COVID-19 hospitalisations, deaths in US likely to spike in next 4 weeks: CDC warns

The US Centers for Disease Control and Prevention (CDC) published ensemble forecasts on Wednesday predicting 9,600 to 33,300 new confirmed COVID-19 hospital admissions likely reported on September 6 and 3,300 to 12,600 new deaths likely reported in the week ending September 4.

The US may see a spike in COVID-19 related hospitalisations and deaths over the next four weeks, the country's public health agency has warned, driven in large part by the highly infectious Delta variant.

The US Centers for Disease Control and Prevention (CDC) published ensemble forecasts on Wednesday predicting 9,600 to 33,300 new confirmed COVID-19 hospital admissions likely reported on September 6 and 3,300 to 12,600 new deaths likely reported in the week ending September 4.

COVID-19 hospitalisations are reaching all-time highs in parts of the South in the US, with some patients unable to get the care they would normally receive, CNN reported.

Across the country, states are struggling to fend off the Delta variant -- the most contagious strain of coronavirus yet, it said.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
