Congress supporting SDPI to gain minority votes, says Pramod Muthalik

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.

Mangaluru, Jun 1: A youth was hacked to death and two others suffered critical injuries following a fight between two gangs at Yekkaru Devaragudde near Kateel under the limits of Bajpe police station last night.

The deceased has been identified as Keertan (20), a resident of Marakada. The injured are Nitin (20) and Manesh (20). It is learnt that old animosity led to the attack and murder.

According to sources, members of both gangs were friends in the past. They had become enemies of each other following a fight regarding sand mining.

Sources said that Keertan, Nitin, and Manesh had reportedly invited their rival gang to Devaragudde for some discussion. A verbal friction arose between the two gangs and it culminated in the attack by the rival gang members with daggers. Keertan reportedly died on the sport. The other two were taken to hospital.

The accused fled the scene soon after committing the crime. A case has been registered at Bajpe police station. A manhunt has been launched to nab the accused.

New Delhi, Apr 12: Ramping up efforts to "stamp out" coronavirus cases in the state, Kerala Finance Minister Thomas Isaac has said that not only lockdown but intense testing of people and tracing of their contacts are also equally important in the fight against the outbreak.

Kerala, which was the first state in the country to report a coronavirus infection in late January, has also prepared a time table for coming out of the lockdown and there would be district-specific strategies to tackle the situation while the number of cases are on the decline.

In efforts to curb spreading of coronavirus infections, the country is under a 21-day lockdown till April 14 and many states have sought an extension amid rising number of cases. Kerala has proposed extending the lockdown and gradual phasing out after proper assessment.

"Lockdown should go on till we stamp out entire infections. Now, it is not enough to have lockdown. Equally important is that we should have intense testing, tracing and isolating (of people with coronavirus infections)," he said in a telephonic interview.

The government is closely monitoring the situation and there would be region-specific or district-specific strategies in place to tackle the outbreak, he said.

Against the backdrop of the lockdown that has also disrupted economic activities, Isaac said an exit strategy is being prepared and restrictions are being relaxed in certain segments, including agriculture.

Coronavirus India update: State-wise total number of confirmed cases, deaths on April 12

"The number of patients is coming down (in the state). We hope that in the coming days, the decline will be much more faster," he said during the interview late Friday.

On Saturday, the Kerala government said there were a total of 373 confirmed cases of coronavirus infections and 228 patients were under treatment in various hospitals in the state.

Keeping the trend in the last few days, the number of people under observation has come down to 1,23,490. So far, 14,613 samples from people with symptoms were sent for testing and the results of 12,818 samples have come negative, the government said in a statement on Saturday.

Indicating that there would be a calibrated exit from the lockdown, Isaac said the withdrawal would depend on three main factors, including the count of cases and the percentage of people who are under observation.

While emphasising that people must also be fed during the lockdown period, Isaac also said a time table is being prepared by the state to come out of the lockdown.

Even as strict measures are being implemented to deal with the current situation, the state is also preparing for a possible third wave of coronavirus cases.

Three students, who had returned from the Chinese city of Wuhan, were tested positive. They were also the first such cases, to be reported in January-February period, and have recovered. Wuhan was the epicentre of coronavirus infections before it spread to other countries.

Later, there was a second wave of infections in Kerala.

According to the minister, the possibility of a third wave has also been considered for the exit strategy.

"A lot of Malayalees are expected to come back from outside the state. We will welcome them... before that, we want to stamp out all Covid cases in Kerala. Flatten the curve completely so that when these people from outside, they will be quarantined, they will be tested and only then they will be able to integrate with the rest of the community," he said.

The Kerala government's measures, including extensive testing and efforts to trace people who came in contact with coronavirus-infected persons, have helped in curbing spreading of infections.

The state's public healthcare system has also been appreciated in various quarters.

"People are health conscious. There is a demand for quality healthcare services and the response to this demand has been strengthening of the public healthcare system. We have a robust public healthcare system," the minister emphasised.

On April 9, Isaac tweeted about low level of coronavirus spreading in the state.

"International norm for Covid spread is 2.6 per 1 Covid patient. Total number of primary Covid infected who arrived in Kerala from abroad is 254. The secondary spread has been limited to 91. The international mortality rate is 5.75. With just 2 deaths, rate in Kerala is 0.58," he had tweeted.

Death toll due to the coronavirus increased to 273 and the number of cases to 8,356 in the country on Sunday.
