Are saliva tests just as effective as nasal swabs to diagnose COVID-19?

Saliva testing for coronavirus disease 2019 (COVID-19) is as effective as the standard nasopharyngeal tests, according to a new study by investigators at McGill University.

Is the COVID-19 swab test painful?

COVID-19 swab testing has not been shown to cause major injury to the nose or sinuses. When COVID-19 testing began, it was believed that nasal swabs needed to be inserted 3-5 inches into the nose to reach the back of the nasal cavity. This can be very uncomfortable, causing a small proportion of people to gag, cough, bleed from the nose, or even faint. However, newer tests use a type of swab that is much shorter in length but just as effective. The test you receive may depend on the availability of these different swabs.

How is the COVID-19 nasal swab test performed?

A fluid sample is collected by inserting a long nasal swab (nasopharyngeal swab) into your nostril and taking fluid from the back of your nose or by using a shorter nasal swab (mid-turbinate swab) to get a sample.

How long does it take to get results for a Labcorp COVID-19 swab test?

For the test to determine if you had COVID-19 (blood/antibody test): Average delivery of result is 1-3 days from the date of specimen pickup.

Are smokers more likely to develop severe disease with COVID-19?

Tobacco smoking is a known risk factor for many respiratory infections and increases the severity of respiratory diseases. A review of studies by public health experts convened by WHO on 29 April 2020 found that smokers are more likely to develop severe disease with COVID-19, compared to non-smokers.

Can the coronavirus disease spread through feces?

The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.

Are CT scans helpful for diagnosing COVID-19?

Along with laboratory testing, chest CT scans may be helpful to diagnose COVID-19 in individuals with a high clinical suspicion of infection.

Can the coronavirus disease be transmitted through water?

Drinking water is not transmitting COVID-19. And, if you swim in a swimming pool or in a pond, you cannot get COVID-19 through water. But what can happen, if you go to a swimming pool, which is crowded and if you are close to other the people and if someone is infected, then you can be of course affected.

How long does the virus that causes COVID-19 last on surfaces?

Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.

What is the difference between people who have asymptomatic or pre-symptomatic COVID-19?

Both terms refer to people who do not have symptoms. The difference is that ‘asymptomatic’ refers to people who are infected but never develop any symptoms, while ‘pre-symptomatic’ refers to infected people who have not yet developed symptoms but go on to develop symptoms later.

Can COVID-19 cause severe disease?

While COVID-19 is spreading rapidly, most people will experience only mild or moderate symptoms. That said, this coronavirus can cause severe disease in some people.

Can I get COVID-19 from eating fresh foods, like fruits and vegetables?

There is currently no evidence that people can catch COVID-19 from food, including fruits and vegetables. Fresh fruits and vegetables are part of a healthy diet and their consumption should be encouraged.

Does UV light kill COVID-19?

Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).

Has COVID-19 been detected in drinking water supplies?

The COVID-19 virus has not been detected in drinking-water supplies, and based on current evidence, the risk to water supplies is low.

How long should I self-quarantine if I have been exposed to COVID-19?
