Phase 2 (moderate)
The second phase of infection begins between the tenth and fourteenth
day. A protective immune response is impaired, the immune system was not
able to defeat the virus and this had a reproduction and an invasion of
the deep respiratory tract, as the lungs.
The hypoxic phase starts; in this phase hospitalization and oxygen
administration can be required.
Cardiac involvement and clotting problems could take place in this phase
and patients with underlying heart disease could have a greater risk of
entering the serious clinical picture. Laboratory tests show a decrease
in lymphocytes, an increase in transaminases and a moderate increase in
pro-inflammatory markers.
The treatment that could be indicated is a continuous use of anti-viral
drugs and, when the respiratory situation worsens, need to be started
the support of oxygen and/or use of anti-inflammatory drugs, antibiotics
and the administration of LMWH-(Low-molecular-weight-heparin) to prevent
thromboembolic events.
