- An R-value smaller than 1 means the disease is spreading slowly: Experts
- The bigger the number than 1, the faster the rate of spreading of disease
- India's R-value, calculated between September 25 & October 18, was 0.90
Mumbai: India’s R-value, which reflects how rapidly the coronavirus pandemic is spreading, has remained below 1 since September, suggesting that the infection rate is declining, according to a study. The Reproduction number or R refers to how many people an infected person infects on an average. In other words, it tells how ‘efficiently’ a virus is spreading. An R-value smaller than 1 means the disease is spreading slowly.

Conversely, if R is greater than 1, the number of infected people is increasing in each round – technically, this is what is called the epidemic phase. The bigger the number than 1, the faster the rate of spreading of the disease in the population.
According to figures calculated by researchers of the Chennai-based Institute of Mathematical Sciences, the R-value of top 10 states with most number of active cases was below 1 till October 18. However, some of the cities continue to show a rising number of active cases. Kolkata has an R-value over 1, perhaps “unsurprising” given the mass gatherings during the (recently-concluded) Durga Puja, said Sitabhra Sinha, who is leading the research. Bengaluru also has R-value over 1 — it has been so ever since mid-September — while the R-values of Chennai, Pune and Mumbai are just below 1.
The country’s R-value, calculated between September 25 and October 18, was 0.90. Between August 30 and September 3, the value was 1.11. It started declining since then — the R-value was 0.94 between September 4 and 7, 0.86 between September 11 and 15, 0.92 between September 14 and 19 and 0.87 between September 17 and 21, as per the study. After the brutal second wave of coronavirus between March to May this year, the daily COVID-19 cases have been on a decline.
On Tuesday, India logged 13,058 new coronavirus infections, the lowest in 231 days, according to the Union Health Ministry’s data. The daily rise in new coronavirus infections has been below 30,000 for 25 straight days and less than 50,000 daily new cases have been reported for 114 consecutive days now. The active cases comprise 0.54 per cent of the total infections, the lowest since March 2020, while the national COVID-19 recovery rate was recorded at 98.14 per cent, the highest since March 2020, the ministry said.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, that is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
