10 WAYS YOU KNOW YOUR MOBILE

If you’re among those millions of smart phone users who keep fidgeting with it even when it’s not ringing or vibrating, you’re most likely to suffer from this new disease.According to a report published in the medical journal The Lancet, a 34-year-old female patient in Spain was diagnosed with what they called ‘WhatsAppitis,’ bilateral wrist pain caused by excessive use of the messaging service WhatsApp. The doctor who diagnosed the disease reported that the woman used her mobile to text her family members and friends for a continuous stretch of 6 hours. The next day she got up with severe wrist pain.This is not the first disease or harmful effect of using mobile phones that has been reported. We all are probably so addicted to our phones that we are unknowingly destroying our health. Here are some health risks of cell phones you should be aware of:
1. Cancer: As reported by the World Health Organisation (WHO), mobile phones emit radiofrequency (RF) fields a 1000 times greater than what is emitted from base stations. It’s obvious that this increased emission is likely to have some adverse effect on health of users. Although there is no clear evidence suggesting that exposure to RF fields increases the risk of cancer, but the International Agency for Research on Cancer has classified RF as a possible carcinogen in humans. 
2. Sleep disorders: Somehow night-time has always been favourite among regular chatting and gossiping freaks. But do you know that’s the main reason why you are sleep deprived? Several studies have concluded this. One of them is a cohort study by Sara Thomée et al which found that high mobile phone use was associated with sleep disorders. Major contributing factors to interrupted sleep pattern are getting awakened in the middle of the night due to mobile rings and vibration and increased use of mobiles post-evening until midnight. 
3. Increased accident-risk: Whether you’re an iPhone, flip phone or a Blackberry user, the chances that you check your phone aggressively while travelling is undoubtedly higher. Be it while driving or while crossing the road, mobile phone can be a potential distraction. According to the WHO, we now have a lot of research showing an increased risk of traffic accidents with mobile usage (3-4 times greater). 
4. Heart problems: Radiation from cell phones is not only associated with cancer but also with chronic diseases like heart problems. A study published in European Journal of Oncology, radiations emitted by cordless phones, including mobiles, contribute to abnormalities in heart function. Results reported that radiation causes the red blood cells (RBCs) to seep hemoglobin and lead to heart complications. 
5. Infertility: Beware men! Your phone can even make you infertile. As of now there’s enough evidence to show that mobile phone radiation decreases sperm count in male rats. To identify whether the same holds true in humans, Wdowiak A and colleagues carried out a research which revealed that the group of men who used mobile phones had a decreased sperm cell count in their semen, leading to infertility.
6. Hearing impairment: Today, every alternate person on the street has earphones plugged in. But that’s not the only reason why hearing loss is increasing in youth and adults. Your mobile radiation is an additional factor that’s making you deaf. Long-term exposure to electromagnetic (EM) field from cell phones contributes to reducing hearing function. A study showed that people who attended phone calls for approximately 2 hours every day were at a higher risk of impaired hearing compared to those who moderate users (10-20 mins).
7. Eye problems: A lot of people use their mobiles to read e-books, do web surfing, etc apart from texting. When you do so, the glaring screen and small font size put a lot of strain on your eyes, especially if you’re reading in the dark. Mobile devices have smaller screens so you tend squint or open up your eyes wide open and blink lesser number of times. This can cause dry eyes, irritation and reddening.
8. Skin allergies: Most mobile phones have a typical metallic sheen to make them look more attractive. Such phones contain potential skin allergens like nickel, chromium and cobalt which cause cell phone dermatitis. A study by Marcella Aquino and colleagues tested 72 cell phones for the presence of nickel and cobalt. According to the results, about 29.4% of Blackberry models were tested positive for nickel, 90.5 per cent of flip phones were positive for nickel and about 52% of flip phones had cobalt.
9. Infections: How many of you use your phones in the restroom? Here’s a good reason why you shouldn’t. Cell phones not only serve as a home for your valuable data but also carry millions of infectious organisms. A study found that mobile devices are highly contaminated with organisms from fecal origin. They are a niche for several germs like E.coli (known to cause vomiting and diarrhea) andStaphyloccocus aureus (known to cause skin infections). 
10. Stress: The general desperate nature of people to be available 24/7 on their mobiles is responsible to their exponentially increasing stress levels.

So, the next time you use your mobile phone incessantly, think again!

NEWS: YES, EBOLA CAN BE TRANSMITTED THROUGH SEX AND SALIVA




The Ebola Virus, known as Ebola Virus Disease (EVD), and formerly referred to as Ebola Haemorrhagic Fever is speedily gaining grounds across West Africa. So far, it has reportedly killed 632 people and has had it’s first death case here in Nigeria.



