Frequently Asked Questions and Answers
Can I have a negative COVID test result and later a positive result?
A negative result means the person was not infected with COVID 19 at the time. In the early stages of infection, the virus may not be detected. This does not mean that person can contract the virus in the future and test positive for COVID-19.
What are the results I can get from the COVID-19 Test?
Positive test: Indicates that there is enough viral load to exceed the fluorescence threshold that the test gives as positive. You have the virus. Negative result: It indicates that there is no virus in the sample obtained, therefore, there is no copied DNA, therefore the threshold is not exceeded and the patient is free of the virus, does not suffer from it. False positives or negatives: In some cases, sample deterioration or contamination may alter the results. PCR tests work to detect infection, but do not indicate whether or not someone has passed the disease and recovered. In this case, rapid tests based on the detection of antibodies would be useful.
How is the procedure for taking the sample?
The clinical samples recommended for these analyzes are samples of the upper respiratory tract, by taking a nasopharyngeal and oropharyngeal exudate. To do this, two swabs or swabs must be collected, one nasal (where the swab is introduced into both nostrils, so that the sample is collected in the nasal pharynx, and rotated two or three times to have a good shot) and another from the throat (the swab should be rubbed by the back of the throat and rubbed, Avoiding touching the epiglottis so as not to cause vomiting of the patient) and introducing them into the culture medium for viruses, once inside the tube, it must be shaken to achieve a good dispersion of the exudate obtained. Nasopharyngeal and oropharyngeal smears should be placed in the same tube to increase the viral load. After collection, samples should arrive at the laboratory as soon as possible, and proper handling should be carried out during transport. Samples that can be quickly delivered to the laboratory can be stored and shipped at a temperature of 4°C. If the delivery time for airway samples to the laboratory is expected to be longer than 72 hours, it is particularly desirable to store them in dry ice at -80 °C.
What is the COVID-19 test?
The technique used to detect coronavirus is PCR. This method allows a small amount of DNA to be copied millions of times, so that there is enough to analyze it by the fluorescent light emitted by the sample after adding dyes to it that bind to the viral DNA while it is being copied.
What should I do if I have symptoms?
People who have any of the following respiratory symptoms (fever, cough, and shortness of breath) and live or have been in an area of community transmission in the previous 14 days, or have had close contact in the previous 14 days with a person who is a probable or confirmed case, should stay home and contact their community health services.
How can I prevent Covid-19?
Avoid close contact with people suffering from acute respiratory infections and/or fever and cough. Avoid close contact with other people (kisses, hugs, greetings …). Wash your hands frequently with soap and water or hydroalcoholic gel (containing a 60% alcohol >base) for at least 20 seconds, especially if there has been any contact with other people, or if you have coughed or sneezed. Dry your hands with single-use paper. Avoid touching your mouth, nose, and eyes. Cover your mouth when coughing or sneezing with a tissue, or over your bent elbow. Frequently clean frequently touched objects and surfaces such as knobs, handles, doors, tables, countertops, computers, phones, etc., disposable towels or a clean cloth sprayed with cleaning liquid should be used. Avoid sharing plates, cutlery, glasses, towels, and other objects where you may touch a person’s saliva. Keep a distance from other people of at least one and a half or two meters. Use a mask if you need to leave the house for some reason of highest priority. Stay home and isolated when sick.
How does the virus spread?
The new coronavirus, COVID-19 is spreading from person to person through flugge droplets that are expelled from the oral and nasal passages when talking, coughing or sneezing and that reach distances of 1.5-2 meters. These droplets fall directly on people.
Who are the groups most vulnerable to Covid-19?
The main most vulnerable groups are those over 60 years of age, and people suffering from previous pathologies such as high blood pressure, diabetes, cardiovascular diseases, chronic lung diseases, immunodeficiency and cancer.
How long do COVID-19 symptoms last?
In general, from the appearance of symptoms until healing are two weeks in mild cases and up to 6 weeks in acute or severe cases.
When do COVID-19 symptoms appear?
The incubation period is the time between infection with the virus and the onset of symptoms of the disease. Most estimates of the incubation period for COVID-19 range from 1 to 14 days, and are generally around 5-6 days.
What are the symptoms of COVID-19?
In general, the main symptoms of coronavirus infections are cough, sore throat, fever, shortness of breath, headache, chills, and malaise. About 80% of infected people have mild symptoms mainly in young adults and children. In more severe cases, the infection can cause pneumonia, severe shortness of breath, kidney failure, and even death. Complications usually occur in elderly people or those suffering from a chronic disease such as diabetes, hypertension or kidney or cardiovascular problems.
Are COVID-19 and SARS the same?
No, they are similar, but not the same. Both belong to the coronavirus virus family but are different. The case fatality rate of SARS is higher but less infectious than COVID 19. In fact, no SARS outbreak has been recorded since 2003.
What are coronaviruses?
Coronaviruses are a family of viruses that were discovered in the 60s but whose origin is still unknown. Different types cause different illnesses, from a cold to severe respiratory syndrome (a severe form of pneumonia). Many coronaviruses are not dangerous and can be treated effectively. In fact, most people contract a coronavirus at some point in their lives, usually during their childhood. Although they are more frequent in autumn or winter, they can be purchased at any time of the year.
