    Administration of Donald J. Trump, 2020 Remarks at a White House Coronavirus Task Force Press Briefing March 31, 2020 The President. Thank you very much, everyone. Our country is in the midst of a great national trial, unlike any we have ever faced before. You all see it. You see it probably better than most. We're at war with a deadly virus. Success in this fight will require the full, absolute measure of our collective strength, love, and devotion. Very important. Each of us has the power, through our own choices and actions, to save American lives and rescue the most vulnerable among us. That's why we really have to do what we all know is right. Every citizen is being called upon to make sacrifices. Every business is being asked to fulfill its patriotic duty. Every community is making fundamental changes to how we live, work, and interact each and every day. And I wouldn't be surprised to see this going on long into the future, when this virus is gone and defeated. Some of the things we're doing now will be very good practice for the future, including for not getting the flu, which is very devastating also. So some of what we're learning now will live on into the future—I really believe that: shaking hands or not shaking hands, washing hands all the time, staying a little apart. Fifteen days ago, we published our nationwide guidelines to slow the spread of the virus. On Sunday, I announced that this campaign will be extended until April 30.

  • Patient Referral Guidelines
    SULTANATE OF OMAN MINISTRY OF HEALTH MANUAL ON PATIENT REFERRAL GUIDELINES SECOND EDITION – 2004 DIRECTORATE GENERAL OF HEALTH AFFAIRS 1 PREFACE Patient Referral system is the back-bone of health services infrastructure, offering highest possible levels of health services to each and every member of the community through a network of Primary, Secondary, & Tertiary Health Care providing institutions. MOH assigns high priority to this essential component of health services, evidenced by a recent National Workshop and revision of the Manual on Patient Referral Guidelines within five years of publication of the previous edition of the manual. Manual on Patient Referral Guidelines has been revised in consideration with the changing needs of the community, rapid development of health services in Oman, and changing concepts in the medical profession. We have also attempted to make the referral system even more patient friendly, as well as making the manual user-friendlier. Following changes in the manual (and policies therein) make it simpler to read and understand, despite further elaboration of referral protocols and inclusion of beneficial and relevant information. 1. Permissibility of skipping service levels with certain explicit criteria applied. Thereby, offering referring clinicians a margin to select appropriate referral institution and save precious time of patients, making the referral system more patient friendly. 2. Necessary amendments in the Patient Referral Form, making it suitable to serve the purpose as an appointment request form and monitoring the referral system as well. 3. Revision of concepts and definitions for referral assessment criteria, and their incorporation in Monitoring & Reporting system. 4. Inclusion of scientific definitions for clinical categories of referrals i.e.

  • April 7, 2020 Summary the United States Now Has 383,965
    April 7, 2020 Summary The United States now has 383,965 confirmed COVID-19 cases and 12,021 reported related deaths. France’s health minister announced that the country had not reached the peak of its epidemic and was “still in a worsening phase.” France has recorded more than 78,167 cases and 10,328 deaths. British Prime Minister Boris Johnson is receiving oxygen support in an intensive care unit as he battles a worsening coronavirus infection. Turkey has ordered all citizens to wear masks when shopping or visiting crowded public places and announced it will begin delivering masks to every family, free of charge. South Carolina issued a shelter-in-place order, effective Tuesday at 5 PM. It is the 42nd state to issue an order of this kind. Approximately 95 percent of the U.S. population is or will soon be under directives to stay home. New Jersey Governor Murphy signed an executive order closing all state parks, state forests, and county parks in the state, because too many people have failed to observe social distancing guidelines. In New York, the death toll reached a new one-day high, as 731 more people died in the state. The grim tally followed two days in which new deaths dropped below 600. Governor Cuomo said that while the state’s new death toll was upsetting, he was encouraged by data showing that the rate of hospitalizations had fallen for several days, suggesting that the spread of the virus could be plateauing. President Trump granted Governor Cuomo’s request to allow the treatment of COVID-19 patients on the USNS Comfort.

    xxxxxxxxxx Canadian Military Hospitals at Sea 1914-1919 Jonathan C Johnson, OTB S there was an ocean between Canada and the fighting during WWI, the movement of casualties needing lengthy treatment required special arrangements. Many of the Acasualties returning home, especially in 1915 and 1916, came back to Canada on relatively empty troop ships (ex-passenger ships) and were accompanied by a small medical team. The more serious casualties came home on either hospital ships or ambulance transports, most of which were equipped as floating convalescent hospitals. Hospital ships and ambulance transports generally were identically equipped. The former were commissioned naval auxiliaries painted white with green stripe and large red crosses and protected by the Geneva Convention (Figure 1). The latter were normal naval auxiliaries painted troop ship colours that sailed in convoy and were not protected by the Geneva Figure 1. Colour postcard of HMHS LETITIA with the correct Convention. Like most military colour scheme for a commissioned hospital ship under the Geneva Convention. units each ship had an ‘Orderly Room’ where mail could be posted and, if lucky, picked up upon arrival at port. Military service personnel overseas could post mail unpaid. For much of the war, the Canada Post Office added postage upon arrival in Canada so postage due would not be applied. Canada had six hospital ships and ambulance transports during WWI. Of this number, two were lost while in service. A return trip from Liverpool to Canada and back took one month.
