Covid-19 cases

A new study published in UK based medical journal ‘The Lancet Digital Health’ on Thursday claimed that early Covid-19 symptoms varies between age groups and also between men and women.

The study was carried out by the researchers at King’s College in London using data from the self-reported ZOE Covid Symptom Study app. The researchers studied 19 symptoms, including the most common ones such as a persistent cough and loss of smell, as well as abdominal pain and blisters on the feet.

The researchers told that the study was aimed to estimate the probability of an individual being infected with SARS-CoV-2 (Covid-19) on the basis of early self-reported symptoms to enable timely self-isolation and urgent testing. Model performance to predict Covid-19 positivity was compared in terms of sensitivity, specificity and area under the receiver operating characteristic curve (AUC) in the test set, they said.

The findings of the study suggests that loss of smell was not significant in people aged over 60 while it was not at all relevant in people over 80. But these older age groups were more likely to suffer diarrhoea, the study suggests.   

Apart from this, a persistent cough had a higher relevance to detect Covid-19 and chills or shivers had a lower relevance in the age group 40 to 59 compared with individuals 80 years or older.

As per the findings, chest pain, unusual muscle pain, shortness of breath and loss of smell were the most relevant features for people aged 60 to 70.

On the gender variations, men were most likely to report shortness of breath, fatigue, chills and fever while women were more likely to report loss of smell, chest pain and a persistent cough.

The interpretation of the study concludes that early detection based on this model is crucial to contain the Covid spreading and efficiently allocate medical resources.

Delhi's air quality

Delhi woke up to hazardous air conditions on Tuesday as dense smog covered large parts of the national capital, pushing the Air Quality Index (AQI) into the ‘severe’ category across several locations. Poor visibility and rising health concerns marked yet another spell of extreme pollution in the city.

Data from the Central Pollution Control Board (CPCB) showed the overall AQI in Delhi touching 413 in the morning, placing it firmly in the ‘severe’ bracket. Several areas across the National Capital Region (NCR) reported alarming pollution levels, indicating a widespread deterioration in air quality.

Pollution hotspots report hazardous readings

Some of Delhi’s major pollution hotspots recorded extremely high AQI levels. Anand Vihar topped the list with an AQI of 466, followed by Ashok Vihar at 444 and Chandni Chowk at 425. These areas remained in the ‘severe’ category, posing serious health risks, especially for children, the elderly and those with respiratory conditions.

Even central parts of the city were not spared. India Gate, Kartavya Path and the Rashtrapati Bhavan area were shrouded in toxic smog, with AQI levels around 384, categorised as ‘very poor’.

GRAP stage-IV measures enforced across Delhi-NCR

In response to the worsening situation, the Commission for Air Quality Management (CAQM) enforced all actions under GRAP Stage-IV across Delhi-NCR. As part of these emergency measures, truck-mounted water sprinklers were deployed to suppress dust and reduce particulate matter in the air.

As per AQI standards, readings between 401 and 500 fall under the ‘severe’ category, while levels above 300 are considered ‘very poor’, highlighting the seriousness of the current conditions.

Delhi government reviews pollution control steps

The Delhi government has reiterated its commitment to tackling rising pollution levels with strict enforcement measures. Chief Minister Rekha Gupta stated that a zero-tolerance policy will be followed against all sources contributing to air pollution in the capital.

A high-level review meeting was held at the Delhi Secretariat to assess existing measures and take further decisions. The meeting focused on enforcing Pollution Under Control (PUC) norms without any relaxation, exploring pooled and shared electric bus services across Delhi-NCR, issuing fresh guidelines for e-rickshaws, and rationalising Delhi Transport Corporation (DTC) bus routes.

Senior officials from the Environment and Transport Departments, the Delhi Pollution Control Committee (DPCC), Public Works Department (PWD) and Delhi Traffic Police, along with Environment Minister Manjinder Singh Sirsa, attended the meeting to finalise immediate and long-term steps to address the pollution crisis.

Rahul Gandhi alleges institutional bias, questions electoral system during Berlin address

Rahul Gandhi alleged that India’s institutions and electoral system have been weaponised to favour the BJP, remarks that sparked a strong political response.

Rahul-Gandhi

Leader of the Opposition in the Lok Sabha, Rahul Gandhi, has said that India’s institutional framework is facing a serious challenge and has been used to favour the ruling BJP. Speaking during an interaction at the Hertie School in Berlin, Gandhi questioned the functioning of key institutions and the electoral machinery, remarks that triggered a sharp political response from the BJP.

Gandhi said the Congress believes there is a problem with the electoral system and alleged that several institutions have been captured. Referring to investigative agencies, he claimed that bodies such as the CBI and the ED have been used as political tools. According to him, cases filed by these agencies overwhelmingly target those opposing the BJP, while leaders from the ruling party face none.

He also pointed to what he described as a stark financial imbalance between the BJP and the opposition, claiming a funding ratio of 30:1. Gandhi said this disparity reflects how institutions are being used to consolidate political power.

Opposition strategy and INDIA alliance

The Congress leader said merely pointing out problems in elections is not enough and stressed the need for the opposition to build a system of resistance that can effectively counter the ruling party. He added that the challenge now goes beyond electoral contests and is about presenting an alternative vision for the country.

On the INDIA alliance, Gandhi said the unity among opposition parties is rooted in their rejection of the ideological position of the RSS. While acknowledging that tactical contests between alliance partners will continue, he said they remain united when it comes to opposing laws they disagree with and working together in Parliament.

BJP hits back at remarks abroad

Gandhi’s comments delivered overseas drew a strong reaction from the BJP. Party president and Union minister JP Nadda accused him of speaking against India while Parliament is in session and claimed that he was undermining the country’s image at a time when the Prime Minister is receiving global recognition.

BJP spokesperson Shehzad Poonawalla also criticised Gandhi, alleging that he routinely travels abroad to defame India. He accused the Congress leader of making misleading claims about the country’s institutions and economic activity while praising China.
