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.
DataTicker – Covid 19 Global and US
These 22 charts and graphics lay out what you need to know as the outbreak continues to progress.
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 probably still higher than the official total, since some mild and asymptomatic cases are likely not tested and counted.
As the number of new reported cases in China has decreased, other countries have begun to experience surges.
Italy’s coronavirus outbreak is among the worst in the world. Its death toll surpassed China’s on March 19, and its confirmed case count surpassed China on March 27.
Countries’ coronavirus death rates vary widely right now and change constantly. Here’s what the range looked like as of March 27.
Italy has the highest number of deaths of any country in the world.
The US has reported more than 270,000 coronavirus cases — the most in the world.
At least 6,800 people in the US have died as of Friday.
The US outbreak appears to be getting worse over time — its epidemic growth curve looks like a steep staircase, with each day bringing a new record number of new confirmed cases.
New York has 44% of the US’s total cases as of Friday. Here’s how quickly New York City’s outbreak has grown.
About 90% of all Americans have been ordered to stay at home in an effort to slow the spread of the virus.
Thirty-eight states, along with Puerto Rico and Washington DC, have issued stay-at-home orders, as have some metro areas in states without such policies.
But social distancing efforts across the US haven’t been consistent.
The map above is based on an analysis by Unacast, a location data and analytics firm based in New York. It calculated changes in the average distance traveled by residents before and after the coronavirus outbreak grew in the US, using aggregated data from tens of millions of anonymous mobile phones whose users had opted in to location sharing.
There are various kinds of reduced social contact — here’s the difference between social distancing, quarantines, and self-isolation.
The goal of social distancing and other preventative measures is to keep the outbreak within the capacity of the US healthcare system. Otherwise, facilities and staff are at risk of being overrun.
Pleas to help “flatten the curve” are becoming common as the US looks for ways to curb the spread of the virus.
The coronavirus typically spreads via airborne droplets from an infected person’s coughs or sneezes. Live coronavirus particles can survive for a time on surfaces.
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 it can decrease with strong preventive measures.
The coronavirus most seriously affects older people. The chart below shows the death rates among different age groups in China.
The disease’s death rate is highest among the elderly. The study this data comes from – done by the Chinese Centers for Disease Control – did not report any deaths in children younger than 10, who represented less than 1% of the patients studied.
Death rates in the US follow a similar trend, though they are so far lower overall than in China.
The coronavirus also poses a higher risk to people with preexisting health conditions, such as diabetes, heart disease, and high blood pressure.
Among coronavirus patients, the preexisting condition with the highest death rate appears to be heart disease. Patients already diagnosed with heart disease had a death rate of more than 10% in the Chinese CDC study. Diabetes was the preexisting condition with the second-highest fatality rate: 7%.
The coronavirus is far more deadly than the flu.
That’s even true in South Korea, which so far has a lower overall coronavirus death rate than other countries (including the US) and than the global average.
The coronavirus’ pneumonia-like symptoms include fever and difficulty breathing. Some symptoms overlap with those of the common cold, allergies, and the flu, which can make it tricky to diagnose without a test.
The coronavirus primarily affects the lungs and commonly causes a fever, a dry cough, and shortness of breath. Just over 80% of coronavirus cases are “mild,” according to the analysis from the Chinese CDC.
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.
Here’s how the total number of cases and deaths from the novel coronavirus compares to other disease outbreaks.
As of Wednesday, this is how the death toll compared to that of other pandemics.
