The deadly swine flu virus has become even more lethal in India as it has mutated, a report by two Indian- American researchers at MIT’s Department of Biological Engineering has shown.
Contradicting reports from Indian health officials claiming that the H1N1 virus has not changed since it emerged in 2009, the MIT report says that the virus has undergone two crucial mutations in the hemagglutinin protein that are known to make the virus more virulent.
The researchers said that very little scientific data is available on the virus, and stressed on the need for better surveillance to track the outbreak and to help scientists to determine how to respond to this influenza variant.
‘We need to understand the pathology and the severity, rather than simply relying on anecdotal information.’ Ram Sasisekharan, one of the researchers said.
The virus killed more than 18,000 people worldwide between 2009 and 2012.
The research was funded by the National Institutes of Health, the National Research Foundation through the Singapore-MIT Alliance for Research and Technology, and the Skolkovo Foundation.
Swine flu is a disease that attacks the respiratory tract of pigs, is caused by influenza viruses
The first time when Swine Flu was identified in humans was in the year 2009 in Mexico
Consult your doctor if you think you are at a higher risk of acquiring this infection
New Delhi (India), Aug 22, 2017: Swine Flu can get transferred from one person to another. Thus, it creates a panic situation whenever a single person is infected with this disease. To avoid catching this disease we can take some precautions.
As per the data from the Ministry of Health and Family Welfare India- there has been 8,648 Swine Flu cases and 345 deaths caused by this disease till May 7, 2017. There were 1,786 Swine Flu cases and 265 deaths caused by it in 2016. Till May 7, Tamil Nadu alone has had 2,798 cases of it, 181 and 130 people suffered at the hands of this disease in Maharashtra and Gujarat respectively. The worst years for Swine Flu outbreak in India were 2009-10 when it affected almost 50,000 people and took more than 2,700 lives across the country.
According to ANI report, some important guidelines on diagnosis of Swine Flu are given below. We have also mentioned the steps one should take if they catch Swine Flu and other crucial pointers which you don’t want to miss.
What is Swine Flu?
Swine flu is a disease that attacks the respiratory tract of pigs, is caused by influenza viruses. The symptoms shown by an infected animal are barking cough, decreased appetite, listless behavior and nasal secretions. The virus can mutate and get easily transmissible in humans.
The first time when Swine Flu was identified in humans was in the year 2009 in Mexico. After a few months, the very first of the swine flu cases were reported; slowly the rate, at which H1N1-related illness started spreading, was increasing around the globe. As a result, in August 2010 the World Health Organization (WHO) declared the infection ‘a global pandemic’ (a disease prevalent all over the world).
Even now, H1N1 has not stopped spreading is still getting circulated in humans, as a ‘seasonal flu virus’ and protection against this strain was thus included in seasonal flu vaccines. More recently, another strain, H3N2 infected humans in 2011.
What is the time period till this disease lasts?
Generally, the incubation period of a swine flu virus is between 3 to 7 days but if one catches a serious infection it can last about 9 or even 10 days.
What are the symptoms?
H1N1 flu symptoms take some time to develop, it takes around 1 to 3 days in humans. This is after they are exposed to the virus.
If you want to reduce the risk of contracting the influenza virus, it can be done through vaccinations. Consult your doctor if you think you are at a higher risk of acquiring this infection. The need to get vaccinated increases if one is traveling to a place where many cases have been recently reported.
The High-risk groups are:
Children: who are younger than 5 yrs of age, especially those who are younger than 2 yrs
Senior citizens: Those 65 years and older
Pregnant women: who are within 2 weeks of delivery, including those women who have had a miscarriage
Chronic Medical Conditions: People suffering from it. Chronic Medical Conditions like heart disease, diabetes asthma, kidney, liver or blood disease, emphysema and neuromuscular disease
Those who are immunosuppressed (reduction of the activation or efficacy of the immune system) due to some particular medications or because of HIV
How to get it Diagnosed?
If you want to get it diagnosed, it can be done by taking a nose or throat swab. This should be done within the first 5 days of the illness, this being the most infectious period of the disease. Only a few labs are authorized to conduct Swine Flu tests. The Swab results take 8 to 24 hours, after seeing the results and consulting the doctor, the patient will know if he/she has this disease. Some labs are well equipped with a skilled technician if you prefer a home collection of the sample. “The expert team of pathologists is also able to guide clinicians and patients for report analysis and queries surrounding swine flu diagnosis,” mentions ANI report.
Apart from taking vaccines and getting tested for Swine Flu. One of the easiest ways to prevent catching swine flu is by maintaining a basic hygiene routine which includes washing your hands on a regular basis.

Washington: A team of US Engineers which included and Indian origin researcher demonstrated that it is possible to generate Wi-Fi transmissions using 10,000 less power than conventional methods. This is an attempt to save more energy while playing games and doing other things that eat more energy.
The new “Passive Wi-Fi” system also consumes 1,000 times less power than existing energy-efficient wireless communication platforms, such as Bluetooth Low Energy and Zigbee, said computer scientists and electrical engineers from the University of Washington.
“We wanted to see if we could achieve Wi-Fi transmissions using almost no power at all. That is basically what ‘Passive Wi-Fi’ delivers. We can get Wi-Fi for 10,000 times less power than the best thing that’s out there,” said study co-author Shyam Gollakota, assistant professor of computer science and engineering.
“Passive Wi-Fi” can for the first time transmit Wi-Fi signals at bit rates of up to 11 megabits per second that can be decoded on any of the billions of devices with Wi-Fi connectivity. These speeds are lower than the maximum Wi-Fi speeds but 11 times higher than Bluetooth. Apart from saving battery life, wireless communication that uses almost no power will help enable an “Internet of Things” reality where household devices and wearable sensors can communicate using Wi-Fi without worrying about power.
“All the networking, heavy-lifting, and power-consuming pieces are done by the one plugged-in device. The passive devices are only reflecting to generate the Wi-Fi packets, which is a really energy-efficient way to communicate,” explained co-author Vamsi Talla, an electrical engineering doctoral student. To achieve such low-power Wi-Fi transmissions, the team essentially decoupled the digital and analog operations involved in radio transmissions.
The Passive Wi-Fi architecture assigns the analog, power-intensive functions – like producing a signal at a specific frequency — to a single device in the network that is plugged into the wall. An array of sensors produces Wi-Fi packets of information using very little power by simply reflecting and absorbing that signal using a digital switch.
In real-world conditions on the university campus, the team found the passive Wi-Fi sensors and a smartphone can communicate even at distances of 100 feet between them. Because the sensors are creating actual Wi-Fi packets, they can communicate with any Wi-Fi enabled device right out of the box. “Our sensors can talk to any router, smartphone, tablet or other electronic device with a Wi-Fi chipset,” noted electrical engineering doctoral student Bryce Kellogg.
The technology can enable entirely new types of communication that haven’t been possible because energy demands have outstripped available power supplies. It could also simplify our data-intensive worlds. “Now that we can achieve Wi-Fi for tens of microwatts of power and can do much better than both Bluetooth and ZigBee, you could now imagine using Wi-Fi for everything,” said Joshua Smith, associate professor of computer science and engineering.
The technology has also been named one of the 10 breakthrough technologies of 2016 by the journal MIT Technology Review. A paper describing those results will be presented in March at the 13th USENIX Symposium on Networked Systems Design and Implementation in California. (IANS)
