ATIVIDADE 01.
SOBRE CORONAVÍRUS
Clinical
manifestations
Coronaviruses
in ordinary humans cause mild to moderate respiratory infections of short
duration. Symptoms can involve runny nose, cough, sore throat and fever. These
viruses can sometimes cause infection of the lower respiratory tract, such as
pneumonia. This condition is more common in people with cardiopulmonary
diseases, with compromised immune systems or in the elderly.
Incubation
period
From
2 to 14 days
Transmissibility
Period
In
general, viral transmission occurs only as long as symptoms persist Viral
transmission is possible after resolution of symptoms, but the duration of the
transmissibility period is unknown for SARS-CoV and MERS-CoV. During the
incubation period and asymptomatic cases are not contagious.
Interhuman
transmission
All
coronaviruses are transmitted from person to person, including SARS-CoV, but
without sustained transmission. Regarding the MERS-CoV, the WHO considers that
there is currently well-documented evidence of person-to-person transmission,
but without evidence that sustained transmission occurs.
Transmission
Mode
In
general, the main form of transmission of coronaviruses is through close
contact * from person to person.
*
Definition of close contact: Anyone who cared for the patient, including health
professionals or family members; who has had physical contact with the patient;
stayed in the same place as the sick patient (eg, lived together or visited).
Infection
source
Most
coronaviruses generally infect only one animal species, or at least a small
number of closely related species. However, some coronaviruses, such as
SARS-CoV, can infect people and animals. The animal reservoir for SARS-CoV is
uncertain, but appears to be related to bats. There is also the likelihood of
an animal reservoir for MERS-CoV that has been isolated from camels and bats.
