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.

Bengaluru, Apr 11: Congress leader Rahul Gandhi and the party's unit in Karnataka have highlighted the statement of Class 12 Board exam topper from the state, Vedant Navi, and claimed that "it was a matter of pride as their schemes were bringing effective social and economic changes".

The Congress on Thursday launched a social media campaign by releasing posters and short videos.

Rahul Gandhi in his social media post said, “Such 'Success Stories' make me believe and ensure that our 'Mahalakshmi' guarantee of putting Rs 1 lac every year in women's accounts will prove to be a revolutionary step to shaping the country's fate.”

“Congress's Gruha Lakshmi scheme going on in Karnataka under which more than 1 crore women get Rs 2,000 every month, using the same money a mother taught her son Vedant and he got second rank in the whole state in PUC exam,” Rahul Gandhi stated.

“Vedant's story is a living example of Indian women's penance and willpower to strengthen the house with pai-pai. Imagine, when women of poor families across the country will get Rs 1 lakh every year through the 'Mahalakshmi Yojana', how many Vedantas will change the future of the family with their talent? This historic plan of Congress will give the dreams of poor families a flight into reality,” Rahul Gandhi said.

The Congress in Karnataka said the schemes of the government were giving succour to the people. “It is a matter of pride that in a span of 10 months, our government’s schemes are bringing effective social and economic changes,” the party claimed.

“It is a testimony to the success of the Gruha Lakshmi scheme that the family of Vedant, who secured first rank in the Arts stream, was supported by the money provided by the Gruha Lakshmi scheme. Our schemes have brought changes in many people’s lives. The Congress party has built the lives of the people and thereby built the nation,” the Congress stated.

Vedant Navi had secured first rank in Arts Stream in Karnataka. He is the overall second-topper.

“My father is no more. My mother faced difficulties as the family was debt-ridden. In this crunch time, the money received through the Gruha Lakshmi scheme (Rs 2,000 every month given for women heads of family) helped my studies and hostel stay and other expenditures,” Vedant had stated.

Bengaluru: Karnataka State Natural Disaster Monitoring Centre (KSNDMC) has issued a series of animated shorts in Kannada advising people of appropriate measures to take during extreme temperatures to keep oneself safe.

 “Karnataka has not seen such extreme temperatures and heat waves in the recent past. So, we wanted to ensure a wider reach for safety measures, therefore we decided to issue them in a reader-friendly format,” said an official from KSNDMC.

Meteorological Centre Bengaluru, Indian Meteorological Department, had issued a five-day heat wave warning, lasting till April orange alert, for parts of Karnataka.

“In places like Bagalkote, Vijayapura, Kalaburgi, Yadgir, Raichur, Koppal, Ballari, Tumkur, Mandya, Gadag, Davangere and Chitradurga, the temperature is likely to touch 40 degrees Celsius tomorrow,” said C P Patil, director of the centre.

On April 25, these places recorded a maximum temperature of 39 degrees Celsius.

Orange alert would mean increased likelihood of heat illness symptoms in people who are exposed to sun for a prolonged period of time as well as those who do heavy manual work.

According to Patil, coastal Karnataka will also have very hot and humid weather conditions, making it very uncomfortable for people there.

“It’s best for children and old people to avoid exposure to heat in coastal areas too,” added Patil.

In places where heat wave is predicted, people are advised to avoid direct exposure to sunlight between 12 noon and 3pm.

“When they go out, it is best to use protective goggles, an umbrella or a hat. Also aerated drinks must be avoided since they cause dehydration. Best to drink water as much as possible, even if you don’t feel thirsty,” said M Rajavel, head of LACD, Meteorological Centre, Bengaluru.

People are also advised not to leave the children or pets inside parked vehicles.

The maximum and minimum temperatures of Bengaluru are very likely to be around 37 degree Celsius and 23 degree Celsius respectively for the next 48 hours, said Patil.

Hassan recorded the highest jump from its normal minimum temperature. It recorded 22.6 degrees Celsius, about 2.8 degrees more than usual.

According to IMD, on April 29 light rain is also very likely in isolated places over Bidar, Kalaburgi, Yadgir, Vijayapura, Chikkamagaluru, Hassan, Kodagu, Mysuru, Mandya and Chitradurga districts.

On April 30, light rain is predicted again for Bidar, Kalaburgi, Yadgir, Vijayapura, Raichur, Koppal, Ballari, Chikkamagaluru, Tumkur, Chikkaballapura, Bengaluru Rural, Bengaluru Urban and Kodagu districts.

Incidentally, KSNDMC has also issued a series of animated advisory for lightning safety.

“We also update temperature every 15 minutes in our X handle in coordination with IMD,” added the KSNDMC official.

The Iranian Army Chief Commander Major General Abdolrahim Mousavi says the country will not hesitate to give a “stormy and unified” response to any act of aggression against it.

In a Monday message marking the National Army Day, Mousavi said great defensive measures of the country’s Army and Armed Forces have resulted in strong deterrent power.

Iran has conveyed its message of power to the world in a way that the world has realized that the Iranian Armed Forces will give a “stormy and unified” response to any aggression against the country’s national interests, borders and security, he added.

The top commander noted that Iran’s firm response to an act of aggression by the usurping Israeli enemy against its diplomatic premises in the Syrian capital of Damascus brought joy to oppressed nations, especially the resilient people of Palestine and Gaza.

Mousavi emphasized that the retaliatory strikes, dubbed Operation True Promise, revealed only a part of the capacity and strong will of the Iranian Armed Forces and were carried out in cooperation among the Islamic Revolution Guards Corps (IRGC) Aerospace Division, the Army, and the Defense Ministry.

He said the Army has played a key role in strengthening the country’s defense power, independence and lasting security by implementing various measures.

It has constructed strategic drone and underground tactical bases and made hundreds of modern defense achievements in the land, air, sea and space sectors in addition to advancing in the fields of science and technology, he explained.

Now the enemies lack the courage to carry out any act of aggression against the Islamic establishment and the noble Iranian nation, the top commander said.

He added that Iran has staged several joint military drills to enhance national security and dignity.

The Israeli airstrikes on Iran’s embassy compound in Damascus killed two generals of Iran’s Islamic Revolution Guards Corps (IRGC), Brigadier General Mohammad Reza Zahedi and General Mohammad Hadi Haji Rahimi, as well as five of their accompanying officers.

In response, on Saturday night, the IRGC targeted the Israeli-occupied territories with a barrage of drones and missiles. The extent of the damage on Israeli military bases across the occupied territories is yet to be specified.

Following the reprisal, Iran warned Israel against taking any retaliatory actions and also urged the US to try not to involve itself in the conflict and signaled that it viewed the matter as “concluded.”
