Today, The New York Times reports:
The Wuhan coronavirus spreading from China is now likely to become a pandemic that circles the globe, according to many of the world’s leading infectious disease experts.
The prospect is daunting. A pandemic — an ongoing epidemic on two or more continents — may well have global consequences, despite the extraordinary travel restrictions and quarantines now imposed by China and other countries, including the United States.
Scientists do not yet know how lethal the new coronavirus is, however, so there is uncertainty about how much damage a pandemic might cause. But there is growing consensus that the pathogen is readily transmitted between humans.
The Wuhan coronavirus is spreading more like influenza, which is highly transmissible, than like its slow-moving viral cousins, SARS and MERS, scientists have found.
“It’s very, very transmissible, and it almost certainly is going to be a pandemic,” said Dr. Anthony S. Fauci, director of the National Institute of Allergy and Infectious Disease. “But will it be catastrophic? I don’t know.”
It is “increasingly unlikely that the virus can be contained,” said Dr. Thomas R. Frieden, a former director of the Centers for Disease Control and Prevention who now runs Resolve to Save Lives, a nonprofit devoted to fighting epidemics. “It is therefore likely that it will spread, as flu and other organisms do, but we still don’t know how far, wide or deadly it will be.”
One of the biggest questions about this new virus is how lethal it will be:
The biggest uncertainty now, experts said, is how many people around the world will die. SARS killed about 10 percent of those who got it, and MERS now kills about one of three.
The 1918 “Spanish flu” killed only about 2.5 percent of its victims — but because it infected so many people and medical care was much cruder then, 20 to 50 million died.
By contrast, the highly transmissible H1N1 “swine flu” pandemic of 2009 killed about 285,000, fewer than seasonal flu normally does, and had a relatively low fatality rate, estimated at .02 percent.
The mortality rate for known cases of the Wuhan coronavirus has been running about 2 percent, although that is likely to drop as more tests are done and more mild cases are found.
An accurate estimate of the virus’s lethality will not be possible until certain kinds of studies can be done: blood tests to see how many people have antibodies, household studies to learn how often it infects family members, and genetic sequencing to determine whether some strains are more dangerous than others.
Closing borders to highly infectious pathogens never succeeds completely, experts said, because all frontiers are somewhat porous. Nonetheless, closings and rigorous screening may slow the spread, which will buy time for the development of drug treatments and vaccines.
Other important unknowns include who is most at risk, whether coughing or contaminated surfaces are more likely to transmit the virus, how fast the virus can mutate and whether it will fade out when the weather warms.
However, it would appear that some doctors are having some success in treating severe cases of illness caused by the Wuhan coronavirus. Reuters reports that Thai doctors have had some success in treating patients infected with 2019-nCoV using a combination of HIV and influenza drugs:
Thai doctors have seen success in treating severe cases of the new coronavirus with combination of medications for flu and HIV, with initial results showing vast improvement 48 hours after applying the treatment, they said on Sunday.
The drug treatment includes a mixture of anti-HIV drugs lopinavir and ritonavir, in combination with flu drug oseltamivir in large doses.
The New York Times article I cited earlier says:
In China, several antiviral drugs are being prescribed. A common combination is pills containing lopinavir and ritonavir with infusions of interferon, a signaling protein that wakes up the immune system.
In the United States, the combination is sold as Kaletra by AbbVie for H.I.V. therapy, and it is relatively expensive. In India, a dozen generic makers produce the drugs at rock-bottom prices for use against H.I.V. in Africa, and their products are W.H.O.-approved.
Another option may be an experimental drug, remdesivir, on which the patent is held by Gilead. The drug has not yet been approved for use against any disease. Nonetheless, there is some evidence that it works against coronaviruses, and Gilead has donated doses to China.
Of course, it is still early days, and a great deal more testing and research needs to be done.
