Corona research has come to new findings: At a certain stage of the disease, the infected transmit a particularly large number of viruses.
The
Corona
* -Research has produced new results.
During this
time
, people
infected
with
corona
are
most contagious.
Are our current
test
method for effective
infection containment
.
Kassel - The
fact
that
people
quickly
become infected
with the
corona virus is
shown by the constantly high number of infections.
However
, it was not yet known
within what
time
infected people are really contagious.
The latest findings from the
science
that question cleared up now.
The
researchers
are also questioning the current
test
method.
New corona findings: During this time, infected people are contagious
A
study
by researchers from
Scotland
examined the
time when corona
infected people are most contagious.
The research team from the University of St. Andrews came to the
result
that people with the
Corona
-
virus
infected, occur in the first 5 days after the first
symptoms
probably are most contagious.

New knowledge could also be gathered about the duration of the risk of infection.
According to the scientists around Muge Cevik, after
9 days there are
probably no more infectious viruses in a patient's body.
This means that from this point on the
patients are
no longer contagious.
The
researchers
came to their results
by
evaluating
data from 79
corona studies
.
Infectious
viruses
could not be found
in any of the samples taken 9 or more days after the onset of
symptoms
.
Corona study: The viruses can be detected in the body for a long time
The
corona virus
could be detected for a very long time
in some samples
.
The longest evidence in the
study
was found in a stool sample after 126 days.

On average, the
corona viruses
could be detected for between 14 and 17 days, albeit no longer infectious.
This also
applies to the
PCR tests
customary
in
Germany
, which are often used in Germany.
Corona tests: PCR follow-up tests could be omitted in the future
On the basis of PCR follow-up tests it is currently intended to determine whether the
person is
still contagious.
The genetic material of
SARS-CoV-2 is
detected in
the
PCR tests
.
This means that even if the
person
concerned
no
longer carries
any infectious
viruses
, the
test
can be
positive.
The
researchers
from
Scotland
therefore suggest that with less severe courses, it is assumed that the person is no longer infectious after 10 days.
It
is currently unclear
whether this
will soon be applied
in
Germany
.
New findings about Corona: What is important now
The new findings from Scotland show one thing above all:
Isolation
from the first
symptoms
is very important in order to
contain the
further spread of the
corona virus
.
The risk of infection is highest
especially in the first
phase of
the
illness
, i.e. in the first 5 days.
This also requires further clarification of the various symptoms of the disease.
The research team also points out that many people are currently unable to isolate themselves adequately due to their living conditions.
The team suggests that governments
could provide
housing
as
an alternative
to improve this situation.
