New coronavirus infections in Iran have risen sharply since the country relaxed its restrictions on movement, while France has said it will reimpose strict lockdowns if cases surge when it begins to emerge from confinement next week.

Tehran on Wednesday reported 1,680 new infections, nearly double the figure four days ago and the highest daily figure since 11 April when it allowed a phased return to work amid fears of economic collapse. A ban on travel between cities and business at shopping malls has since also been lifted.

Latvia, Lithuania and Estonia will open their borders to each others’ citizens from 15 May, creating a Baltic “travel bubble” within the EU.

Hundreds of Indian police have tested positive for the coronavirus in recent days, raising alarm among an over-stretched force as it attempts to enforce the world’s largest lockdown.

At least 90,000 healthcare workers worldwide – and possibly twice that – are believed to have been infected with Covid-19, and more than 260 nurses have died, the International Council of Nurses (ICN) said.

Professor Salim Abdool Karim, the South African government’s chief adviser, said the country’s strict lockdown and proactive screening and testing programme had helped limit its death toll to 148.

We get an update from two doctors treating patients with the Navajo Nation, the largest Indigenous reservation in the country, which has been hard hit by the coronavirus pandemic. Dr. Michelle Tom is a member of the Navajo Nation and a family physician treating COVID-19 patients at the Winslow Indian Health Care Center and Little Colorado Medical Center in northern Arizona near the Navajo reservation. In Gallup, New Mexico, Dr. Sriram Shamasunder is leading a medical volunteer group of 21 nurses and doctors from the University of California, San Francisco as part of the HEAL Initiative. He says the coronavirus hit harder on the Navajo Nation due to a "trajectory of an underfunded health system," and notes the Indian Health Service is funded at one-third the rate per capita as Medicare. "The level of inequity that you're seeing … it's part of this pattern."

We go to Moscow for an update on the pandemic in Russia, where the coronavirus is spreading rapidly, with at least 10,000 new cases a day and the second-highest infection rate in the world, and more than 100 medical workers have died fighting the virus, and many have reported lack of personal protective equipment. Meanwhile, three Russian healthcare workers mysteriously fell from hospital windows over the past two weeks. Two died, and the one who is hospitalized had posted a video online to note the lack of medical equipment and said he had to keep working despite testing positive. We speak with Joshua Yaffa, Moscow correspondent for The New Yorker magazine.

A child was among sixteen migrants rescued four miles off the coast of France when their makeshift vessel bound for Britain ran into difficulties in the middle of the night, authorities said.

The group was picked up 3.8 miles off the French port of Calais after calling for help, French maritime authorities confirmed to AFP. A French maritime surveillance vessel rescued the migrants at around 5am and transported them to the Channel port of Dunkirk, where they were handed over to border police.

Vladimir Putin has told Russians they are invincible when they stand together, as he sought to send a message of unity after the country’s tally of Covid-19 cases reached the fifth highest in the world.

Addressing the nation in a speech as he presided over Victory Day celebrations, a sombre Putin invoked the memory of the country’s veterans who fought in the second world war.

We are united by our shared memory, hopes and aspirations, as well as a sense of shared responsibility for the present and the future. We know and strongly believe that when we stand together, we are invincible.”

The city's battle against the COVID-19 has finally started to show some positive results with the doubling rate of positive cases increasing from 8.3 days to 10 days. According to findings of the Central Committee, the doubling rate of cases was recorded between April 7 and April 17, which indicates that cases might now increase at lesser speed. While the doubling rate period at the national level is 9.5 days, the same in Maharashtra was 8.9 days.

Noting this, the Central Committee has lauded the Brihanmumbai Municipal Corporation's (BMC's) preventive measures, said a senior civic official.

Mortality rate decreases
In its findings, the Committee has analysed the number of infected patients and observed that the mortality rate among them in the BMC area was lower compared to that of the state. At the state level, an average of 4.3 patients are dying per 100 infected patients and in the BMC area, an average of 3.9 patients are dying every 100 infected patients. A civic official said that few days ago the average mortality rate of infected cases in the BMC area was 6.3 per cent, which too had reduced.

However, BMC now faces the challenge to cater to areas where earlier the rate of doubling of cases was low but has increased in the last couple of days. Wards like G South, G North and E, which have been reporting a high number of cases, are seeing an increase in the doubling rate period.

Earlier, on an average the cases used to double every 10.6 days in G south but now it has gone up to 17.6 days. But R central ward has seen a reverse trend. Its doubling rate period has gone down to 5.5 days from 16.9 days.

Contact tracing
The first COVID-19 positive case was detected on March 11, and since then the civic body has been tracing contacts of positive patients. Till April 26, as many as 1,29,477 were found through contact tracing, of which 21,053 were high-risk group contacts and 1,647 cases were positive.

The BMC, however, claimed that they were being able to control the number of cases due to the containment zones as people cannot move from one area to another and spread the infection. An analysis of the statistics of medical tests conducted across the country reveals that comparatively most number of the tests had taken place in the BMC jurisdiction. As many as 66,000 tests have been conducted in the city so far, an official said.

Containment efforts
Speaking on condition of anonymity, a senior civic official said, "The doubling rate period of 10 days is better than the national average of 9.5 and the mortality rate of 3.9 is better than the state as well as national figures. This has been done through containment efforts and aggressive contact tracing and quarantining."

