Who is infected with the corona virus without showing symptoms, is considered to be a Patient with a “silent infection”. People who are not in direct contact with a proven Corona case, be tested without symptoms only rarely, so you’ll learn nothing from it.
Still be Infected thus become the unwitting Vectors and are considered to be high risk in the spread of Sars-CoV-2. Also children who suffer from rare, severe cases of Covid-19, belong to this carrier group.
Difficult to identify unreported cases of infection with Sars-CoV-2
to tie, how many people are actually infected without realizing it and without showing symptoms, therefore, is difficult. At the beginning of April about the U. S. Centers for Disease Control and Prevention said that probably 25 percent of those Infected showed no symptoms at all. The number of breast-feeding of Infected could be in truth much higher, shows a new study.
scientists at the Macquirie University Hospitals in New South Wales, Australia analyzed the data from cruise passengers, which were broken up in mid-March, from the coast of Argentina to a planned 21-day journey. Aboard: 128 Passengers, 95 Crew Members.
at that time, the world proclaimed health organization is already a global pandemic. People who had been in the past three weeks in countries with high infection rates, were not allowed to enter. In addition, all passengers fever was measured, also hand sanitizer were distributed on the ship.

investigation on a cruise ship: more Than 80 percent showed no symptoms
After the 8. Day showed, nevertheless, a first fever case had been provided to the vessel under the insulation. It introduced measures for infection control, the passengers were allowed to stay in their cabins. Staff came to act in contact with the sick pass, had to wear protective equipment.
Eight of the passengers and crew members eventually had to be due to Respiratory arrest in a hospital. 20. Day all of the remaining 217 passengers and crew were tested members of the Coronavirus.
The result: More than half, 59 percent, tested positive. Much more serious however: Only 19 percent of demonstrably Infected symptoms, 81 percent of them were not. This study led the scientists to suspect that silent infections occur much more often than previously thought.
ships, The spread of the Virus in isolated environments, such as cruise, had probably been “substantially underestimated,” said Alan Smyth, a physician at the University of Nottingham and editor of the journal “Thorax”, where the researchers published their results.
cruise-data should be in Exit strategies
It also be considered to draw conclusions on future loosening of the measures and the contact block could pull. “The countries move from the Lockdown out,” said Smyth more. “In fact, however, a much higher proportion of the population could be infected.”
Regardless of whether these people are already immune or not, we need urgent global data, in order to determine the actual Infected. Without reliable data it is difficult “to find a reliable estimate of the number of Sars-CoV-2-positive patients without symptoms.”
