Hot weather theory falls flat, coronavirus more potent in India post-summer

Agencies
July 5, 2020

The deadly coronavirus that entered India while there was still nip in the air has beaten rising mercury, humid conditions, unique Indian genome and has entered monsoon season with more potency as fresh cases are only breaking all records in the country.

India recorded a single-day spike of record 24,850 new coronavirus cases on Sunday, taking its total tally to 6.73 lakh corona-positive cases.

Top Indian microbiologists were hopeful in March that after the 21-day lockdown, as summer approaches, the rise in temperature would play an important role in preventing the drastic spread of COVID-19 virus in India.

Several virologists hinted that by June this year, the impact of COVID-19 would be less than what it appeared in March-April.

The claims have fallen flat as the virus is mutating fast, becoming more potent than ever.

According to experts, the novel coronavirus is a new virus whose seasonality and response to hot humid weather was never fully understood.

"The theory was based on the fact that high temperatures can kill the virus as in sterilisation techniques used in healthcare. But these are controlled environment conditions. There are many other factors besides temperature, humidity which influence the transmission rate among humans," Dr Anu Gupta, Head, Microbiologist and Infection Control, Fortis Escorts Heart Institute, told IANS.

There is no built-up immunity to COVID-19 in humans.

"Also, asymptomatic people might be passing it to many others unknowingly. New viruses tend not to follow the seasonal trend in their first year," Gupta emphasized.

Globally, as several countries are now experiencing hot weather, the World Health Organization (WHO) reported a record hike in the number of coronavirus cases, with the total rising by 2,12,326 in 24 hours in the highest single-day increase since COVID-19 broke out.

So far over 11 million people worldwide have tested positive for the disease which has led to over 5,25,000 deaths, according to data from Johns Hopkins University. The US remained the worst-hit country with over 28 lakh cases, followed by Brazil with 15.8 lakh.

According to Sandeep Nayar, Senior Consultant and HOD, Respiratory Medicine, Allergy & Sleep Disorders, BLK Super Speciality Hospital in New Delhi, whether temperature plays a role in COVID-19 infection is highly debated.

One school of thought said in the tropical regions of South Asia, the virus might not thrive longer.

"On the other hand, another school of thought has found that novel Coronavirus can survive in a hot and humid environment and tropical climate does not make a difference to the virus. According to them, this is what distinguishes the novel coronavirus from other common viruses, which usually wane in hot weather," stressed Nayar.

Not much has been studied in the past and no definite treatment or vaccine is available to date.

"Every day, new properties and manifestation of the disease come up. As of now, the only way to prevent this monster is by taking appropriate precautions. Hand hygiene, social distancing, cough etiquette and face masks definitely reduce spread of COVID-19 infection," Nayar told IANS.

Not just top Indian health experts, even Indian-American scientists had this theory in mind that sunshine and summer may ebb the spread of the coronavirus.

Ravi Godse, Director of Discharge Planning, UPMC Shadyside Pennsylvania in the US told IANS in April: "In the summer, the humidity can go up as well, meaning more water drops in the air. If the air is saturated with water and somebody sneezes virus droplets into such air, it is likely that the droplets will fall to the ground quicker, making them less infectious. So the short answer is yes, summer/sunshine could be bettera.

According to Dr Puneet Khanna, Head of Respiratory Medicine and Pulmonology, Manipal Hospital, Delhi, COVID-19 death rates are not too different in tropical countries but since the disease affected them late it was yet to show its peak in these areas.

"The virus can survive well in hot and humid countries and this is proven now," he stressed.

Hubballi, Apr 23: Karnataka Chief Minister Siddaramaiah on Tuesday spoke to father of slain student Neha Hiremath over phone and said "sorry" over his daughter's killing, and assured that "we will be on your side".

The Chief Minister also informed Niranjan Hiremath, who is also a Congress councillor of Hubballi-Dharwad Municipal Corporation, about the government's decision to hand over the murder case to the Criminal Investigation Department (CID) and setting up a special court to fast-track trial.