He added, "Today, the battle against Coronavirus is being fought with the active cooperation of the municipal corporation, police, various government departments, private hospitals and many others. We once again appeal to the citizens of Greater Mumbai Municipal Corporation to follow the guidelines."

While many doctors have been complaining about the non-availability of safety equipment when they examine COVID-19 patients, a businessman has come to their aid by creating a cabin for such examinations, where they need not use PPEs.

The 38-year-old Vile Parle-based man has created an 'OPD' cabin that is divided into two sections for the doctor and patient. The doctor can examine the patient without using a mask or PPE as she/he does not come into direct contact with the patient, and can immediately sanitise the cabin after this. The businessman, Jatin Shah, gave one of the cabins free of cost to the Balasaheb Thackeray Trauma Care Centre at Jogeshwari last week, and every day doctors examine at least a 100 people in it.

Shah is involved with the aluminum industry and has used the material and glass to make the cabin. He has also donated 40 cabins to the Maharashtra, Goa and Karnataka governments to examine people at the states' borders.

Shah said, "I saw many videos on social media about the challenges doctors have been facing while treating COVID-19 patients. So I decided to invent something that would help them. Within two days I created this cabin and gave it to the Jogeshwari-based trauma care centre free of cost with the help of an NGO."

Jatin Shah, the businessman

Shah said, "At the borders, 4-6 hours after testing when the report comes, if a traveller is found to be COVID-19 positive, doctors send her/him to hospital and if any patient is found negative, she/he is allowed to enter the state. I took the help of Wipro general electric, which finalised the design of this cabin and asked the Seva trust in Mumbai to contact the hospital and get the cabin approved," Shah added.

Doctor speak

"The cabin is really useful. We sent our four labourers to Shah's factory to help him construct this cabin. We also issued a letter to him from hospital superintendent Vidhya Mane. Within two days he manufactured it and gave it to us," said Dr Rangnath Jawhar of Balasaheb Thackeray Trauma Care Centre.

Features of the cabin

The cabin is 8X4 ft and divided into two spaces separated by glass. One section is used by the doctor and the other by the patient. Screening equipment including a digital thermometer and a fever gun kept inside. Both sides have a mike and speaker. A 20 lt tank stores disinfectant which gets sprayed inside

A few days ago, Bollywood actor Irrfan Khan lost his mother and was unable to attend the funeral due to the lockdown that has been imposed. And now, in another unfortunate news, he has been admitted to the Kokilaben hospital in Mumbai due to colon infection. He's being currently treated for the same and his wife and children are with him.

Speaking about the same, the actor's official spokesperson said, "Yes it is true that Irrfan Khan is admitted to the ICU at Kokilaben in Mumbai because of a colon infection. We would keep everyone updated. He is under the doctor’s observation. His strength and courage have helped him battle and fight so far and we are sure with his tremendous willpower and prayers of all his well-wishers, he will recover soon."

In 2018, Khan was diagnosed with the Neuroendocrine Tumour and for the last two years, has been travelling back and forth for his treatment. Some of his films like Blackmail and Karwaan released in cinemas but he couldn't promote them due to his illness. He was last seen in Angrezi Medium and most of the Bollywood fraternity wished the actor for this moving and emotional film.

Khan is a fighter and will surely come out stronger and sooner, his fans and everyone from the fraternity are praying for his health and we cannot wait to see him back on the celluloid!

The Hong Kong airport is using several latest disinfection technologies including a full-body disinfection channel and cleaning robots to reduce the risk of the COVID-19 spread.

The disinfection channel is an enclosed facility similar to a telephone booth in size where users can complete disinfection and sanitizing procedures in 40 seconds, the city's Airport Authority (AA) said in a statement on Sunday.

The interior surface of the facility is equipped with antimicrobial coating which can remotely kill virus and bacteria on human bodies and clothing by using the technologies of photocatalyst and "nano needles" Xinhua news agency quoted the AA as saying, noting that the Hong Kong International Airport is the world's first to use the facility.

Currently, the disinfection channel is used by public health staff who bear quarantine duties at the airport.

Autonomous cleaning robots have also been used to ensure thorough disinfection of public areas and passenger facilities at the airport.

The cylindrical robots, equipped with ultra violet light sterilizer and air sterilizer, operate round-the-clock in public toilets and key operating areas in the terminal building, the AA said.

The robots can move around autonomously and sterilize up to 99.99 per cent of bacteria in its vicinity, including both the air and object surfaces, in just 10 minutes.

Besides, the AA is also conducting a pilot test of applying antimicrobial coating at all passenger facilities, including check-in counters, baggage trolleys and elevator buttons, among others.

After completion of the trial in May, the AA will consider implementing it as a long term disinfection measure. Hong Kong has reported 1,037 coronavirus cases with four deaths.

South Korean infectious disease experts have downplayed concerns that patients could get reinfected with COVID-19 after recovering. While hundreds in South Korea have tested positive again after their release from hospitals, Oh Myoung-don, who heads the central clinical panel on new infectious diseases, on Wednesday said there was a "high possibility" that such test results were flawed.

He said South Korea's standard real-time PCR tests, designed to amplify the genetic materials of the virus so that even tiny quantities are detected, doesn't reliably distinguish between remains of dead virus and infectious particles. He said lab tests on animals suggest that COVID-19 patients would maintain immunity for at least a year after their infections. He also said it was unlikely that the virus could be reactivated after remaining dormant when it doesn't seem to be a type that causes chronic illnesses.
