Coronavirus updates: Johnson & Johnson pauses vaccine trial
The company is currently in Phase 3 of its trial.
A pandemic of the novel coronavirus has now killed more than 1 million people worldwide.
Over 37.6 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The criteria for diagnosis -- through clinical means or a lab test -- has varied from country-to-country. Still, the actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.
Since the first cases were detected in China in December, the virus has rapidly spread to every continent except Antarctica.
The United States is the worst-affected country, with more than 7.7 million diagnosed cases and at least 214,771 deaths.
California has the most cases of any U.S. state, with more than 855,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 818,000 cases and over 736,000 cases, respectively.
More than 190 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least 10 of which are in crucial phase three studies. Of those 10 potential vaccines in late-stage trials, there are currently five that will be available in the United States if approved.

US reports more than 44,000 new cases
There were 44,614 new cases of COVID-19 identified in the United States on Sunday, according to a real-time count kept by Johns Hopkins University.
The latest daily tally is down by more than 10,000 from the previous day and falls well under the country’s record set on July 16, when there were 77,255 new cases in a 24-hour-reporting period.
An additional 400 coronavirus-related fatalities were also recorded Sunday, down from a peak of 2,666 new fatalities reported on April 17.
A total of 7,762,809 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 214,771 of them have died, according to Johns Hopkins. The cases include people from all 50 U.S. states, Washington, D.C. and other U.S. territories as well as repatriated citizens.
By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 70,000 for the first time in mid-July. The daily tally of new cases has gradually come down since then but has started to climb again in recent weeks.
Week-over-week comparisons show the number of new cases reported across the nation continues to go up, as does the usage of intensive care units, but the number of new deaths are down, according to an internal memo from the U.S. Department of Health and Human Services that was obtained by ABC News last week.
Mexico confirms 1st case of someone with both COVID-19 and influenza
Mexico has confirmed its first case of an individual who has tested positive for both COVID-19 and influenza at the same time.
Dr. Jose Luis Alomia Zegarra, director general of epidemiology at the Mexican Ministry of Health, told a press conference Sunday night that the case was detected in a 54-year-old woman with a number of preexisting conditions who remains hospitalized in stable condition after developing COVID-19 symptoms. She's a cancer survivor and suffers from autoimmune disease, chronic pulmonary issues as well as obesity, according to Zegarra.
Zegarra said the woman first displayed symptoms of COVID-19 at the end of September and was hospitalized. She tested positive for COVID-19 on Oct. 2 as she awaited the results of a panel of over a dozen viral exams. The patient started to receive therapy for COVID-19 and was later discharged from the hospital between Oct. 5 and Oct. 6 after her condition improved.
On Oct. 8, while at home, the woman started to have a fever and respiratory issues again. She was admitted to the hospital a second time, according to Zegarra.
On Saturday, the patient's full virus panel test returned with positive results for both COVID-19 and influenza, Zegarra said.
Since the start of the pandemic, Mexico's health ministry has confirmed more than 817,000 cases of COVID-19 with at least 83,781 deaths. The country has the four-highest death toll from COVID-19 in the world, according to tallies kept by Johns Hopkins University.
