As the world's coronavirus case total and death toll continue to climb, a growing collection of data and research is providing insights into the pandemic.

These 32 charts and graphics lay out what to know.

Here's where cases and deaths have been confirmed around the world so far.

 

 

This chart shows the rate at which the coronavirus case total has shot up worldwide.

The true number of infected people is almost certainly higher than the official total, since many mild and asymptomatic cases are not tested and counted.  

As the number of new reported cases in China decreased, other countries experienced surges.

As of Friday, Spain, Belgium, and the US had the most cases per capita.

Italy's coronavirus outbreak is still among the worst in the world. More than 32,600 people have died there.

 

The US has reported more than 1.59 million coronavirus cases — the most in the world.

More than 95,000 people in the US have died as of Friday.

The US's epidemic has grown dramatically since the end of January.

 

New York has the largest coronavirus outbreaks in the US. Here's how the state's daily case totals have progressed.

 

As of Tuesday, this was the case breakdown by age in New York City.

From April 9 to 15, more than 13,000 people in the US died from COVID-19, surpassing the nearly 12,500 people killed on average each week in 2018 by heart conditions and the 11,500 people killed by cancer.

Far too many patients hospitalized with COVID-19 in the US are black: A CDC report found that 33% of the US's COVID-19 hospitalizations in March were black patients, though black people make up 18% of the overall US population.

"We do not think people of color are biologically or genetically disposed to get COVID-19," US Surgeon General Dr. Jerome Adams said last month. Rather, he added, black Americans "have a higher incidence of the very diseases that put you at risk for severe complications from coronavirus."

The disparity is even more stark in Georgia, where 83% of people hospitalized with COVID-19 in the state during March were black.

"When you're in the middle of a crisis, like we are now with the coronavirus, it really does, ultimately, shine a very bright light on some of the real weaknesses and foibles in our society," Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said in April

He added, "we will get over coronavirus — but there will still be health disparities which we really do need to address in the African American community."

Most US states are easing stay-at-home orders and allowing certain businesses to reopen.

The pandemic and the lockdowns implemented to fight it have taken a heavy toll on the economy. Job losses since February have been far deeper than in any other US recession since the Great Depression, with over 20 million jobs lost in April alone.

The goal of lockdowns and travel restrictions is to slow the virus' spread and promote social distancing in order to keep the outbreak within the capacity of healthcare systems.

An average coronavirus patient infects 2 to 2.5 others.

COVID-19 is more contagious than the seasonal flu. However, the R0 isn't fixed and can decrease with strong preventive measures.

The only way to figure out the extent of the coronavirus' spread is to test for it, but federal delays in rolling out COVID-19 testing in the US initially made it hard to track where new cases were spreading.

Here's how a CDC coronavirus swab test works.

Antibody tests can tell you whether you've ever been infected with the coronavirus, but their accuracy varies widely, and what a positive result actually means depends on several factors.

Even very good tests can deliver a lot of false-positive results if the coronavirus hasn't spread much in a particular area. This chart shows the positive predictive value — the likelihood that a positive test actually means you were infected — based on the underlying prevalence of the disease. Even a test that's 95% accurate is only a little better than a coin flip if less than 10% of the population was infected.

The coronavirus typically spreads via airborne droplets from an infected person's coughs, speech, or sneezes. Masks can help stymie the virus' spread.

Here's a breakdown of all the different types of face masks and who should — and shouldn't — be wearing them.

The coronavirus' pneumonia-like symptoms include fever and difficulty breathing.

The coronavirus generally affects the lungs and commonly causes a fever and dry cough. Around 20% of patients develop shortness of breath, which doctors recognize as one of the most concerning symptoms. Other symptoms include fatigue, body aches, swollen toes, a sore throat, and gastrointestinal issues.

Some symptoms overlap with those of the common cold, allergies, and the flu, which can make it tricky to diagnose without a test.

Scientists have found that the virus' average incubation period — the length of time between when a person gets infected and when they test positive for the illness — is five days. About 97% of people who get infected develop symptoms within 11.5 days. About 1% of patients, however, show symptoms after 14 days — outside the window of the CDC's quarantine guidelines.

Overall, the coronavirus is far more deadly than the flu.

covid 19 death rates per country

A death rate, or case fatality rate, is the number of known deaths out of the total number of confirmed cases. But it doesn't tell the full story, since it depends on how many cases are confirmed by tests. In general, the more cases get included in the data — including people with mild or no symptoms — the lower the death rate.

A study from the University of Washington estimated that, if all infections were known, the true death rate for Americans who show symptoms would be about 1.3%.

The coronavirus most seriously affects older people. The chart below shows the death rates among different age groups in the US.

The coronavirus also poses a higher risk to people with preexisting health conditions, such as diabetes, heart disease, and high blood pressure.

A study from the Chinese CDC found that among coronavirus patients, the preexisting condition with the highest death rate was heart disease. 

Here's how the total number of cases and deaths from the coronavirus compares to other disease outbreaks.

 

As of Friday, this is how the death toll compares to that of other pandemics.