"Niranjan... very sorry. We will be on your side," Siddaramaiah told Hiremath over the phone call during state's Law and Parliamentary Affairs Minister H K Patil's visit to Hiremath's house here.

In the conversation on Patil's phone with speakers on, Siddaramaiah can be heard informing Hiremath about the CID probe and setting up a special court.

"It is a serious offence... setting up a special court will ensure punishment for the accused person."

Hiremath thanked Siddaramaiah on behalf of his family well-wishers and the community for handing over the case to CID and setting up a special court "...ensure there is an order at the earliest and provide us justice," he said, as he also thanked Patil, Home Minister G Parameshwara, local Congress MLA Prasad Abbayya and others for their support.

Replying to this, Siddaramaiah said, "We will ensure it, at the earliest."

In a shocking incident, Neha Hiremath (23), was stabbed to death on the campus of BVB College last Thursday. The accused Fayaz Khondunaik, who fled from the scene, was arrested by the police subsequently.

Neha was a first year Master of Computer Application (MCA) student and Fayaz was earlier her classmate.

Siddaramaih on Monday had announced his government has decided to hand over the investigation into the incident to the Crime Investigation Department, and to set up a special court for speedy disposal of the case.

The case of brutal murder, which sparked widespread outrage, has snowballed into a political slugfest between ruling Congress and opposition BJP.

While the ruling party has tried to project it as an incident with personal angle, the saffron party has called it a "love jihad" case and has said it's a testimony of deterioration of law and order in the state.

Earlier, Siddarmaiah's statement that the murder was due to "personal reasons" and Home Minister G Parameshwara's comments that the duo was in love, has elicited sharp reactions from Hiremath and family members and opposition parties.

HSRP.jpg

With the Karnataka transport department extending the deadline for the installation of High Security Registration Plate (HSRP) twice--- in November last year and February, it is no longer planning to extend the same. The department ordered for the installation of HSRP before May 31.

The transport department through a notification in August last year, had mandated the installation on all the vehicles that were registered in the state prior to April 1, 2019. According to transport officials, there are nearly two crore vehicles that are supposed to get HSRP for their vehicles.

“As of now, the state has registered only 34 lakh HSRP installations, despite extending the deadline twice. From nearly 18 lakh installations since February, the numbers have almost doubled. However, there are still a large number of vehicles that have to opt for HSRP,” said C Mallikarjuna, Additional Commissioner for Transport (Enforcement).

“We will wait till May 31 to check for the total number of vehicles that fall in line. We are expecting HSRP installations to touch 75 lakh, after which we will consider an extension as the numbers indicate that people are falling in line and if some more time is given everyone will get it done. However, if we do not reach that number before the deadline, we will request the government not to extend the deadline but urge for an enforcement,” he said.

He also stated that a fine of Rs 500 will be imposed for the first time and if vehicle owners do not fall in line, it will be Rs 1,000 later until they have installed HSRP. “We will wait till the Model Code of Conduct ends and take the government’s opinion. We are going to request the government for strict enforcement if the HSRP installations are not satisfactory,” he added.

Bengaluru: The Congress and BJP will lock horns on the electoral battleground again, in less than a year, in Karnataka as the stage is set for voting in the first phase in 14 Lok Sabha seats on Friday.

It's going to be a straight fight between the ruling Congress and the BJP-JD(S) combine unlike the Assembly elections in May last year which witnessed a triangular contest among the three parties.

The state has a total of 28 Lok Sabha constituencies. The second phase of polling in the remaining 14 seats is on May seven.

A total of 247 candidates -- 226 men and 21 women -- are in the fray for the first phase in most of the southern and coastal districts.

More than 2.88 crore voters are eligible to exercise their franchise in 30,602 polling stations where polling will take place between 7 am to 6 pm.

While the Congress is contesting in all 14 seats, BJP has fielded nominees in 11 and its alliance partner JD(S), which joined the National Democratic Alliance (NDA) in three -- Hassan, Mandya and Kolar.

