US cases of the novel coronavirus were approaching 6 million on Sunday as many Midwest states reported increasing infections, according to a Reuters tally.

Iowa, North Dakota, South Dakota and Minnesota have recently reported record one-day increases in new cases while Montana and Idaho are seeing record numbers of currently hospitalized COVID-19 patients.

Nationally, metrics on new cases, deaths, hospitalizations and the positivity rates of tests are all declining but there are emerging hotspots in the Midwest.

Many of the new cases in Iowa are in the counties that are home to the University of Iowa and Iowa State University, which are holding some in-person classes. Colleges and universities around the country have seen outbreaks after students returned to campus, forcing some to switch to online-only learning.

Infections have also risen after an annual motorcycle rally in Sturgis, South Dakota drew more than 365,000 people from across the country from August 7 to 16. The South Dakota health department said 88 cases have been traced to the rally.

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.

More than eight months into the pandemic, the United States continues to struggle with testing, seeing the number of people tested fall in recent weeks.

Many health officials and at least 33 states have rejected the new COVID-19 testing guidance issued by the Trump administration last week that said those exposed to the virus and without symptoms may not need testing.

Public health officials believe the United States needs to test more frequently to find asymptomatic COVID-19 carriers to slow the spread of the disease.

While the United States has the most recorded infections in the world, it ranks tenth based on cases per capita, with Brazil, Peru and Chile having higher rates of infection, according to a Reuters tally.

The United States also has the most deaths in the world at over 182,000 and ranks 11th for deaths per capita, exceeded by Sweden, Brazil, Italy, Chile, Spain, the United Kingdom, Belgium and Peru.
