Covid-19 in staff working in a Nursing Home in Sweden.
Covid-19 is a viral disease that is common to the majority but can be serious for some, especially the elderly and fragile individuals. A (unnamed) elderly Nursing Home for Old People in the Gothenburg region found some cases of covid-19 among the residents. To investigate whether the infection was among the staff, all employees who came to work on April 6, 2020 were offered to undergo a simple covid-19 examination and sampling. Sixty-five people were surveyed and 57 stated that they would work while 5 came in extra for the sampling but would not work that day and 3 did not answer the question. Of the 57 who stated that they planned to work that day, 23 (40%) had some of the symptoms of sniffing, sore throat, cough or fever. Four of these 57 were PCR positive for covid-19. ( 7% ) Two of these had some symptoms while two of the PCR positive ones were symptom free. Only one of the 57 had IgG antibodies and one had IgM antibodies to covid-19, both of which were symptom-free.This simple survey is fraught with a number of weaknesses. It is not clear whether residents have infected the staff or vice versa. The samples for PCR were taken adequately and analyzed using accepted methodology while the antibody tests were patient-close fast tests whose performance may not be optimal. It is just a retirement home and a similar survey would need to be done on more senior housing to be able to draw some safe conclusions.The proportion of personnel who were PCR positive was relatively low, but it is worrying that quite a few with, in themselves mild, symptoms planned to work at the elderly home even though they had symptoms. This can have negative consequences in a future situation where a larger proportion of the staff is PCR positive for covid-19. There are probably many reasons why, despite symptoms, they still go to their workplace. These causes would be very urgent to investigate further. It is possible that the staff of the elderly homes would need support in the form of someone who was present when they arrived and could discuss with them if they have symptoms that may involve an infection risk.

Ενδιαφέρουσα άποψη. Αν το IgM/IgG test τους είναι αξιόπιστο και ειδικό για τον covid2019 τότε όποιος έχει IgG και είναι μόνος του, είναι και αυτός που έφερε την επιδημία.... Αν κάποιοι έχουν IGΜ αλλά δεν έχουν συμπτώματα, προφανώς μόλις πέρασαν την νόσο, μπορεί να έχουν και pCR αρνητική. Δεν μας λέει πως πήραν την PCR, το φαρυγγικό δείγμα για PCR έχει 32% ευαισθησία. Η συμπεριφορά του ιού αλλά και η συμπεριφορά των Σουηδών (πάνε να δουλέψουν με πυρετό), εργαζόμενων αλλά και των συγκεκριμένων ερευνητών (αλήθεια έχει κάποια στοιχειώδη ιχνηλάτιση η μελέτη;), δείχνει ότι μάλλον τα πράγματα δεν είναι δύσκολα λόγω μικρής θνητότητας του ιού. Είναι δυστυχώς η απόδειξη ότι ένας ιός που μεταδίδεται χωρίς συμπτώματα, αν είναι θανατηφόρος, απλά μπορεί να εξαφανίσει μια χώρα όπως η Σουηδία.

