Deaths of children: Careless Yogi should step down as CM, says U T Khader

San Diego, Apr 15: Several people lost their sense of smell or taste weeks ago globally and are still waiting for it to come back and now, researchers have identified an association between sensory loss and novel coronavirus 2019 (COVID-19) infection, indicating that loss of smell and taste may be considered as early symptoms of the deadly disease.

Interestingly, the study also found that persons who reported experiencing a sore throat more often tested negative for COVID-19.

The team from University of California-San Diego found high prevalence and unique presentation of certain sensory impairments in patients positive with COVID-19.

Of those who reported a loss of smell and taste, the loss was typically profound, not mild.

"Based on our study, if you have smell and taste loss, you are more than 10 times more likely to have COVID-19 infection than other causes of infection. The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell and taste follow as other very common initial symptoms," explained study researcher Carol Yan from UC San Diego.

"We know COVID-19 is an extremely contagious virus. This study supports the need to be aware of smell and taste loss as early signs of COVID-19," Yan added.

For the findings, published in the journal International Forum of Allergy and Rhinology, the research team surveyed 1,480 patients with flu-like symptoms and concerns regarding potential COVID-19 infection who underwent testing at UC San Diego Health from March 3 through March 29, 2020.

Within that total, 102 patients tested positive for the virus and 1,378 tested negatives. The study included responses from 59 COVID-19-positive patients and 203 COVID-19-negative patients.

Encouragingly, the rate of recovery of smell and taste was high and occurred usually within two to four weeks of infection.

"Our study not only showed that the high incidence of smell and taste is specific to COVID-19 infection but we fortunately also found that for the majority of people sensory recovery was generally rapid," said Yan.

"Among the COVID-19 patients with smell loss, more than 70 per cent had reported improvement of smell at the time of the survey and of those who hadn't reported improvement, many had only been diagnosed recently," she added.

Sensory return typically matched the timing of disease recovery.

In an effort to decrease the risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus.

"It is our hope that with these findings other institutions will follow suit and not only list smell and taste loss as a symptom of COVID-19, but use it as a screening measure for the virus across the world," Yan said.

The unexpected lockdown to prevent spread of covid–19 has caused a serious damage to the lives of Indian expatriates irrespective of laborers and entrepreneurs in Kingdom of Saudi Arabia. Different stories of expatriates' ordeals are emerging from the region. 

Abdul Razaq, hailing from Udupi in Karnataka has been running small scale business at Jeddah, Saudi Arabia, based on oil refinery projects of the government. He was undergoing medical treatment for his cancer which is in fist stage. He explaines his ordeals caused by lockdown and stopping the flight facility. 

“I was regularly visiting home country for the treatment of cancer. Now I cannot go as international flight service has been stopped. I expect that government will hear problems of expatriates and will arrange facilities to take us back to home”, he said.

Mubeen from Bengaluru was working on temporary basis  for a company in Jubail. He had lost his jobs like some of his colleagues due to the lockdown.

“As everything was alright, I had brought my parents recently to Saudi Arabia on a visit visa. Things changed drastically with covid-19 attack. Continuous lockdown caused burden over the company and they removed temporary employees like me to control possible losses” he said.

“Now owner of the flat has been harassing me for the rent. I do not have money either to pay rent or to cover daily family expenses. I do not know what to do further”, he added. 

Iqbal from Mangaluru left for Saudi Arabia to help his family. He got a job in a juce centre in Dammam recently. Corona lockdown made his life difficult. He is eager to return his home country. 

“I came to Saudi Arbia because of financial difficulties as I had not found any job with good salary there. I thought I can earn well by going to Saudi Arabia. However, here too the salary was not so good. Now juice center is closed due to lockdown and sponsor is giving very small amount of money as salary through which we cannot afford our expenses and our families back in home,” he said.

“Here It is not easy get help of fellow Indians since most of them have their own ordeals. I would like to return home country; there however we can manage to get help of friends and relatives. I am looking forward the help of Indian government to start air facility for stranded NRIs,” he said. 

Mohsin from Mysuru is a taxi driver in Dammam, Saudi Arabia. He was earning on commission basis. Now Saudi government banned movement of taxis in the region, which pushed him and his fellow taxi drivers into trouble.

“We were earning commissions daily on the basis of trips. Now we cannot move outside with taxi since it may cause us to pay the fine of SR.10000. How can I manage my expenses and family members in home?”, he asked.

There are cases of pregnant women who have to return India for delivery. Those who brought family here on visit visa will not have insurance. Delivery charges and any kind of medical facilities without insurance in Saudi Arabia is very expensive. Expatriate Indians with such problems are awaiting government's help.

“I had brought my wife on one year visit visa. Now she is pregnant and I have to send her back to home for delivery. If lockdown continues, it is difficult to send back and we have to spend big amounts for delivery without insurance. It is a big burden to me as I work for small salary in a company”, said Yunus from Hyderabad, who is living in Jeddah, Saudi Arabia.

Lockdown is haunting even entrepreneurs in Saudi Arabia. Most of expatriates in the industrial hub of Jubail are doing business based on Saudi Government’s oil refinery projects. Saudi Arabia temporarily stopped most of the projects as part of public health safety measures to maintain social distance. 

“We are doing business based on oil refinery projects. Now projects are stopped. We brought around 1100 people on work permit visa on temporary basis. And also, we have around 1200 permanent workers. It is a big burden to provide them with food, accommodation and salary. It may cause a big loss for our company”, said owner of expatriates company, Sheikh Mohammed.

Saudi Arabia had reported first corona virus affected case in March 2, 2020. At the end of March, it was 1600 and now it already corssed 6000. Saudi Health ministry has cautioned the number of affected people may rise 10000 to 200,000 and directed for more precautionary measures. In such case, the Indian expatriates may have to face crisis in the region. 

Indian expatriate organizations are demanding for immediate intervention of Indian government to ensure better quarantine facility and treatment of NRIs in Saudi Arabia as the cases are increasing rapidly. The condition of laborers in some of the camps are such that seven to eight people should share a single bed room. 

“Normally if there is a flat, it will consist three to four bed rooms. In single bedroom companies will provide three four bunk beds and six to eight people should share the room. In such cases, if a person affected with virus it will spread quickly to others. Thus, Indian government should ensure quarantine facility for NRIs”, says Wasim Rabbani, president of Indian Social Forum, Eastern Region, Saudi Arabia. 

President of Karnataka Non Residential Indians, A forum for the NRI organizations of Karnataka, Zakaria Muzain says Indian Government should immediately interfere to bring back those stranded NRIs who wish to return home. Government should intervene to pressure Indian embassy to take the issues of troubled expatriates. 

“Government should make special flight arrangement for such NRIs in trouble. It should also arrange quarantine facility for those who return to India. Already there are many Non-Governmental charity organization which have come forward to give their facilities for NRIs”, he said. 

NRIs from all categories are looking forward for the help of Indian government. It is important to Indian government to take quick action as the problem is increasing in Saudi Arabia.
