Since the first cases appeared, we have been able to observe a significant evolution of the virus. Although in the first place hospitals collapsed due to the high amount of patient need for the use of respirators and a high number of deaths. At present, outbreaks are characterized by a diverse and mostly less severe symptomatology .
Its standard clinic : characterized by a rather nonspecific triad of fever, cough, and dyspnea. There are other associated symptoms such as fatigue / myalgia (muscle pain), headache, nausea / vomiting, odynophagia (pain in the pharynx), dysgeusia (altered sense of taste) and hyposmia (partial loss of smell), among others.
Patients admitted to hospital : Most have presented a picture of bilateral pneumonia with ground glass opacities on chest CT.
Blood tests: most people have shown lymphopenia (reduced white blood cell count) and a prolonged PT (prothrombin time), in addition, in some cases an increase in LDH (lactate dehydrogenase) has been observed.
Symptoms are very varied, creating mild, moderate or severe symptoms including pneumonia, Acute Respiratory Distress Syndrome (ARDS), sepsis and septic shock. The patients who present a severe picture of the disease presents 10-15 days from the onset of symptoms until they present respiratory failure.
