecting unvaccinated people more. Lockdowns are still being enforced hoping that the spread of the virus will delay.
What is the Delta Variant
According to an article from UC Davis Health, it is a newer strain of COVID-19 is causing concern as cases are rising worldwide. The Delta variant, which originated in India, began spreading more rapidly and making news around the middle of June. Now, health experts are warning of another surger of COVID-19.
So what do we know about this Delta variant? So far, here's what the Centers for Disease Control and Prevention (CDC) has say:
- Aside from being highly contagious than the previous variants, some data suggest that the Delta variant cause more severe illness than previous strains in unvaccinated persons. In two different studies from Canada and Scotland, patients infected with the Delta variant were more likely to be hospitalized than patients infected with Alpha or the original virus strains.
- Unvaccinated people remain the greatest concern: Although breakthrough infections happen much less often than infections in unvaccinated people, individuals infected with the Delta variant, including fully vaccinated people with symptomatic breakthrough infections, can transmit it to others. CDC is continuing to assess data on whether fully vaccinated people with asymptomatic breakthrough infections can transmit. However, the greatest risk of transmission is among unvaccinated people who are much more likely to contract, and therefore transmit the virus.
- Fully vaccinated people with Delta variant breakthrough infections can spread the virus to others. However, vaccinated people appear to be infectious for a shorter period: Previous variants typically produced less virus in the body of infected fully vaccinated people (breakthrough infections) than in unvaccinated people. In contrast, the Delta variant seems to produce the same high amount of virus in both unvaccinated and fully vaccinated people. However, like other variants, the amount of virus produced by Delta breakthrough infections in fully vaccinated people also goes down faster than infections in unvaccinated people. This means fully vaccinated people are likely infectious for less time than unvaccinated people.
