Good Lifestyle

Imagine last night you have developed a nose that flows and a sore throat. When you woke up this morning, you started coughing and doing fever. In the past year, your mind would have immediately jumped toCOVID-19 [Feminine. But if you are already completelyvaccinatedYou may be wondering: Should I still be tested for Covid-19?

As a doctor of infectious diseasesI am often asked this question. The answer is yes. If you have symptoms of COVID-19, you should be tested for Covid-19, even if you are completely vaccinated. You will not be at high risk of hospitalization or serious illness, but if you are infectedcan pass the virus to a non-vaccinated person, who could then become very sick.

Vaccines work but are not 100% effective

Researchers have developed someIncredible Covid-19 vaccines over the past year. The high efficiency of these vaccines in the closely controlled environment of clinical trials is their effectiveness in real life. MRNA vaccines manufactured by Pfizer and Moderna remainMore than 90% effective to prevent hospitalization or death.

However, this does not mean that you have the same degree of protection against infection.

The latest searches believe that mRNA vaccines offer70% to 85% protection against infected being at all. It is impossible to know if a person is completely protected or could always develop a mild case if exposed to the coronavirus.

If you have occurred, you can still broadcast the virus. And that's why the test is always important.

What is a revolutionary case?

When a person is infected with the coronavirus after being entirely vaccinated, it is called a revolutionary case. Revolutionary cases demonstrate a basic principle of infectious disease - that a person is infected or not dependent on the balance between two factors: the intensity of exposure and immune jurisdiction.

Intensity of the exhibition Applies to closing the closure of a person not infected with a highly infectious individual virus speaking and how long the two people are in contact. Immune jurisdiction concerns the inherent body protection against Covid-19. Unvaccinated individuals who have never been infected with coronaviruses have no protection - this is a totally new virus after all - while the entirely vaccinated people will be much more protected.

According to the CDC, on April 30, 2021, there had been a total of10 262 SARS-COV-2 vaccine drills infections known in the American states and territories. These are usually asymptomatic or slightly symptomatic cases, and most do not result in hospitalization. Revolutionary cases will continue to occur, and although these people areless likely to spread coronaviruses to others only unvaccinated individuals,They can probably probably.

And what about SARS-COV-2 variants? Well, the world was lucky that the mRNA vaccinates in particularAllow significant protection against all major variants which are emerged so far. But it is quite possible that at any time hasThe coronavirus strain could mutated andpartially or completely escape the protection against vaccines. It's still another good reason to get tested if you feel sick.

As vaccination rates rise and the daily number of cases falls in the United States and other countries it is alsoimportant to keep a narrow eye on the coronavirus. Covid-19 tests allow officials to keep track of the amount of virus in a community and positive test results can help people in quarantine before unconsciously spreading the virus. So, yes, please do you test if you have symptoms, even if you are fully vaccinated.