Besides the three, the segments where elections will be held on Friday are: Udupi-Chikmagalur, Dakshina Kannada, Chitradurga, Tumkur, Mysore, Chamarajanagar, Bangalore Rural, Bangalore North, Bangalore Central, Bangalore South and Chikkballapur.

In the 2019 Lok Sabha polls, Congress and JD(S), which were in alliance and ruling the state then, had secured just one seat each in these 14 segments. The BJP had won in 11 and ensured the victory of a party supported independent candidate in Mandya.

Having scored a thumping victory in the Assembly elections, the Congress now appears determined to put up a strong show.

Karnataka is the most important state for the BJP in south India as it's only here that it had held power in the past. 'Its alliance partner JD(S) is fighting to remain politically relevant, after the Assembly poll drubbing,' a political analyst said.

The Old Mysore region is the Vokkaliga heartland and parts of it have been the traditional bastion of the JDS.  However, the current elections are a battle for survival for JDS.

According to Karnataka Chief Electoral Officer Manoj Kumar Meena, 1.4 lakh polling officials will be on duty for the first phase.

Besides them, 5,000 micro-observers, 50,000 civil police personnel, 65 companies of Central Parliamentary Force and State Armed Police force of other States will also be deployed for security.

All the 2,829 polling stations of Bangalore Rural parliamentary constituency will be webcast, Meena said.

'This is as per the request of our returning officers and observers; so we have given more than double the Central parliamentary force for Bangalore Rural constituency. Seven companies of Central paramilitary forces have been inducted at the constituency since April 22,' he told reporters on Wednesday.

In fact, out of the total 30,602 polling stations in the first phase, 19,701 will be webcast, and 1,370 covered via CCTVs, he said.

Chikkaballapur has a maximum number of 29 candidates, followed by 24 in Bangalore Central, and Dakshina Kannada has the least number - nine.

JD(S) leader H D Kumaraswamy from Mandya, his brother-in-law and noted cardiologist C N Manjunath from Bangalore Rural on a BJP ticket, erstwhile Mysuru royal family scion Yaduveer Krishnadatta Chamaraja Wadiyar from Mysore, also from the BJP, and Deputy Chief Minister D K Shivakumar's brother and MP D K Suresh of Congress from Bangalore Rural, are among the prominent candidates in the fray in the first phase.

Also in the fray are BJP MP Tejasvi Surya from Bangalore South against Minister Ramalinga Reddy's daughter Sowmya Reddy of Congress, Union Minister Shobha Karandlaje on BJP ticket from Bangalore North against former IIM Bangalore professor M V Rajeev Gowda of Congress.

The Congress' performance in the elections, especially in the first phase which covers almost all Vokkaliga-dominated districts, is being seen as a big test of sorts for its state unit chief Shivakumar, who has made no secret of his ambition to become chief minister, amid speculations of change in guard mid-way of the Assembly term.

Stakes are also high for Chief Minister Siddaramaiah, as victory in particular in his home turf—Mysore and Chamarajanagar—is seen as key for strengthening hands, analysts say.

For the JD(S) and its state chief Kumaraswamy, the task is cut out -- to prove that the regional party is still a force to reckon with, particularly in the Vokkaliga dominated Old Mysuru or South Karnataka region.

Both Shivakumar and Kumaraswamy are Vokkaligas, and are engaged in a fierce turf war to consolidate their clout over the dominant community.

It is also seen as a kind of a 'litmus test' for state BJP president B Y Vijayendra, who has the onerous task of helping the party retain its supremacy in the Lok Sabha elections.

Ensuring a BJP sweep is paramount for the son of veteran leader B S Yediyurappa, to consolidate his position and silence critics who have questioned his selection for the post, overlooking seniors and seasoned hands.

The ruling Congress is mostly banking on the implementation of its populist five guarantee schemes. The BJP and JD(S) seem to be leveraging the 'Modi factor' to the hilt.
