How dangerous is the virus?
There are three parameters to understand in order to assess the magnitude of the risk posed by this novel coronavirus:
- Transmission Rate (Ro) – number of newly infected people from a single case
- Case Fatality Rate (CFR) – percent of cases that result in death
- Determine whether asymptomatic transmission is possible
How contagious is the Wuhan Coronavirus? (Ro)
The attack rate or transmissibility (how rapidly the disease spreads) of a virus is indicated by its reproductive number (Ro, pronounced R-nougat or r-zero), which represents the average number of people to which a single infected person will transmit the virus.
WHO’s estimated (on Jan. 23) Ro to be between 1.4 and 2.5Other studies have estimated a Ro between 3.6 and 4.0, and between 2.24 to 3.58Preliminary studies had estimated Ro to be between 1.5 and 3.5An outbreak with a reproductive number of below 1 will gradually disappear.
For comparison, the Ro for the common flu is 1.3 and for SARS it was 2.0.
Age and conditions of Coronavirus cases
Age, Sex, Demographics of COVID-19 Cases and Deaths
According to early estimates by China’s National Health Commission (NHC), about 80% of those who died were over the age of 60 and 75% of them had pre-existing health conditions such as cardiovascular diseases and diabetes. According to the WHO Situation Report no. 7 issued on Jan. 27:
- The median age of cases detected outside of China is 45 years, ranging from 2 to 74 years.
- 71% of cases were male.
A study of 138 hospitalized patients with NCIP found that the median age was 56 years (interquartile range, 42-68; range, 22-92 years) and 75 (54.3%) were men.
The WHO, in its Myth busters FAQs, addresses the question: “Does the new coronavirus affect older people, or are younger people also susceptible?” by answering that:
- People of all ages can be infected by the novel coronavirus COVID-19.
- Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus.
199 Countries and Territories around the world have reported a total of 549,430 confirmed cases of the coronavirus COVID-19 that originated from Wuhan, China, and a death toll of 24,872 deaths.
The number of confirmed COVID-19 cases in Pakistan rose to 1,238 on Friday after more people tested positive in Sindh, Khyber Pakhtunkhwa and Islamabad Capital Territory.
The U.S. death toll from the coronavirus has hit 1,000, according to tracking by The Washington Post, a toll that is increasing at an alarming rate. The United States also surpassed China in confirmed, reported cases Thursday as the pandemic continues to slow in the place where it began. Worldwide, the number of confirmed coronavirus cases surpassed 500,000.
Here are some significant developments:
- The $2 trillion emergency relief bill passed by the Senate will be voted on Friday by the House, said Speaker Nancy Pelosi (D-Calif.), who predicted the measure would receive “strong bipartisan support,” but not unanimous consent. Rep. Thomas Massie (R-Ky.), who opposes the bill, said Thursday that he is considering a procedural move that could delay passage of the bill to Saturday or Sunday.
- Deborah Birx, the White House response coordinator, sought to calm frightened Americans Thursday by downplaying the worst-case statistics, while doctors at the hardest hit hospitals warn there are not enough supplies, beds or physicians to handle the surge in patients.
- The USNS Comfort, a Navy hospital ship, will leave Norfolk, Va., for New York City on Saturday — at least three weeks ahead of schedule. The New York City area is the current U.S. epicenter, but the number of confirmed cases is beginning to spike elsewhere, including Louisiana, Michigan and Texas.
- New York is moving at unprecedented speed and scale to distribute tens of thousands of doses of antimalarial drugs to seriously ill patients, spurred by political leaders, including President Trump, to try a treatment that is not yet proved to be effective.
- The Labor Department’s weekly tally of 3.3 million jobless claims shattered the old U.S. record of 695,000, set in 1982. Of the “widespread carnage,” an economist at the University of Illinois at Chicago warned: “It’s going to get worse.”
- During a meeting of the Group of 20 nations, U.N. Secretary General AntónioGuterres reminded the leaders of the exponential spread of the virus, saying the first 100,000 cases were confirmed in the first three months of the outbreak. “The next 100,000 happened in just 12 days,” he said. “The third took four days. The fourth, just one-and-a-half.”
