Coronavirus update: First U.S. case of person-to-person transmission confirmed, 195 U.S. citizens in isolation and WHO to decide if it’s a public health emergency

A new U.S. task force led by Health and Human Services chief Alex Azar is the latest effort by officials to prepare for additional cases of the novel coronavirus in the U.S. Read More...

The Centers for Disease Control and Prevention said Thursday that it has confirmed the first U.S. case of person-to-person spread of coronavirus, among a married couple in Illinois.

There are now six confirmed cases of coronavirus in the U.S., two of which are in Chicago. The sixth case is the husband of the first confirmed case in Illinois, a woman in her 60s. He did not travel to Wuhan, China, the city that first identified the novel coronavirus, and only recently began to show symptoms of the virus.

The first U.S. residents to be diagnosed with the coronavirus had all recently traveled to Wuhan City, China. There are now 21 people under investigation in Illinois and a total of 165 under investigation in the U.S., according to the CDC.

The agency said Wednesday that 195 U.S. citizens who were flown back from Wuhan were being voluntarily isolated at March Air Reserve Base in Riverside County, California. None have tested positive for the coronavirus. The State Department said Wednesday it is planning for additional evacuation flights for private U.S. citizens around Feb. 3.

The case tally in China continues to rise. The latest figures from China’s National Health Commission say there are 7,711 cases and at least 170 people have died. There are 82 confirmed cases outside of China, according to the World Health Organization.

President Donald Trump on Thursday announced the formation of a new task force for coronavirus led by Health and Human Services chief Alex Azar. Also on Thursday, WHO’s Emergency Committee is expected to announce whether it will declare the outbreak a Public Health Emergency of International Concern.

An International Monetary Fund spokesman told reporters it’s too early to tell how the coronavirus will impact global growth. “The economic impact will depend very much on the behavior of the illness itself, how fast it spreads, who it affects, and how quickly the contagion will run its course,” Gerry Rice said.

Companies prepare investors for virus impact: The brunt of the coronavirus slowdown continues to hit retailers, travel operators and companies with a large manufacturing presence in China. Unilever PLC ULVR, +2.02% told investors to expect a commercial impact. “About a fifth of our business in China is professional food service, and that’s likely to be significantly impacted by a drop in out-of-home consumption,” Unilever CEO Alan Jope said during an earnings call. Tesla Inc. TSLA, +11.17% told investors to expect a seven-to-10 day delay on the ramp of the Model 3, which is manufactured in Shanghai, while Las Vegas Sands Corp. LVS, +0.82% said visits to Macau were down 80% as a result of the coronavirus outbreak. Macau’s operations make up 64% of the company’s total revenues. “Every segment is in decline for every property,” Las Vegas Sands president and COO Robert Goldstein said during an earnings call.

Life sciences companies disclose additional details about virus treatment plans: Illumina Inc ILMN, -4.97%, which makes sequencing equipment, said it is working with the Chinese CDC to develop next-generation sequencing (NGS) testing protocols for the Wuhan virus and expects to share those protocols with its customers. Illumina CEO Francis DeSouza told investors the company believes first-line testing of patients will be done using reverse transcription polymerase chain reaction (RT-PCR), but he believes that next-generation sequencing will be used to confirm the strain, detect mutations, and test patients with inconclusive results. “When a patient presents with suspicious symptoms, but the RT-PCR tests are negative for coronaviruses and also for other viruses with similar symptoms like influenza, then we expect an NGS test to be used,” he said. George Scangos, CEO of Vir Biotechnology Inc. VIR, +9.00% and former chief executive of BIIB, -1.61%, said Vir is testing its current antibodies are effective treatments against the virus within the next few months. The company is also in discussions with regulators and manufacturers.

U.S. health insurers likely to sidestep coronavirus hit: The outbreak isn’t expected to have a material impact on U.S. health insurers, like Anthem Inc. ANTM, -3.85% or Cigna Corp. CI, -3.57%, according to Fitch Ratings. Insurers traditionally incorporate seasonal flu-related morbidity levels in their premium rates, but those rates don’t account for a pandemic. Still, Fitch said Wednesday the Wuhan virus isn’t expected to affect insurer credit profiles any differently than SARS or MERS. The fact that the five U.S. cases are in four states also bodes well for insurers. “The appearance and transmission of the virus from several different regions could reduce the benefits of geographic diversification of membership,” the Fitch analysts wrote.
