KONTAN.CO.ID – JAKARTA. The delta variant of Covid is one of the most contagious respiratory diseases scientists have ever seen.
This variant is highly contagious, especially because people infected with the delta strain can carry up to 1,000 times more virus in their nasal passages than those infected with the original strain, according to the latest data.
“The delta variant is more aggressive and much more infectious than the previously circulating strains,” said Centers for Disease Control and Prevention (CDC) Director Dr. Rochelle Walensky told reporters at a Thursday briefing as reported by CNBC.
“This is one of the most contagious respiratory viruses we know of, and one I have seen in my 20-year career.”

The delta variant has spread rapidly across the US, accounting for more than 83% of consecutive cases in the US today, up from 50% in the week of July 3.
The seven-day average of new cases is up about 53% from last week, currently at 37,674 new cases per day. Hospitalizations rose 32% from last week’s 3,500 per day and deaths also increased 19% in the same time period to around 240 per day.
“This virus has no incentive to stop, and keeps looking for the next susceptible person to infect,” Walensky said.
The virus strikes US states with low vaccination rates, while states with high vaccination rates experience lower rates of new cases.