Ebola can be transmitted from human to human. In the Journal of Infectious Diseases, health experts dedicated to research on the virus, made these assertions after several tests:

“Although Ebola virus (EBOV) is transmitted by unprotected physical contact with infected persons, few data exist on which specific bodily fluids are infected or on the risk of fomite transmission. Therefore, we tested various clinical specimens from 26 laboratory-confirmed cases of Ebola hemorrhagic fever, as well as environmental specimens collected from an isolation ward, for the presence of EBOV. Virus was detected by culture and/or reverse-transcription polymerase chain reaction in 16 of 54 clinical specimens (including saliva, stool, semen, breast milk, tears, nasal blood, and a skin swab) and in 2 of 33 environmental specimens.We conclude that EBOV is shed in a wide variety of bodily fluids during the acute period of illness but that the risk of transmission from fomites in an isolation ward and from convalescent patients is low when currently recommended infection control guidelines for the viral hemorrhagic fevers are followed.”
What this clearly means is that the virus can be gotten through unprotected sex and kissing infected people. In addition, if one comes in contact with bodily secretions found on needles, scalpels, soiled clothes and linens, there is high risk of infection.

Other ways one can contact the disease are through contact with a contaminated objects, butchering an infected animal and touching the dead body of someone who has died from the disease.

Fruit bats are also natural hosts of the virus, according to the World Health Organization. For people who enjoy eating bats, they have been warned to desist. Also, researchers believe humans are infected by handling dead or alive infected animals (like chimpanzees, gorillas and forest antelopes). People are advised to avoid bush meat.

Ebola Kills
Out of the 410 suspected and confirmed cases of Ebola in Guinea, 310 suspected deaths have occurred. Of the 196 suspected and confirmed cases in Liberia, 116 suspected deaths have occurred. Of 442 suspected and confirmed cases in Sierra Leone, 206 suspected deaths have occurred. Ebola kills 80 to 90 percent of the time, says Encyclopaedia Britannica.

Diagnosis is Hard in the Early Stages
Because the first symptoms of Ebola could be signs of other conditions like skin rash and red eyes, it is usually hard to diagnose. However, tests can be run in a hospital.

General Symptoms
Fever
Headache
Joint and muscle aches
Weakness
Diarrohea
Vomiting
Stomach pain
Lack of appetite

Some patients sometimes experience:
A Rash
Red Eyes
Hiccups
Cough
Sore throat
Chest pain
Difficulty breathing
Difficulty swallowing
Haemorrhaging inside and outside of the body

Symptoms sometimes appear from 2 to 21 days after a person gets infected but the most common is 8-10 days.

Ebola Has no Cure or Vaccine
Treatments and vaccines are being tested right now but so far, nothing has been made available for the cure or prevention of Ebola. There is only supportive therapy for infected persons and this consists of maintaining blood pressure and oxygen levels, and maintaining adequate fluid and electrolyte balance.

Some People Do Recover From Ebola
The percentage of recoveries is very low, most times just 1 out of 10 reported cases makes it out alive. It is yet uncertain why some people are able to fight it and others cannot.

How to Prevent Infection of Ebola

The Guardian listed out the following measures:
Avoid direct and indirect contact with bodily fluids and tissue of infected persons.
Frequent Hand-washing and use of hand sanitizer.
Fruits and vegetables must be washed properly before eating; avoid bush meat and even suya, which the source is not known.
Avoid shaking of hands and hugging of people, at least for now.
Practise safe sex
Watch children and even adults to discourage them from licking their fingers before washing. Nail biting should be avoided.
The use of gloves and appropriate personal protective equipment must be used in taking care of ill patients. Proper handling of corpses, which may involve a modification of burial practices, is also a preventive step.

Are Countries Outside West Africa at Risk?
Earlier this year, a woman flying into Canada from Congo fell ill and was hospitalized. News soon spread that she had contacted the virus, even though she hadn't. There have not been any reported cases but people feel the disease is only a plane ride away, just the same way it got into Nigeria.

“It is not impossible that an Ebola outbreak could occur in North America", says Ann Marie Kimball, an epidemiologist with the School of Public Health at the University of Washington, Seattle. “We live in an age in which the travel time is shorter than the incubation for a disease. You can get infected, go on a plane for 13 or 14 hours and still have two to three days to get sick.”

Historically, Kimball adds that people would travel by ship and their symptoms would show up by the time they reached port and they could be quarantined. But its is not the same with air trips “Given travel time today, we may see an increasing number of people becoming ill when they arrive in this country, which makes disease control impossible.”

“The possibility that this deadly virus has reached North America focuses attention on the need to fortify our ability to detect and handle outbreaks of infectious diseases,” Sen. Patrick Leahy, D-Vt., the ranking member of the Senate Appropriations Subcommittee on Foreign Operations, said in a statement.

“It is only a matter of time before the Ebola virus reaches North America, whether this time or the next. Any infectious disease — even the world’s most deadly virus — is only an airplane flight away from our shores.”

For now, the best way to avoid being infected is to employ all measures to keep yourself protected.
