WHO recommends corticosteroids for severe COVID-19 cases, China proves coronavirus transmits by air
Coronavirus vaccines, which are being developed in different countries, must be at least 50 percent effective. Consequently, registration of the less effective vaccines is not desirable, reported the World Health Organization. According to the official data, 31 vaccines in the world have passed various stages of clinical trials, including human trials. 142 companies are close to the finish.
“Each country has a sovereign right to define its policy for vaccination or any other therapeutic intervention in its population, but it must be guided by the highest possible ethical standards, the highest possible scientific standards,” said Dr. Mike Ryan, Executive Director of the WHO’s Health Emergencies Program.
The world organization also stressed the need for states to focus on switching to normal life after quarantine. The WHO officials said governments need to prevent the virus from spreading in public places such as stadiums, churches and other places with large crowds. It was offered to keep testing to stop the spread of the epidemic as well as to comply with restrictive measures.
After a number of researches, the WHO recommended using corticosteroids in patients with COVID-19.
“We recommend systemic corticosteroids for the treatment of patients with severe and critical COVID-19,” noted the recommendations.
The organization suggested not to use corticosteroids in the treatment of patients with non-severe COVID-19.
Meanwhile, COVID-19 can be transmitted by air from an infected person without symptoms in poorly ventilated places. The new scientific research, which was conducted on one of the buses in China, proved the statement of epidemiologists.
A person infected with coronavirus without any symptoms and without a protective mask transmitted the disease to a third of the passengers on the poorly ventilated bus during a trip lasting less than an hour. Scientists proved that the radius of the infection turned out to be much larger than previously thought.
Epidemiologists previously claimed that coronavirus is transmitted by droplets when infected people sneeze or cough. The theory of airborne transmission of the virus has been rejected by the health authorities of many countries. However, the situation changed in the summer, due to the pressure from many experts on respiratory viruses and the accumulation of new knowledge from research.
Italy proposed European Union mutual coronavirus testing for tourists.
“We are finalizing a cooperation agreement with the Italian Minister of health, Roberto Speranza, to ensure reciprocity with all European countries, starting with France and Germany. Those who leave and those who come will have to pass the test. It’s a way to get back to travelling, but safe,” said Italian Deputy Health Minister Sandra Zampa.
Italy opened its borders on June 3, allowing EU citizens to travel to the country. The total number of infected people here has reached 271,515 since the beginning of coronavirus spread. Approximately 35,500 patients died.
According to Johns Hopkins University, more than 26,050,603 people in 188 countries caught the infection. Over 863,488 people died. Nearly 17,306,848 recovered. The United States still has the biggest number of over 6,114,834 cases and deaths, followed by Brazil with 3,997,865 cases, India with 3,853,406 cases and then Russia, Peru, Colombia, South Africa, Mexico, Spain, Argentina and Chile.
