Novel coronavirus survives 28 days on banknotes, glass, stainless steel: Australian researchers

Melbourne, Oct 12: The virus that causes Covid-19 can survive on banknotes, glass and stainless steel for up to 28 days, much longer than the flu virus, Australian researchers said on Monday, highlighting the need for cleaning and handwashing to combat the virus.

Researchers at Australia's national science agency, CSIRO, found that at 20 degrees Celsius (68 degrees Fahrenheit) the SARS-COV-2 virus remained infectious for 28 days on smooth surfaces such as plastic banknotes and glass found on mobile phone screens. The study was published in Virology Journal.

By comparison, Influenza A virus has been found to survive on surfaces for 17 days.

CSIRO's research involved drying virus in an artificial mucus on a range of surfaces at concentrations similar to samples from Covid-19 patients and then extracting the virus after a month.

Experiments done in controlled laboratory environments at 20, 30 and 40 degrees C showed that the survival time declined as the temperature increased.

"Establishing how long the virus really remains viable on surfaces enables us to more accurately predict and mitigate its spread and do a better job of protecting our people," CSIRO Chief Executive Larry Marshall said in a statement.

Proteins and fats in body fluids can also sharply increase virus survival times.

"The research may also help to explain the apparent persistence and spread of SARS-CoV-2 in cool environments with high lipid or protein contamination, such as meat processing facilities, and how we might better address that risk," said Trevor Drew, director of the CSIRO’s Australian Centre for Disease Preparedness.

Australia has fared much better than most other rich nations in combating Covid-19, with a total of about 27,000 infections and 898 deaths in a population of 25 million.

The epicentre of the country's second wave of infection, Victoria state, reported 15 new cases on Monday, well shy of a target of less than five which the government has set for the easing of a hard lockdown in the state capital Melbourne.

New South Wales, the most populous state, reported six new cases on Monday, five of whom were returned travelers in quarantine.

The Israeli military says it has taken full control of the Rafah crossing, which borders Egypt.

Israeli tanks took over the crossing after advancing during the night following heavy bombardment of residential areas.

The military said the crossing is now disconnected from the Salah a-Din road in eastern Rafah, which was seized before.

Tel Aviv said it would continue the operation in Rafah even after the Palestinian resistance movement Hamas said it had agreed to a proposal on ceasefire in Gaza put forward by Qatari and Egyptian mediators.

Earlier, Israeli military aircraft heavily bombed Rafah accompanied with ground advances shortly after Hamas said it had accepted the ceasefire proposal.

The official Palestinian news agency Wafa and Egyptian media said Israeli military vehicles advanced towards the Palestinian side of the Rafah crossing with Egypt, as well as the Karem Shalom crossing with the Israeli-occupied territories.

A Palestinian security official and an Egyptian authority have told the Associated Press news agency that Israeli tanks have entered Rafah, reaching as close as 200 meters from Rafah’s border crossing with neighboring Egypt.

The Israeli military has said it was conducting “targeted strikes” against Hamas in eastern Rafah.

Israeli prime minister Benjamin Netanyahu's office has also said "Israel is continuing the operation in Rafah to exert military pressure on Hamas" in order to advance the release of captives and what it called "the other objectives of the war."

In the meantime, it described the proposal on ceasefire as "far from Israel's essential demands," but added that it would send negotiators for talks "to exhaust the potential for arriving at an agreement."

The military strikes on Rafah came ahead of talks in Egypt on Tuesday aimed at sealing a truce proposal accepted by Hamas, which was put forward by Qatari and Egyptian mediators. 

According to a copy of the proposal, there will be three phases to ending Israel’s onslaught against Gaza.

The first phase calls for a complete withdrawal of Israeli troops from the Netzarim corridor and the return of displaced Palestinians to their homes. The second phase involves an announcement of a permanent cessation of military operations. In the last phase, there would be a complete end to the blockade of the Gaza Strip. 

In return, Israel would be required to release an unspecified number of Palestinian prisoners, withdraw its troops from certain regions of the Gaza Strip, and allow Palestinians to travel from the south of the coastal sliver to the north.

