Unfortunately, we faced a pandemic provoked by Covid-19 that caused irreparable losses. The scientific community has made many efforts to search for treatments in the last two years, from drugs to treat severe clinical pictures to vaccines, which have effectively prevented the aggravation of symptoms in infected people, thus, protecting the world's population.
We should note that the main route of transmission of SARS-CoV-2, as this virus is known, occurs from person to person. It happens when particles of different sizes, such as droplets or aerosols, are expelled into the environment by infected people when coughing or sneezing, and it directly contacts the eyes, nose, or mouth.
It is vital to consider some preventive measures to control the spread of Covid-19 since the virus is still circulating. For example, we should keep in mind to:
Wear a facemask in public indoor areas or areas with a high probability of SARS-CoV-2 virus transmission.
Avoid close contact with sick people.
Avoid touching your eyes, nose, and mouth.
Stay home when sick.
Cover your mouth or nose when coughing or sneezing.
Regularly clean objects and surfaces that you touch often.
Wash your hands frequently with soap and water.
For this reason, timely diagnosis and identification of the presence of the virus in our body are essential to avoid contact with other people and continue spreading the virus in the places we frequent.
How can we discover that we have been infected with Covid-19? Detection tests developed by scientists and researchers are essential for identifying the virus in our bodies. There are reliable and accurate techniques such as real-time polymerase chain reaction (RT-PCR) and antigen tests.
In addition, these tests let you know if you have been contaminated quickly. This type of test is known as a "viral" test because it seeks to detect viral infection. Antigen tests are fast, effective, safe, and inexpensive tests that allow you to determine if you have been infected, with results in a few minutes.
