Norte de Santander has already exceeded two thousand confirmed cases for COVID-19 and has more than 100 deaths due to this virus that has been affecting the entire world. However, despite the recommended measures to stop contagion, cases continue to rise because there are many myths on the subject and the population does not believe in the veracity of the virus, nor in the method of contagion.
The opinion He consulted the pediatrician Andrés Arias, an infectious disease specialist, and resolved several questions regarding the coronavirus.
He assured that it is very important to maintain social distance, wear face masks and have a habit of constant hand washing to avoid getting infected and having to go to extremes such as ICUs.
In addition, he said that the population has the solution in their hands, not only abiding by the recommendations, but being responsible when they believe they have the symptoms or believe they have had contact with someone infected. He stressed that isolating himself for a minimum of 10 days is key.
How do you see the panorama of the pandemic by COVID-19 in the city?
The condition is critical. We do not have beds available and we need greater citizen commitment. Surely in about four or eight weeks we will have a greater flow of patients and, therefore, it will be more complicated. We will need all available medical personnel to attend to the emergency.
How reliable are the results of a test? Is there a counter sample?
Basically it depends on the place where it is taken, the type of test that is done and the time it is done, ideally within the first 10 days. For example, if it is a PCR, you can detect a successful result in eight out of 10 patients. All samples are not 100 percent accurate, they always tend to have a margin of error.
How likely is a test to be spread by tampering?
As it is an open molecular test, it can be spread, however, the authorities in charge, before setting up a laboratory for this type of procedure, carry out a review with high quality standards, to avoid any subsequent inconvenience.
How long does it take for the virus to incubate?
It is a virus that, according to what has been studied, can take from three to five days, that is, fast.
After incubation of the virus, how many days do symptoms appear or start?
In 93 and 94 percent of people who have been infected, symptoms have occurred between the sixth and seventh day.
If the person has just been infected, how likely is the result to be positive?
It must be borne in mind that for there to be contagion, the person must have had close contact for more than 15 minutes, less than two meters and without face masks. And you have to wait at least seven days to have a successful test.
However, due to current circumstances, anyone who initiates mild symptoms should be considered positive and manage at home.
Are there various types of tests?
There are two that make a diagnosis: PCR and Viral Antigens, which are effective in the first days of the virus, after day eleven, tend to lose utility. There is also the serological test, which is done through the blood, it is not the most recommended unless there are symptoms.
Do city factors and sample preservation influence the test?
Yes. The samples must be in freezers at less than 70 degrees, if there is not a good conservation, the yield diminishes.
Can anyone test positive without being contagious?
Yes. We know that the asymptomatic is contagious as it is symptomatic, but if the condition is mild and 10 days pass from the test and a new one is done, even if it is positive, however, that does not indicate that at that time it is still contagious.
Are there false negatives?
It depends on the time in which the test is taken, the later it is consulted for the PCR and for the Antigens there is more possibility of false negatives, as with serology.
Which test is more reliable: nasal or serological?
Reliability is commensurate with the time the test is done and the symptoms that are experienced.
Is it true that clinics and hospitals receive money for every COVID-19 patient they serve?
Is not true. The virus exists, the disease also. No doctor or health personnel is given money for this, what’s more, many have become ill and even died as a consequence.
Why are there so many deaths if the case fatality is not high?
The case fatality rate is high in those who require critical care, and the age at which the virus is acquired depends on the fact that it is more aggressive in those over 60 years of age. We went from having an overall mortality of 3.5 or 4 percent to passing 35 and up to 55 percent in these patients.
How long does a vaccine take to market and for a virus like COVID-19, can it take the same process?
The time is according to the type of virus that is being treated. There are vaccines that have taken many years, there are even some diseases for which we have not yet been able to find vaccines. In the case of COVID-19, there are already many advanced trials in their clinical phases, but it can usually take two to six years for it to be released. However, as all systems are committed to making this vaccine, positive results have been achieved.
If after 20 days the test comes back with a positive result, do you still have the virus or not?
Perhaps there are still viruses in the body, but if it does not present a symptom or have not presented them, it is no longer infectious.
Can a test determine what stage the virus is in?
This statement is not entirely true, what does determine is whether you have the virus or not and that is related to the patient’s phase if he has symptoms, if he is in a critical phase or if he has no symptoms.
Can the virus cause negative effects on the neurological system?
Yes. It is something that with the passage of the virus has been demonstrated, but this is not only due to the virus, but when intensive care is required for any disease.
