Dr Ravikanthe Gowda assumes charge as DK SP, vows to curb criminal, communal elements

Thiruvananthapuram, Apr 20: The Kerala government announced the relaxation of COVID-19 lockdown restrictions in two zones, allowing among other private vehicles movement in an odd-even basis and dine-in services at hotels from Monday.

State police chief Loknath Behera said the relaxations of restrictions imposed would come into effect in the Green and Orange-B zones in the state from Monday,an official release said.

Earlier, the Left government had colour-coded 14 districts of the state into four zones-- Red, Green, Orange-A and Orange-B, for containing the Covid-19 pandemic. Red zone comprises Kasaragod, Kannur, Kozhikode and Malappuram districts. In this zone, a complete lockdown will be in place until May 3 while two entry and exit points are allowed for carrying essential commodities to coronavirus hotspots. Orange-A zone comprises Pathanamthitta, Ernakulam and Kollam while orange-B zone comprises Alappuzha, Thiruvananthapuram, Palakkad, Thrissur and Wayanad.

The lockdown will be in effect until April 24 in this zone and then partial relaxation will be allowed. Kottayam and Idukki come under the Green zone, in which lockdown will be in effect until April 20 and then regulations will be eased. However, large gatherings, the functioning of educational institutions, religious functions, celebrations and travel outside the district will not be allowed in this zone.

Not more than 20 people are allowed to take part in weddings and funerals, according to government instructions. On the functioning of courts, the release said, "Courts in the Green and Orange-B zones will re-open on April 21 while that in Orange-A zone will start functioning from April 25. The courts will function with 33 per cent of staff. The cases will be heard via video conferencing."

Meanwhile, the Bankers' Council has announced that banks will function as per the usual timings from Monday in the state except four districts falling under the Red zone. The Transport Ministry has clarifiedthat public transport won't be allowed to ply in the state during the lockdown period. "Inter-district travel will not be allowed despite relaxations in the state, but essential services such as medical services, food supplies will not be stopped. However, in case of emergency, inter-district travel will be allowed with an affidavit prepared by the traveller," Behra said in a release.

On the implementation of the odd-even scheme for private vehicles, the police said, "Vehicles with odd numbers will be permitted on Mondays, Wednesdays and Fridays. Those with even numbers will be allowed on Tuesdays, Thursdays and Saturdays." Woman drivers travelling solo or with dependants are also exempted from it, police said. On Sundays, only those working for essential services are allowed to use their vehicles.

All education institutions, cinema halls, shopping malls, public parks, bars, places of worship will remain closed in all zones of the state. The health department and local administration, which carry out sanitation work before the monsoon, are allowed to operate. Four-wheelers are permitted to carry two passengers besides the driver and in case of a two-wheeler, only the driver will be allowed while the pillion rider is allowed in case the person is a family member.

On Dine-in services, a government order said it is allowed at hotels and restaurants until 7 PM in Green and Orange-B zone from Monday and in Orange-A zone from April 24. However, take-away counters can function until 8 PM, it said. Kerala on Sunday reported two positive cases of Covid-19 in the state taking the total number of affected to 401 while the health department announced that 13 people were cured.

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Bengaluru, May 11: Karnataka Chief Minister BS Yediyurappa on Monday inaugurated four buses that have been converted into COVID-19 testing facilities in Bengaluru.

State Deputy Chief Minister C N Ashwath Narayan, Karnataka Revenue Minister R Ashoka and Member of Parliament from Bengaluru South Tejasvi Surya were also present.

"The mobile fever clinic bus initiative was taken by Sanchit Gaurav, Founder and CEO of Housejoy, in association with the Government of Karnataka, the Karnataka State Road Transport Corporation (KSRTC), MP Tejaswi Surya, other partners, to increase the number of COVID tests across Bengaluru and win the fight against the virus," said KSRTC in a statement.

The bus is divided into two zones with beds and a consultation area, maintaining proper hygiene conditions.

The KSRTC said there will be four teams with four mobile bus clinics across Bengaluru - each team comprising of one doctor, three nurses and one lab technician with several volunteers facilitating the process.

The teams will be starting from red zones and will try to screen the maximum number of residents from these zones for symptoms and quarantine those who test positive.

"The testing process will start by providing free glucose, blood pressure test and COVID-19 symptoms consultation for all residents," KSRTC added.

If anyone showcases any COVID-19 symptoms, their swab will be collected immediately for testing by Biognosys Technologies (ICMR certified).

Further, the information will be provided to the government and place the person under quarantine.

"KSRTC has already initiated this mobile fever clinic buses with the association of the District Administration in Mysuru, Mandya, Tumkur, Mangaluru, Bagalkote, Hubli, Belagavi, Bengaluru and Raichur," it said.

According to the KSRTC on April 25, the cost of this clinic construction on a bus is Rs 50,000.
