Jun 1: Gold prices rose on Monday as riots in major U.S. cities rattled investors already reeling from strained Sino-U.S. relations and boosted demand for the safe-haven metal, with a weaker dollar lending further support.

"Concerns about the unrest in the United States at the moment appear to be weighing on market sentiment," said Michael McCarthy, chief strategist at CMC Markets, adding that rising tensions between the world's top two economies provided further support to gold.

Protesters have flooded the streets in the United States over the death of George Floyd in police custody, in a wave of outrage sweeping a politically and racially divided nation.

The closely packed crowds and demonstrators not wearing masks have sparked fears of a resurgence of COVID-19, which has killed more than 101,000 Americans.

Kozhikode, Apr 24: A four-month-old baby girl, who had tested positive for COVID-19 and suffering from congenital heart disease, died in a hospital here in Kerala early Friday after suffering a cardiac arrest, officials said.

This is the third COVID-19 death and the first infant fatality in the state where two elderly people had succumbed to the disease earlier.

The baby was admitted to the Medical College Hospital here on April 21 with history of fever, cough, breathing difficulties and seizure after being treated at two other hospitals and the end came at 6 am, a medical bulletin said.

State Health Minister K K Shailaja said doctors had made maximum efforts to save the life of the child, whose family belonged to Payyanad near Manjeri in Malappuram district.

"Preliminary information which we have is that there has been some primary contact", she told reporters in Thiruvananthapuram.

The protocol for COVID-19 cases would be followed for the baby's last rites, the Minister added.

As of Thursday, the total active COVID-19 cases in the state stood at 129.

The bulletin said on arrival at the hospital on Tuesday the baby was in shock and had respiratory failure.

"She was resuscitated, mechanically ventilated and appropriate antibiotics for pneumonia and supportive measures to correct shock were started", it said adding the baby, however, continued to remain sick.

"Even though there was no history of any high or low risk contact or any epidemiological links as the child comes from SARI (Sever Acute Respiratory infection) criteria, she was admitted to the COVID-ICU and swab was taken and she tested positive", the bulletin said.

Contact tracing of those who had come in contact with the child was in progress.

Mallapuram District Medical Officer (Health) Dr Sakeena K said the child was having severe health issues from its birth itself and was admitted to a private hospital in Manjeri near here with breathing problem.

New Delhi, Apr 5: Joining efforts to fight COVID-19, the Defence Research and Development Organisation (DRDO) has designed a full-body disinfection chamber and a special face protection mask for healthcare professionals, officials said.

The special chamber called 'PSE' has been designed by Vehicle Research Development Establishment (VRDE), Ahmednagar, a DRDO Laboratory.

The walk through enclosure is designed for personnel decontamination, one person at a time. It is a portable system equipped with sanitiser and soap dispenser, officials said.

The decontamination is started using a foot pedal at the entry. On entering the chamber, electrically-operated pump creates a disinfectant mist of hypo sodium chloride for disinfecting, the DRDO said in a statement.

The mist spray is calibrated for an operation of 25 seconds and stops automatically indicating completion of operation. As per procedure, personnel undergoing disinfection will need to keep their eyes closed while inside the chamber, it said.

The system consists of roof mounted and bottom tanks with a total of 700 litres capacity. Approximately 650 personnel can pass through the chamber for disinfection until the refill is required, the DRDO said.

The system has see-through glass panels on side walls for monitoring purpose and is fitted with lights for illumination during night-time operations, it added.

This system can be used for disinfection of personnel at the areas of controlled ingress and egress such as entry and exit to hospitals, malls, office buildings and critical installations, officials said.

Also, Research Centre Imarat (RCI), Hyderabad, and Terminal Ballistics Research Laboratory (TBRL), Chandigarh, have developed face protection mask for healthcare professionals handling COVID-19 patients, the DRDO added.

Its light weight construction makes it convenient for comfortable wear for long duration. This design uses commonly available A4 size Over-Head Projection (OHP) film for face protection, it said.

One thousand face shields are being produced daily in TBRL and provided to Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, it said.

Similarly, 100 are produced at RCI and these have been handed over to Employees' State Insurance Corporation (ESIC), Hyderabad. A demand of 10,000 shields has been received from PGIMER and ESIC hospitals based on successful user trials, the DRDO added.