About 1.5 million Palestinians are sheltering in Rafah, once designated a “safe zone” by the Israeli military. Palestinians are now struggling to evacuate the city, after the Israeli military dropped leaflets ordering them to leave as a large-scale assault on the city is planned.

UN Secretary General Antonio Guterres has said that a ground invasion of Rafah would be “intolerable” and called on Israel and Hamas “to go an extra mile” to reach a truce deal.

“This is an opportunity that cannot be missed, and a ground invasion in Rafah would be intolerable because of its devastating humanitarian consequences, and because of its destabilizing impact in the region,” Guterres told reporters on Monday ahead of a meeting with Italian President Sergio Mattarella in New York.

Jordanian Foreign Minister Ayman Safadi has also warned that Israel is “jeopardizing the deal by bombing Rafah.”

As her health deteriorated, she was admitted to the KMC Hospital in Mangaluru, where she failed to respond to the treatment and died on Friday night.

It is learned that the KFD is slowly spreading to the newer areas of coastal and malnad areas of Karnataka

According to officials, KFD spreads due to bites of ticks that generally survive on monkeys. This tick bites humans which causes the infection. Humans also contract the disease by coming in contact with cattle bitten by ticks.

Maharashtra Leader of Opposition Vijay Namdevrao Wadettiwar waded into controversy after he alleged that an RSS-affiliated cop, and not terrorist Ajmal Kasab, killed former state anti-terrorism squad (ATS) chief Hemant Karkare during the 26/11 Mumbai terror attack.

In a video statement released on Saturday, the Congress leader alleged that the bullet that killed IPS officer Hemant Karkare did not come from the gun of Ajmal Kasab or any of the other nine Pakistani terrorists involved in the attacks.

Instead, he claimed it came from the weapon of a police officer allegedly "dedicated to" the Rashtriya Swayamsevak Sangh (RSS).

Wadettiwar also accused Ujjwal Nikam, the special public prosecutor in the case and a BJP Lok Sabha candidate from Mumbai North Central, of suppressing this information, labeling him a "traitor."

He questioned the BJP's decision to nominate Nikam for the Lok Sabha polls, accusing the party of protecting traitors.

“During the probe, key information was out. However, it was suppressed by Ujjwal Nikam, who is a traitor. My question is, why is BJP protecting a traitor and nominating such a person for Lok Sabha polls? By doing this, BJP is protecting traitors," Wadettiwar alleged, Times of India reported.

These allegations drew strong responses from Nikam and Deputy Chief Minister Devendra Fadnavis.

Nikam condemned Wadettiwar's statement as "baseless and irresponsible," expressing pain at the doubts raised over his integrity.

He emphasized the legal steps taken to convict Kasab, calling Wadettiwar's remarks an insult to the victims of the 26/11 attacks.

“What a reckless statement is being made. I am pained by such baseless allegations, raising doubts over my integrity. It clearly reflects the level of electoral politics. I never thought politicians will stoop to such low levels. For political gain? He (Wadettiwar) is insulting not me, but the 166 departed souls and all persons injured in the 26/11 attacks," Nikam said.

He added, “They (Congress) hold Kasab as innocent. Even Pakistan had accepted that Kasab was involved in the conspiracy and in the terror attack on India and was guilty".

He said Indians very well know the legal steps he had taken to ensure Kasab’s conviction.

Nikam said citizens of the nation would on 4 June, the day of results for Lok Sabha polls, give their reply to such allegations, adding he wished not to dignify the “desperate disinformation” with a further response.

Meanwhile, BJP leader and Deputy CM Fadnavis said, “Our alliance is with Nikam, while Congress has joined hands with Kasab".

Shiv Sena spokesperson Kiran Pawaskar said NIA should arrest Wadettiwar and ask him why he was defending Kasab.

Pawaskar criticized the Congress for allegedly supporting terrorists and expressed surprise at the silence of Shiv Sena chief Uddhav Thackeray on the matter.

“From Wadettiwar’s statement, it appears Congress is supporting terrorists who attacked Mumbai. More shocking is the fact that Sena (UBT) chief Uddhav Thackeray has maintained silence over the episode,” he said.
