The spread of infection is fairly rapid and global.
World Health Organization (WHO) has warned of a possible surge in Covid-19 patients in the coming days. WHO predicts that corona virus infection worldwide will exceed one million.WHO Director General, Dr. Tedros Adhanom Ghebreyesus, highlighted the number of deaths doubled last week. WHO says it is concerned about ‘almost exponential’ growth in the number of confirmed cases in the 180 affected countries. A total of 937,783 people have been infected with the virus, with more than 47,273 deaths.
As we enter the fourth month since the start of the pandemic, I am very concerned about the rapid increase and spread of global infections,” said Ghebreyesus, quoted.Thursday, April 2, 2020.”The number of deaths has more than doubled in the past week. In the next few days we will reach one million confirmed Covid-19 cases and 50,000 deaths,” he said.Ghebreyesus said, there are 74 countries now joining the WHO Solidarity Trial. The program seeks to compare four drugs and combination drugs to ‘fight’ the virus.
More than 200 patients have randomly undergone trials in an effort to find a vaccine. Ghebreyesus said, WHO is currently prioritizing frontline health workers to be able to access personal protective equipment (PPE), including medical masks and respirators.

Muslim scientists find the shortest Covid-19 Quick Test, only 5 minutes!
Singapore became the first Asian country to claim to have succeeded in creating a Coona-19 corona virus rapid test kit. The device was found by a Muslim woman named Professor Jackie Ying, who heads the NanoBio Lab at the Agency for Science, Technology and Research (A * Star).Jackie and his team claimed to have found the Covid-19 rapid test kit, the results of which could be known in just five minutes. If this tool has received approval from the authorities, the corona disease checker will be the fastest Covid-19 test kit in the world.They hope to submit the test kit to get approval within one month.

How Corona Detectors Work
This test tool works by copying viral genetic material in a patient’s secretions that is collected through a swab or mucous sampling from the throat.Patient secretion samples are then inserted into the test kits created by Professor Ying and his team. With very fast amplification which is claimed to move quickly, the test kit then gives results between five to ten minutes.Professor Ying said.

Not Just Fast Also Clai ed Accurate
Once approved, the technology can be used to make similar kits for use in hospitals. This tool will also be adapted for use in general practitioner clinics, added Prof. Ying.Professor Ying and his team are among Singapore researchers and around the world competing to create test kits that can tell if someone is getting Covid-19 quickly. This tool is usually much faster than standard laboratory tests today.The challenge, said Prof. Ying, is to develop quick and accurate diagnostics that can be done without using expensive machines.

Rapid Tests Are Important in the Middle of a Pandemic
In the midst of an increasing pandemic globally, finding rapid test kits is a top priority for preventing the widespread spread of the virus. Because if you lack a rapid test kit, the number of people who are potentially positive at Covid-19 will not be known forever.Moreover, the World Health Organization (WHO) has always stressed the importance of rapid tests that allow Covid-19 cases to be handled early to be isolated immediately, before spreading to more people.
Before this standard laboratory tests were used to determine whether someone was positive of Covid-19 or not. You do this by finding the genetic material of the virus in the patient’s secretions after being taken using a swab.

Standard LabJTests Take a Long Time
Testing requires at least two to three hours using a special machine to get results. If the sample needs to be sent to a central laboratory, the completion time is even longer.This standard laboratory test works by first converting the corona virus RNA into DNA in a method known as reverse transcription (RT).
Then, the polymerase chain reaction (PCR) technique is used to strengthen the genetic material of the virus so that it can be easily detected. This is called the RT-PCR test.”This is basically a molecular photocopier. PCR was discovered in 1984, and even in this method, around 60 percent of the time is spent waiting for the PCR machine to heat up and then cool down,” said Prof Ying.

Much simpler and faster
While his latest discovery and his PhD student, Muhammad Nadjad Abdul Rahim, is a new method for amplifying specific DNA / RNA at a single temperature.Just like PCR, their method can ‘copy’ viral genetic material millions of times. The difference in their new method is that they can produce up to millions of copies in one minute.Another difference is that unlike PCR, the approach of scientists at A * Star does not require heating and cooling between each controlled amplification step. Amplification is activated by special enzymes developed in Prof. Ying’s laboratory.
Prof Ying said he and his team of scientists had been working tirelessly for about six weeks to create a rapid test kit, after A * Star chief executive Frederick Chew gave them the challenge of making a quick test for Covid-19.
