Potholes on roads? Inform these officials and complain to representatives

Bengaluru, Apr 8: Karnataka government has decided to postpone its first mass marriage ('Saptapadi') scheduled for April 26 due to lockdown in force, Minister for Muzrai, Port and Fisheries Kota Srinivas Poojary said here on Tuesday.

Talking to media here, he said that the first phase is likely to be clubbed with the second phase to be held on May 24. However, it all depends upon the situation prevailing at that time.

The state government had proposed to conduct the mass marriage scheme at select Muzrai temples in two phases on April 26 and May 24. Around 2000 applications with due documents were received for mass marriage from those who wished to tie the nuptial knot.

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.

Bengaluru, Jul 19: Three legislators of the opposition Congress in Karnataka, including 2 MLAs and 1 MLC tested positive for coronavirus and are under treatment, a party official said on Saturday.

"Our Bailhongal MLA Mahantesh Koujalgi in Belagavi district and Humnabad MLA Rajashekhar Patil and his MLC brother Chandrashekhar Patil in Bidar district tested positive for the infection and are under treatment at designated hospitals," party spokesman Ravi Gowda told media persons in Bangaluru.

Koujalgi's swab sample was taken on Friday after he showed signs of illness and its result turned positive earlier in the day.

"As Koujalgi attended a review meeting at Bailhongal, about 20 officials who participated in the meeting have been home quarantined," said Gowda.

Koujalgi is the second lawmaker in the state's northwest region to test positive after BJP's Belagavi North assembly segment MLA Anik Benake tested positive for the virus on July 15.

"Patil brothers were in self quarantine after meeting BJP's Bidar Lok Sabha member Bhagwanth Khuba, who tested positive on Wednesday. Their tests also showed they were infected with the virus," Gowda said.

Congress MLC Sandesh Nagaraj, who tested positive on Friday, is under treatment at a private hospital in Mysuru.

Dakshina Kannada district Youth Congress president Mithun Rai is in institutional quarantine in Bengaluru after he tested positive for the infection.
