The line between truth and lies is becoming ever murkier. It’s possible the virus sticks around in the body longer than expected, because patients still testing positive for the virus after they have recovered or even getting sick again.
People who appear to recover and then show symptoms again may have suffered a relapse of the same infection. Patients produced thousands to millions of viruses in their noses and throats, about 1,000 times as much virus as produced in SARS patients, that heavy load of viruses may help explain why the new coronavirus is so infectious.
If antibodies cannot be detected, it is because viruses are constantly replicating and antibodies are generated to neutralize them. Otherwise, it indicates viruses have been deactivated.
For most people, medicine treatment can't cure chronic hepatitis B, only suppressing the replication of the virus. Therefore, most people who start treatment must continue it for life.
Based on experience from SARS and MERS and AIDS, virus covid- 19 stay in human body permanent. On patients after they have recovered the researchers could still detect the virus’s genetic material, RNA, in patients’ swabs or samples, but could no longer find infectious viruses.
That’s an indication that antibodies that the body’s immune system makes against SARS-CoV-2 are killing viruses that get out of cells.
US Secretary of State Mike Pompeo said Sunday there was "enormous evidence" that the coronavirus pandemic originated in a laboratory in Wuhan, China, echoing a claim made by President Donald Trump earlier this week. "There is enormous evidence that this is where it began," the US secretary of state said on ABC's "This Week."
ReplyDelete"These are not the first times that we've had a world exposed to viruses as a result of failures in a Chinese lab," Pompeo added, pointing at China's "history of running substandard laboratories."
Though highly critical of China's handling of the matter, Pompeo declined to say whether he thought the virus had been intentionally released.
Speaking at the White House on Thursday, Trump also claimed he had seen evidence that the virus originated in a Chinese lab, ratcheting up tensions with Beijing over the origins of the deadly outbreak.
"Yes, yes I have," Trump said when asked if he had seen evidence that gave him a "high degree of confidence" the virus came from the Wuhan Institute of Virology.
The US president declined to give specifics, adding: "I can't tell you that. I'm not allowed to tell you that." The Chinese state-backed Wuhan Institute of Virology has dismissed the allegations, and other US officials have downplayed their likelihood. Most experts believe the virus originated in a market selling wildlife in Wuhan and jumped from animals to people.
Pompeo himself had appeared to cast doubt on Trump's claims, stating on Thursday that it was not known whether the virus came from the lab. "We don’t know if it came from the Wuhan Institute of Virology. We don’t know if it emanated from the wet market or yet some other place. We don’t know those answers," Pompeo said in an interview with Newsradio 1040.
The spread of the coronavirus, which causes the respiratory disease Covid-19, has contributed to a deepening rift between the Trump administration and China.
Beijing has suggested the US military might have brought the virus to China and Trump has said China failed to alert the world to the risks in a timely and transparent fashion.
Trump also said on Thursday it was possible that China either could not stop the spread of the coronavirus or allowed it to spread.
People dying of COVID-19 could have expected to live on average for at least another decade, according to two studies that help fill in the developing picture of the human cost of the coronavirus pandemic.
ReplyDeleteThe findings show the virus isn’t just carrying off the elderly or infirm a few months before their time.
“Some people think that these people dying would have died this year anyway,” said Andrew Briggs, a professor of health economics at the London School of Hygiene & Tropical Medicine who led one of the studies. “That’s simply not the case.”
As governments loosen lockdowns that have contained the disease but cratered economies, estimates of life-years lost can feed into initial assessments comparing the costs of the shutdowns against the social and economic benefits of saving lives. Such cost-benefit studies, while coldly analytical, are a standard tool used by public health services, insurers and pharmaceutical companies.
Some scientists said the new studies reinforced the argument that social distancing and other methods of preventing transmission should remain a feature of everyday life to prevent a resurgence of the coronavirus.
The two academic analyses, published separately, examined mortality data in several hard-hit countries to compare the age at which victims of COVID-19, the disease caused by the virus, are dying with data on life expectancy overall. The studies, using different techniques, took account of differences in life expectancy associated with common ailments, such as heart disease, diabetes and dementia, to reflect varying levels of health of those who died.
