On the origin of a virus that created havocs across the globe, devastated world’s economy, affected lives of billions, killed millions, and still counting.
From a premature victory declaration over COVID-19, now India is under the ruthless grip of the enemy in new disguise. After curtailing to less than 10,000 daily cases towards the end of the first wave, now a staggering over 350,000 daily cases and nearly 3200 daily deaths! Neglect on mitigation measures, worse policies and inadequateContinue reading “A tsunami of variants?”
Viruses mutate when they make more copies in host cells- there is nothing unusual about it. Mutations are changes in genetic material (DNA or RNA) that may cause changes in the coded proteins. These processes are not something bizarre happening to SARS CoV2 virus, such coping errors happen when genetic materials (DNA or RNA) are replicated.Continue reading “Variants Of Concern- a nightmare coming true?”
It’s been more than a year now, that we came to know about the SARS CoV2 virus and the COVID19 disease. In the absence of an effective antiviral drug for this pandemic, vaccine is the way out. Several vaccine candidates came out with remarkably high efficiency from the clinical trials in a record time andContinue reading “Beginning of the end!”
SARS-CoV2, a tiny string of RNA made of mere 30 thousand molecules (ribonucleotides) wrapped in a membrane stolen from the host, changed the behavior of us humans! Today, we walk around wearing masks, do frequent hand washings, soak in sanitizers, we feel nervous if someone next coughs or sneezes, and are socially distanced from otherContinue reading “A virus that changed us!”
Along with a viral outbreak, many conspiracy theories emerge-it is unavoidable. Conspiracy theories flourish and spread even more virally than the viral disease. More interestingly, such conspiracy thinking may not disappear even after the outbreak subsides. If you look at the history of AIDS, vaccines, or any novel therapeutic interventions in the past, you mayContinue reading “COVID-19 origin conundrum”
Previous blog ´War against a virus´ was on the general features of the virus. Here I try to feed the information regarding the virus (SARS CoV-2) and the disease it causes (COVID-19), which may help you to understand better this hidden enemy. Science is on the learning curve for this novel virus. For that reason,Continue reading “Briefings on the hidden enemy”
When you hear the word ´virus´, unpleasant memories rush to your mind. It could be the painful memories of childhood chicken pox or about exhaustive viral-fever days or about scenes from Hollywood movies like Outbreak and Contagion. Not all viruses are bad though, some are beneficial to us (will discuss that topic later). These daysContinue reading “War against a virus!”
