Temple fire: One booked for violating licence norms

Thiruvananthapuram, Jun 15: Kerala Chief Minister Pinarayi Vijayan''s daughter Veena married top DYFI All India president Mohammed Riaz at the chief minister''s official residence in the presence of selected guests.

Riaz and Veena became husband and wife at a solemn function held under Covid protocols with not more than 50 people present.

This was the second marriage for both, as their first ones ended in divorce.

Riaz has two children, while Veena has a son from their respective previous marriages.

Riaz is a lawyer by profession and had contested the Kozhikode Lok Sabha seat in 2009 but lost to the Congress'' M.K.Raghavan.

Veena runs her own software company in Bengaluru.

While the marriage has already been registered recently, the wedding event was a closed door affair, with just very close relatives of the couple besides a few senior party colleagues of Vijayan.

Mangaluru, June 27: The district health authorities are likely to conduct mass random testing for Covid-19 in Ullal town on the outskirts of the city in the wake of detection of several new coronavirus positive cases there in past couple few days.  

An elderly woman from Azad Nagar in Ullal was died of coronavirus earlier this week. Many others including a couple of policemen also tested positive for the deadly virus in vicinity.

Following this, local elected representatives including MLA U T Khader and religious leaders of Ullal held a meeting regarding taking steps to control the spread of the virus. In the meeting Mr Khader suggested the authorities to conduct random testing in Ullal town. 

Apart from Azad Nagar, covid-19 cases have surfaced in Kodi, Bangera Lane and in the surroundings of police station and Sahara Hospital triggering panic among people. Hence, the authorities are like to conduct random testing of auto rickshaw drivers, fishermen, street vendors among others. 

Meanwhile, several mosques in Ullal have reportedly decided to suspend congregational prayers temporarily.

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
