COVID-19 herd immunity: Current status

September 14, 2020 | News

Herd immunity is a key concept for epidemic control, which states that only a proportion of a population needs to be immune to an infectious agent for it to stop generating large outbreaks. We can achieve herd immunity through two strategies: by overcoming natural infection or through vaccination.

Little risk from dental aerosol procedures: 10 minutes gap is enough between two procedures

September 12, 2020 | News

We summarize all the latest pieces of evidence on dental aerosol procedures. We also trace the evidence back to 2003 SARS times when the aerosols were studied first. Despite weak evidence, dental aerosol-generating procedures have been termed risky.

First clinical trial: Vitamin D prevents Covid-19 complications in hospitalized patients

September 7, 2020 | News

A lot has been written on the role of vitamin D in the prevention & management of SARS-CoV-2 infection & COVID-19 disease. Interest in Vitamin D therapy has increased multifold after the recent bradykinin hypothesis successfully answered the questions that had been left unanswered by the cytokine storm hypothesis. The bradykinin hypothesis also proposed that Vitamin D therapy may control the bradykinin storm. However, the literature lacked a clinical trial in this regard. This article covers the results of a preliminary trial that has shown promising results with Vitamin D therapy in preventing complications in hospitalized Covid-19 patients.

‘Mask Mouth’- a novel threat to oral health in the COVID era – Dr Pooja Muley

August 26, 2020 | News

Today the use of face masks has become necessary and ubiquitous due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Even though a face mask protects the user from SARS-CoV-2 infection, it has certain adverse effects. One of the new and recently noticed side effect is on the oral health of the wearer known as ‘Mask Mouth’. This includes symptoms like caries, gingivitis, halitosis, candidiasis and angular cheilitis. But a positive aspect of the mask-mouth is that it can be easily prevented and treated. In this article, we will see this new phenomenon, its aetiology, symptoms and prevention.

Cycle Threshold (Ct) value of RT-PCR can tell us if a SARS-CoV-2 infected person can spread disease

August 24, 2020 | News

Currently, all SARS-CoV-2 detection measures make use of RT-PCR test, and its results are generally reported as either positive or negative, which tells us if a person is infected. However, to contain the pandemic, what we need to know is whether that person is infectious or in other words, 'can he spread the disease?' It's important to know that the RT-PCR test does provide an additional measure of the viral load in the sample. This reading is called the cycle threshold (Ct) value. Evidence suggests that reporting this Ct value (calculated viral load) can assist in a better interpretation of the condition, and also in taking clinical decisions.

Humans develop robust immune response & memory that may provide lasting protection against Covid-19

August 21, 2020 | News

One of the most critical questions the world is waiting for an answer is if the human body can mount a protective response that provides a lasting immunity against SARS-CoV-2. This understanding is crucial to the success of vaccines, the successful return of recovered patients to their pre-pandemic lifestyle, and also, how readily the world can overcome the fear of pandemic spread.

First direct evidence: SARS-CoV-2 neutralizing antibodies protect against re-infection in humans

August 18, 2020 | News

Vaccine development against SARS-CoV-2 would be greatly facilitated by the identification of immunological parameters that correlate with protection in humans. However, to date, most studies on protective immunity have only been performed in animal models and correlates of protection have not been established in humans. This study provides the first direct evidence that SARS-CoV-2 neutralizing antibodies protect against SARS-CoV-2 re-infection in humans.

ORF8 & ORF3b antibodies: Accurate serological markers of early & late SARS-CoV-2 infection

August 18, 2020 | News

The currently available SARS-CoV-2 antibody tests with their traditional serological approaches just tell us - yes or no, which has resulted in an underestimation of asymptomatic and mild infections. The next-generation serologic tests with a broader landscape of antibody responses to a wide range of viral proteins may help us establish the timing of infections too. This editorial describes a recent study (Nature, 17th Aug 2020) that gives an idea about the future of antibody testing in Covid-19.
