With ~3 lakh new Covid cases coming every day in wave 2 in India, let’s answer some of the questions many of you have regarding the second.
Crux of the Matter
The new strain is escaping the RT-PCR test, which is considered a gold standard test.
Many cases have come to fore, where a patient has symptoms of Covid-19 but get RT-PCR -ve report. So a CT-scan is used to confirm the infection.Dr Sarman Singh, AIIMS Bhopal director
Covid-19 Wave 2 Symptoms
This time we have witnessed more cases of breathlessness while in the last wave, symptoms like dry cough, joint pain, headaches were more.Dr Bhargava, ICMR Chief
After Getting The Shot, Can You Be Covid +ve?
Yes. As per CDC, after the first shot, you have 50% immunity. The 2nd shot gives 95% immunity. It then takes 1-2 weeks for maximum protection to kick in.
Even then you can contract Covid with less severity, i.e either you will be asymptomatic or have mild symptoms.
Number of people contracting Covid after getting vaccine in India are given below:
What Is The Primary Mode Of Transmission?
As per latest CDC findings, the principal mode by which people are infected with SARS-CoV-2 is through exposure to respiratory droplets carrying infectious virus. The risk of being infected through contact with contaminated surfaces or objects (fomites) is considered low.
Can The Virus Survive On Surfaces?
Researchers suggest a 99% reduction in infectious SARS-CoV-2 and other coronaviruses can be expected under indoor environmental conditions within 3 days on common non-porous surfaces like stainless steel, plastic, and glass.
Misinformation On Twitter
medRxiv did a detailed analysis of COVID19 vaccine disinformation executed by tracing all postings of #AstraZeneca over “blood clot” time frame. The paper said misinformation was spread by powerful individuals, conspiracy websites, state-owned media outlets, as well through co-tweeting bot network.
Negative News Coverage By US Media
As per a recent study, 87% of Covid coverage in national US media last year was negative. The share was 51% in international media, 53% in US regional media and 64% in scientific journals.
- RT-PCR has risen to become the benchmark technology for the detection and/or comparison of RNA levels. Due to its simplicity, specificity and sensitivity, RT-PCR is used in a wide range of applications from experiments as simple as quantification of yeast cells in wine to more complex uses as diagnostic tools for detecting infectious agents.
- As of 21 April 2021, more than 143 million cases have been confirmed, with more than 3.04 million deaths attributed to COVID-19, making it one of the deadliest pandemics in history.
- On 11 February 2020, the World Health Organization (WHO) named the disease “COVID-19”, which is short for coronavirus disease 2019.