MADRID (AP) — As the coronavirus pandemic throws millions out of work and devastates economies worldwide, governments are struggling with the delicate balance between keeping people safe from a highly contagious virus and making sure they can still make a living or even have enough to eat.
Workers in some nonessential industries were returning to their jobs Monday in Spain, one of the hardest-hit countries in the coronavirus pandemic, while in South Korea, officials were warning that hard-earned progress fighting the virus could be eroded by new infections as restrictions ease.
The decisions are complicated because each nation is on its own coronavirus arc, with places like Britain, Japan and parts of the United States still seeing increasing daily levels of deaths or infections; France and New York hoping they are stabilizing, albeit at a high plateau of deaths; and hard-hit nations like Italy and Spain seeing declines in the rates of increase.
Spanish Prime Minister Pedro Sánchez said his government must balance its response to the virus crisis that “threatens to destroy lives and at the same time destroy the economic and social fabric of our country.”
Seeking to restart manufacturing, Spain’s government is allowing workers to return to some factory and construction jobs. Retail stores and services remain closed and office workers are strongly encouraged to keep working from home. A prohibition on people leaving home for anything other than groceries and medicine will remain for at least two weeks under the state of emergency.
‘’(Spain’s) economy is more vulnerable to the crisis since it relies on services like tourism that are severely harmed by the pandemic. That means it will likely have a deeper recession,” European Central Bank Vice President Luis de Guindos told Spain’s La Vanguardia newspaper.
Yet some health experts and politicians argue it's premature to ease the lockdown in a nation that has suffered 17,489 deaths and reported 169,496 infections, second only to the United States' 557,000 infections. But Spain on Monday reported its lowest daily growth in infections in three weeks.
Italy recorded its lowest daily virus death toll in three weeks at 431, putting its total deaths at over 19,800. In Madrid, José Pardinas took a mask being handed out by police as he walked to work at a moving company that was re-starting operations after a three-week halt.
“The company hasn’t given us any protective equipment. I’m quite nervous about contracting the virus because my family can’t afford more time without an income,” Pardinas said. Pakistan’s Prime Minister Imran Khan, meanwhile, issued a global plea to the world’s richer countries and international financial institutions to provide debt-relief for poor countries, where forced lockdowns are crippling already troubled economies and causing widespread hunger for the poor.
His government has launched an ambitious $8 billion program to help the millions near the poverty level. Khan last week relaxed his country's lockdown to allow the construction industry, which employs the vast majority of Pakistan's daily wage earners, to re-open.
German Chancellor Angela Merkel, who has urged a cautious approach to any loosening of restrictions, will hold a video conference with regional governors Wednesday, after the governor of the state with the most infections called for a “road map” to return to normality.
Armin Laschet, governor of North Rhine-Westphalia, said “the willingness for restrictions also needs the prospect of normalization.” His government came up with a plan for gradually easing the restrictions imposed on March 22, when public gatherings were limited to only two people.
In South Korea, Prime Minster Chung Sye-kyun said officials were discussing new public guidelines that would allow for “certain levels of economic and social activity” while also maintaining distance to slow the virus' spread.
South Korea’s caseload has slowed from early March, when it was reporting around 500 new daily cases, but officials have warned of a broader “quiet spread'' at locations such as bars, which are still open. President Moon Jae-in vowed Monday to focus on saving jobs and protecting the economy amid a sharp increase in the number of people seeking unemployment benefits.
South Korea’s vice health minister, Kim Gang-lip, said a quick return to normality was “virtually impossible” considering the threat of new infections. “A premature easing (of social distancing) would come at an irrevocable cost, so we should approach the issue very carefully, and invest deep thought into when and how to transition,” Kim said.
In Sri Lanka, the government announced plans to reopen schools and universities in May. The pandemic's new epicenter is now the United States, which has seen more than 22,000 deaths, the world’s highest. About half have been in the New York metropolitan area, but hospitalizations are slowing in the state and other indicators suggest lockdowns and social distancing are working.
U.S. infectious disease expert Dr. Anthony Fauci said parts of the country could gradually reopen as early as next month. In Britain, the death toll passed 10,600. Prime Minister Boris Johnson, the first major world leader to test positive for the virus, paid an emotional tribute to the country’s National Health Service after leaving the hospital on Sunday. Johnson, who spent three nights in intensive care, especially thanked two nurses who stood by his bedside for 48 hours “when things could have gone either way.”
Japan, the world’s third-biggest economy, has seen new infections climb rapidly and now has 7,255 confirmed cases. Japanese companies have been slow to switch to working remotely and many people are still commuting, even after a state of emergency was declared for seven prefectures, including Tokyo.
To encourage people to stay home, the Japanese government released a video showing Prime Minister Shinzo Abe cuddling his dog, reading a book and clicking a remote control at home but the message drew scathing criticism on social media.
Infections also spiked in Indonesia, the world's fourth-most populous country, where President Joko Widodo pledged to be more transparent about the coronavirus. Last month, Widodo admitted he deliberately held back information about the virus' spread to prevent panic. On Monday, he asked his ministers and the COVID-19 task force to be transparent with the public.
Indonesia has 4,557 confirmed infections and 399 deaths, Asia's highest recorded number of fatalities after China. More than 1.8 million coronavirus infections have been reported and over 114,000 people have died worldwide, according to Johns Hopkins University. The figures understate the true size and toll of the pandemic, due to limited testing, uneven counting of the dead and deliberate under-counting by some governments.

