Coronavirus patients develop Neutralising Antibodies

A new study in Pune has revealed that nearly 85% of the people who had been found infected with novel coronavirus in a serosurvey had developed neutralising antibodies.

Immunity from a disease-causing virus comes from what are known as “neutralising” or “protective” antibodies.

Neutralising antibodies, like other antibodies that are created to fight the disease, are proteins.

These are a small subset of the disease-specific antibodies that are generated once an infection has occurred.

The neutralising antibodies become special because they have the ability to prevent the entry of the same virus inside human bodies in the future. 

The other antibodies help in fighting off the virus once the infection has already happened.


Delirium: One of the symptoms for older Covid-19 patients 

A new study supports evidence that delirium can predict coronavirus infection in older patients who show no other typical symptoms of Covid-19.

 Delirium is a serious disturbance in mental abilities that results in confused thinking and reduced awareness of the environment. 

The start of delirium is usually rapid — within hours or a few days.

Delirium can often be traced to one or more contributing factors, such as a severe or chronic illness, changes in metabolic balance (such as low sodium), medication, infection, surgery, or alcohol or drug intoxication or withdrawal.

Delirium and dementia

Dementia and delirium may be particularly difficult to distinguish, and a person may have both. 

Onset: The onset of delirium occurs within a short time, while dementia usually begins with relatively minor symptoms that gradually worsen over time.

Attention: The ability to stay focused or maintain attention is significantly impaired with delirium. A person in the early stages of dementia remains generally alert.

Fluctuation: The appearance of delirium symptoms can fluctuate significantly and frequently throughout the day. While people with dementia have better and worse times of day, their memory and thinking skills stay at a fairly constant level during the course of a day.


Five technologies recommended in Drinking Water and Sanitation to provide Field Level Solutions to the States

A multi-disciplinary Technical Committee in the Department of Drinking Water and Sanitation, Ministry of Jal Shakti has recommended five technologies in Drinking Water and Sanitation to provide Field Level Solutions to the States.

The Ministry of Jal Shakti gives importance to the infusion and deployment of innovative technological solutions to realize the objective of the Jal Jeevan Mission to provide Functional

Household Tap Connection to every rural home by 2024.

 The first technology recommended is Grundfos AQpure, a solar energy based water treatment plant based on ultra-filtration.

The Second is Janajal Water on Wheel, an IoT based electric vehicle based on GPS location to enable delivery of safe water to the doorstep of households.

Another technology is Presto Online Chlorinator, a non-electricity dependent online chlorinator for disinfection of water for removal of bacterial contamination.

Johkasou technology recommended is an inbuilt sewage and Kitchen and bath water treatment system having advanced anaerobic-aerobic configuration that can be installed underground.

The last innovative technology is FBTec®, a site assembled in a decentralised sewage treatment system using fixed filter media.

 Jal Jeevan Mission

It envisages supply of 55 litres of water per person per day to every rural household through Functional Household Tap Connections (FHTC) by 2024.

It focuses on integrated demand and supply-side management of water at the local level.

Creation of local infrastructure like rainwater harvesting, groundwater recharge and management of household wastewater for reuse, would be undertaken in convergence with other government programmes/schemes.

It is based on a community approach to water and includes extensive Information, Education and Communication as a key component of the mission.

Funding Pattern: The fund sharing pattern between the Centre and states is 90:10 for Himalayan and North-Eastern States, 50:50 for other states, and 100% for Union Territories.
