What is "Coronavirus"?
Coronavirus (ICD10) is a family of viruses that cause respiratory infections. The new coronavirus agent was discovered on 12/31/19 after cases reported in China. It causes the disease called coronavirus (COVID-19).
The first human coronaviruses were isolated for the first time in 1937. However, it was in 1965 that the virus was described as coronavirus, due to the profile in microscopy, resembling a crown.
Most people become infected with the common coronaviruses throughout their lives, with young children being more likely to become infected with the most common type of the virus. The most common coronaviruses that infect humans are alpha coronavirus 229E and NL63 and beta coronavirus OC43, HKU1.
Why is the name "Coronavirus"?
Because this family of viruses has the characteristic of looking like a crown.
What is the incubation period for the Coronavirus?
Incubation period is the time it takes for the first symptoms to appear since coronavirus infection, which can be 2 to 14 days.
What is the transmission period of the Coronavirus?
Generally speaking, viral transmission occurs only as long as symptoms persist Viral transmission is possible after symptoms resolve, but the duration of the period of transmissibility is unknown for coronavirus. During the incubation period and asymptomatic cases are not contagious.
What is the source of Coronavirus infection?
Most coronaviruses usually 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 the coronavirus (COVID-19) is still unknown.
What are the types of Coronavirus?
The types of coronaviruses known so far are:
Alpha coronavirus 229E and NL63.
Beta coronavirus OC43 and HKU1.
SARS-CoV (causing Severe Acute Respiratory Syndrome or SARS).
MERS-CoV (cause of Middle East Respiratory Syndrome or MERS).
SARS-CoV-2: a new type of virus of the coronavirus agent, called COVID-19, which emerged in China on December 31, 2019.
Some coronaviruses can cause serious illness with significant public health impact, such as Severe Acute Respiratory Syndrome (SARS), identified in 2002, and Middle East Respiratory Syndrome (MERS), identified in 2012.
