As US reopens, COVID-19 cases hit new high; Trump administration downplays

New Delhi, Mar 24: Reports of a person in China dying due to a virus called hantavirus have spread panic at a time when the world is battling the pandemic of novel coronavirus, which began in China.

The novel coronavirus has killed over 16,000 people around the world and the outbreak is yet to be brought under control.

This morning, hantavirus became one of the top trends on Twitter after the Chinese state media tweeted about one person in the country dying due the virus. However, it turns out, hantavirus is not a new virus and has been infecting humans for decades.

Global Times, a state-run English-language newspaper, wrote on Twitter on Tuesday, "A person from Yunnan Province died while on his way back to Shandong Province for work on a chartered bus on Monday. He was tested positive for hantavirus. Other 32 people on bus were tested."

Global Times's hantavirus report on Twitter has been shared over 6,000 times.

On Tuesday, hantavirus was one of the top trends on Twitter.

WHAT IS HANTAVIRUS?

Some people are calling it a new virus but so is not the case. United States's National Center for Biotechnology Information (NCBI) in a journal writes that currently, the hantavirus genus includes more than 21 species.

"Hantaviruses in the Americas are known as 'New World' hantaviruses and may cause hantavirus pulmonary syndrome [HPS]," CDC says. "Other hantaviruses, known as 'Old World' hantaviruses, are found mostly in Europe and Asia and may cause hemorrhagic fever with renal syndrome [HFRS]."

Any man, woman, or child who is around mice or rats that carry harmful hantaviruses can get HPS.

People get HPS when they breath in hantaviruses. This can happen when rodent urine and droppings that contain a hantavirus are stirred up into the air. People can also become infected when they touch mouse or rat urine, droppings, or nesting materials that contain the virus and then touch their eyes, nose, or mouth. They can also get HPS from a mouse or rat bite.

In the US, 10 confirmed cases of hantavirus infection in people who visited Yosemite National Park in California, US, in November 2012, were reported. Similarly, in 2017, CDC assisted health officials in investigating an outbreak of Seoul virus infection that infected 17 people in seven states.

WHAT ARE THE SYMPTOMS OF HANTAVIRUS?

If people get HPS, they will feel sick one to five weeks after they were around mice or rats that carried a hantavirus.

At first people with HPS will have:

Fever
Severe muscle aches
Fatigue

After a few days, they will have a hard time breathing. Sometimes people will have headaches, dizziness, chills, nausea, vomiting, diarrhoea, and stomach pain.

Usually, people do not have a runny nose, sore throat, or a rash.

Houston, Mar 15: Researchers, studying the novel coronavirus, have found that the time between cases in a chain of transmission is less than a week, and over 10 per cent of patients are infected by someone who has the virus, but does not show symptoms yet, a finding that may help public health officials contain the pandemic.

The study, published in the journal Emerging Infectious Diseases, estimated what's called the serial interval of the coronavirus by measuring the time it takes for symptoms to appear in two people with the virus -- the person who infects another, and the infected second person.

According to the researchers, including those from the University of Texas at Austin, the average serial interval for the novel coronavirus in China was approximately four days.

They said the speed of an epidemic depends on two things -- how many people each case infects, and how long it takes cases to spread.

The first quantity, the scientists said, is called the reproduction number, and the second is the serial interval.

Due to the short serial interval of the disease caused by the coronavirus -- COVID-19 -- they said, emerging outbreaks will grow quickly, and could be difficult to stop.

“Ebola, with a serial interval of several weeks, is much easier to contain than influenza, with a serial interval of only a few days,” said Lauren Ancel Meyers, study co-author from UT Austin.

Meyers explained that public health responders to Ebola outbreaks have much more time to identify and isolate cases before they infect others.

“The data suggest that this coronavirus may spread like the flu. That means we need to move quickly and aggressively to curb the emerging threat,” Meyers added.

In the study, the scientists examined more than 450 infection case reports from 93 cities in China, and found the strongest evidence yet that people without symptoms must be transmitting the virus -- known as pre-symptomatic transmission.

More than one in ten infections were from people who had the virus but did not yet feel sick, the scientists said.

While researchers across the globe had some uncertainty until now about asymptomatic transmission with the coronavirus, the new evidence could provide guidance to public health officials on how to contain the spread of the disease.

“This provides evidence that extensive control measures including isolation, quarantine, school closures, travel restrictions and cancellation of mass gatherings may be warranted,” Meyers said.

The researchers cautioned that asymptomatic transmission makes containment more difficult.

With hundreds of new cases emerging around the world every day, the scientists said, the data may offer a different picture over time.

They said infection case reports are based on people's memories of where they went and whom they had contact with, and if health officials move quickly to isolate patients, that may also skew the data.

“Our findings are corroborated by instances of silent transmission and rising case counts in hundreds of cities worldwide. This tells us that COVID-19 outbreaks can be elusive and require extreme measures,” Meyers said.

Apr 12: India and other South Asian countries are likely to record their worst growth performance in four decades this year due to the coronavirus outbreak, the World Bank said on Sunday.

The South Asian region, comprising eight countries, is likely to show economic growth of 1.8 per cent to 2.8 per cent this year, the World Bank said in its South Asia Economic Focus report, well down from the 6.3 per cent it projected six months ago.

India's economy, the region's biggest, is expected to grow 1.5 per cent to 2.8 per cent in the fiscal year that started on April 1. The World Bank has estimated it will grow 4.8 per cent to 5 per cent in the fiscal year that ended on March 31.

"The green shoots of a rebound that were observable at the end of 2019 have been overtaken by the negative impacts of the global crisis," the World Bank report said.

Other than India, the World Bank forecast that Sri Lanka, Nepal, Bhutan and Bangladesh will also see sharp falls in economic growth.

Three other countries - Pakistan, Afghanistan and the Maldives - are expected to fall into recession, the World Bank said in the report, which was based on country-level data available as of April 7.

Measures taken to counter the coronavirus have disrupted supply chains across South Asia, which has recorded more than 13,000 cases so far - still lower than many parts of the world.

India's lockdown of 1.3 billion people has also left millions out of work, disrupted big and small businesses and forced an exodus of migrant workers from the cities to their homes in villages.

In the event of prolonged and broad national lockdowns, the report warned of a worst-case scenario in which the entire region would experience an economic contraction this year.

To minimize short-term economic pain, the Bank called for countries in the region to announce more fiscal and monetary steps to support unemployed migrant workers, as well as debt relief for businesses and individuals.

India has so far unveiled a $23 billion economic plan to offer direct cash transfers to millions of poor people hit by its lockdown. In neighbouring Pakistan, the government has announced a $6 billion plan to support the economy.

"The priority for all South Asian governments is to contain the virus spread and protect their people, especially the poorest who face considerable worse health and economic outcomes," said senior World Bank official Hartwig Schafer.
