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, Jun 26: Karnataka recorded 445 new Covid cases, majority of whom were contacts of earlier positive cases, breaching the 11,000 mark to settle at 11,005, an official said on Friday.

"New cases reported from Thursday 5 p.m. to Friday 5 p.m., 445," said a health official on Friday.

In the past 24 hours, 10 patients succumbed to the virus in Karnataka, three in Bengaluru Urban and one each in Kolar, Dharwad, Shivamogga, Bagalkote, Bidar, Kalaburagi and Ballari.

Like everyday, contacts of earlier cases outnumbered domestic returnees in the number of infections, constituting 39 per cent.

Positive cases with domestic travel history numbered 65, a mere 15 per cent and majority to Maharashtra.

There were also 21 cases with international travel history to countries like Oman, Qatar, Saudi Arabia and Dubai.

On Friday, cases spiked in Bengaluru Urban, Ballari, Kalaburagi, Koppal, Dakshina Kannada, Dharwad, Raichur, Gadag, Chamarajanagar, Udupi, Yadgir, Mandya, Uttara Kannada, Bagalkote, Shivamogga, Kolar and Mysuru.

Among the new cases, Bengaluru Urban accounted for 144, followed by Ballari (47), Kalaburagi (42), Koppal (36), Dakshina Kannada (33), Dharwad (30), Raichur (14), Gadag (12), Chamarajanagar (11), Udupi (9), Yadgir (7), Mandya, Uttara Kannada, Bagalkote, Shivamogga and Kolar (6 each).

Mysuru (5), Chikkamagaluru and Kodagu (4 each), Hassan and Bengaluru Rural (3 each), Vijayapura, Tumkur and Haveri (2 each) and Bidar, Belagavi, Davangere, Ramanagara and Chitradurga (1 each).

As many 144 patients are suffering from Influenza-like Illness (ILI) and 19 from Severe Acute Respiratory Infection (SARI).

In all, 5.68 lakh samples have been tested so far, of which 5.41 lakh tested negative.

Meanwhile, 178 patients are admitted in the ICU.

Of the total 180 deaths, Bengaluru Urban has accounted for 81, followed by Bidar (16), Kalaburagi (15), Ballari (9) and Dakshina Kannada (8), among others.

Bengaluru, Jul 11: Amidst the mounting number of covid-19 cases, Karnataka is witnessing another disturbing trend of increasing number of people ending their life. After the lockdown was relaxed, the state saw a worrying jump in the number of suicides.

According to statistics, as many as 2,211 suicide cases have been registered in just two months. The number of suicides rose by 23% in May to 1,127, and by another 18% in June to 1,084, from an average of 912 suicides in the first three months of the year. 

In April, however, the number nearly halved to 477. But April was also the month during which the lockdown (announced on March 24) was complete, and everyone was at home -- which, experts say, could have prevented people with suicidal tendencies from taking their own lives.

Shockingly, number of teenagers including school children committing suicide also increased in the state in past couple of months.

With the pandemic still accelerating and impacting people in multiple ways, the World Health Organisation has urged people to pay greater attention to mental health and suicide prevention. 

Dr Poonam Khetrapal Singh, Regional Director, World Health Organisation (WHO), South-East Asia Region, said stigma related to Covid-19 infection may lead to feelings of isolation and depression. Another precipitating factor impacting mental health amidst Covid-19 could be domestic violence, which is reported to have increased globally as several countries imposed lockdowns, she said.

“Hitting lives and livelihoods, the pandemic is causing fear, anxiety, depression and stress among people. Social distancing, isolation and coping with perpetually evolving and changing information about the virus has both triggered and aggravated existing and pre-existing mental health conditions, which need urgent attention,” she said.

Dr H Chandrashekar, professor and head of the department of psychiatry at Victoria Hospital, said reasons for suicide are always multi-factored, combined, cumulative, unresolving and interrelated.

“There is grief everywhere now due to deaths related to Covid-19, and it may have an adverse effect on some. But people should be watchful of their family members, especially those who are in depression and have a history of suicide attempts. One should never ignore signs, like when someone says they feel like ending their life. They should not be left alone, and unconditional support needs to be given. Also, objects that could be used to commit suicide must be kept away from them,” Dr Chandrashekar said.
