Latest Ebola News: Siddhartha Mukherjee urges scientists to be ingenious and beat the Ebola virus

Describing Ebola as an ingenious virus, Pulitzer Prize winning Indian-American author and cancer physician Siddhartha Mukherjee has said ‘we need to be just as ingenious’ to fight the disease by detecting viruses in the pre-symptomatic phase of an infection. In an op-ed in the New York Times on Sunday, Mukherjee said in the wake of the case of Thomas Duncan, the Dallas man who contracted the virus and died, three strategies to contain the entry and spread of the virus in the US have been proposed.

The first suggests drastic restrictions on travel from Ebola-affected nations, the second involves screening travellers from Ebola-affected areas while the third proposal is of isolation of all suspected patients and monitoring or quarantining of everyone who came into contact with them. ‘Ebola is an ingenious virus,’ Mukherjee wrote in the op-ed, adding, ‘To fight it, we need to be just as ingenious.’ (Read: 5 reasons the ebola virus should never come to India) Also Read - Ebola death toll rises to 55 in DR Congo

Mukherjee, who won the Pulitzer in 2011 for his book ‘The Emperor of All Maladies: A Biography of Cancer’, suggested a fourth strategy involving use of novel methods to detect viruses in the pre-symptomatic phase of an infection. ‘One of these involves the polymerase chain reaction, or PCR, a chemical reaction that amplifies pieces of a virus’s genes floating in blood by more than a millionfold, which is what makes early, pre-symptomatic infections identifiable,’ Mukherjee said.

He said as an oncologist working with blood cancers, he has been using variants of the technique to detect sub-clinical infections in patients for nearly a decade. He cited a 2000 study in leading medical journal The Lancet, according to which 24 ‘asymptomatic’ individuals exposed to Ebola were tested using PCR. The test now requires only a teaspoon of blood and the sample is transported, on ice, to a centralised lab with results back in a few hours. (Read: How the Ebola virus spreads in humans)

‘Technologies like this allow us to imagine a new form of quarantine. Rather than relying on primitive instruments, indiscriminate profiling or questionnaires, we should consider running a pilot program to test asymptomatic travellers using sensitive PCR-based techniques,’ Mukherjee said. The assistant professor of medicine at Columbia University said huge logistical questions would need to be solved, including where would such a screening test be administered, what infection precautions would need to be in place for such testing and who exactly would be tested.

‘Despite these questions, we should develop a pilot program, perhaps targeting the worst-hit regions of the epidemic. It certainly does not solve the civil liberties questions of quarantining, but it makes them vastly more palatable,’ he said. (Read: Ebola Facts: Top 7 myths busted)

Here are 8 tips to prevent Ebola infection

Educate yourself about Ebola: Knowing the symptoms, modes of transmission and preventive measures is the first step to prevent the spread of the disease. This information is especially important for those who are travelling to and from affected areas in West Africa.

Maintain sanitary conditions: Basic hygiene plays a very important role in preventing Ebola. The exact way by which the virus enters the body is still debatable but skin and eyes are suggested routes for viral entry. However, food and water may also serve as source of entry. So, simple acts like washing hands before eating and disinfecting surfaces and covering the mouth can help prevent the spread of the virus, especially in areas surrounding the areas of outbreak.

Avoid contact with blood and body fluids: Ebola virus spreads through all body fluids including blood, semen, saliva, sweat, urine, fecal matter and vomit of infected individuals. Healthcare workers and medical staff who are more likely to come in contact with infected body fluids, infected needles and first aid, should handle them with protective gear.