Οι Ισραηλινοί Βατραχάνθρωποι (Μονάδα Shayetet 13) αναπτύσσουν "έξυπνες" λύσεις αναπνευστήρων για να υποστηρίξουν το υγειονομικό σύστημα στην αντιμετώπιση της Πανδημίας στην χώρα τους, βάσει της εμπειρίας τους.

The elite unit, which trains experienced divers and as a result has a great deal of experience in under-water breathing technologies and oxygen tanks, developed a unique method.

The Shayetet 13 naval commando unit is helping in the IDF’s fight against the coronavirus by developing advanced solutions to compress oxygen.
The famed elite unit, which trains divers and as a result has a great deal of experience in underwater breathing technologies and oxygen tanks, developed a unique method and is playing a key role in the fight against the deadly disease.
The unit's research and development teams, in collaboration with the Health Ministry, Yad Sarah and other organizations, have converted an operational production line into a production line for medical oxygen compression systems.
“Apart from the system’s development and supply, the unit will provide a logistical response and will assist in transporting oxygen tanks as needed,” the IDF said.
Amid fears that the number of patients needing respiratory assistance may exceed the number of respirators available, the Defense Ministry has been working to produce Israeli-developed ventilators with defense companies and start-ups in the country.
Two weeks ago The Jerusalem Post learned that soldiers in the elite General Staff Reconnaissance Unit had been going across the country counting the number of respirators in each hospital or healthcare facility.
On Friday, the Defense Ministry addressed the acute shortage in ventilators in the country and announced that the Directorate for Defense R&D (DDRD) and Elbit Systems set up a serial production line to manufacture thousands of LifeCan One ventilators.
The smart automatic ventilators, which cost around $2,000 per unit, are based on a unique technology developed by LifeCan Medical and will enable medical centers to provide initial stage respiration care to a larger number of patients who suffer from less severe respiratory conditions.
“The national goal is to reach a fully independent production capability supplying thousands of ventilators to Israel's health system,” said Brig.-Gen. (ret.) Dr. Daniel Gold, head of DDRD. “The decision to leverage the impressive capabilities of our defense industry, which is capable of quality production, in record time, of anything, whether it is unmanned aerial systems or ventilators, is paying off and will enable us to reach the goal set.”
The production of the ventilators will be done in two separate facilities in order to provide 3,000 units in a short period of time and ensure production continuity.
Micha Oestereich, CEO of LifeCan told the Post that the company will start to manufacture the ventilators at the Elbit production facilities at the end of Passover and aims to produce 500 units per week.
“We do not manufacture ICU ventilators, but emergency ventilators which support the extensive ones, which are in the ICU, which can cost $150,000. We are not going to replace these ventilators, but we will support them,” Oestereich said.
The automatic ventilators can be operated by paramedics and general practitioners and operated in non-hospital environments.

“When you plan to have thousands of patients unconscious in the hospital and there isn't room in the ICUs, their beds will be in the parking lots. And in these cases our ventilators will be used,” Oestereich said.
“There will not be any case like in Italy where doctors have to give up on a patient because there aren't enough ventilators. I hope that no patient in 2020, in Israel and hopefully all over the world, will be given up on by medical staff.”
The LifeCan ventilators, which will be supplied by Elbit, will be made on one of the company’s production lines, which usually produces bombs and missiles.
Two weeks ago the Defense Ministry said a radar system used by the IDF to secure the country’s borders has been adapted to monitor the vital signs of coronavirus patients.
Two military radar systems, developed by Elbit and Israel Aerospace Industries, have been adapted by the National Emergency Team of DDRD in the Defense Ministry to remotely monitor and measure the vital signs of coronavirus patients using a combination of radar and electro-optical sensors.
