what is swine flu and how can we prevent it

Swine flu is a disease of pigs that can, in rare cases, be passed to humans. It is a highly contagious respiratory disease caused by one of many Influenza A viruses. Most commonly, swine flu is of the H1N1 influenza sub type. However, swine flu viruses can sometimes come from other sub types, such as H1N2, H3N1, and H3N2..
The symptoms of swine flu in humans are quite similar to those of regular flu, and include
  • body aches
  • chills
  • cough
  • headache
  • sore throat
  • fever
  • tiredness
  • Less commonly, a person with swine flu may experience vomiting and diarrhea
Symptoms can be managed with similar treatments to regular flu. However, a doctor should examine the patient for confirmation of swine flu and advise how to relief individual symptoms.
The vaccines are very important to prevent 


this diseases:-The Food and Drug Administration (FDA) recently approved the H1N1 vaccine as an injection and an intranasal spray made by CSL, Sanofi Pasteur, MedImmune and Novartis.
The following groups should receive H1N1 vaccine as soon as possible:
  • Pregnant women because they are more likely to develop serious illness and death from H1N1
  • People who live with or care for infants younger than 6 months of age in order to prevent transmission of flu virus from caregivers to infants. Infants are susceptible to developing serious complications from the flu virus
  • Health care and emergency medical personnel because they are at risk for contracting the flu from sick patients and if infected may transmit the virus to patients
  • Anyone from 6 months through 24 years of age because individuals younger than 25 years of age have been infected more often than older people
  • Anyone from 25 through 64 years of age with certain chronic medical conditions or a weakened immune system because chronic conditions reduce the ability of the body to fight diseases


Other groups should be vaccinated as more vaccine becomes available.

you can lose weight

Exercise can certainly help you lose weight by burning calories and building muscle. But, doing just push-ups — even daily — is unlikely to be rigorous enough to burn enough calories to lose a lot of pounds. Push-ups alone also fail to stimulate total-body muscle gains that raise your metabolism and make you a lean machine. To lose weight, the American College of Sports Medicine recommends at least 250 minutes of moderate-intensity cardio exercise weekly. Moderate-intensity exercise is equal to brisk walking or playing a game of doubles tennis. It's unlikely you could fit in 250 minutes of push-ups weekly, and even if you could, this repetition would lead to join pain from overuse. Push-ups are a functional exercise that build stamina and strength in many major muscle groups. Include them as a part of your weight-loss regimen, but not as the sole exercise. Push-Ups Impact on Your Weight Although other factors do come into play, weight loss essentially comes down to crea...

It is mainly found in the tribal areas of Madhya Pradesh, Orissa, West Bengal and Andhra Pradesh. In this metal craft the craftsman firstly subcultures a wax model of the object he wants to make. Then he makes a mould of clay and pours molten metal into a hole in the mould, then the wax melts and the clay is broken away to bring out the metal object which is then smoothed an polished to perfection. This is also know as the lost wax procedure or “cire perdure”. Dokra art mainly produces figurines of Gods, Goddesses and religious animals and birds.

what is the effects of mobile phones on human body

Mobile or cell phones are now a days an integral part of modern telecommunications in every individual life. In many countries, over half of the population use mobile phones and the mobile phone market is growing rapidly. Saudi Arabia rank first among the countries of the gulf region with highest proportion of mobile users, a study conducted by United Nations Conference on Trade and Development (UNCTAD). In gulf countries, Oman ranked second, followed by Kuwait and the UAE. Besides the number of cell phone calls per day, the length of each call and the amount of time people use cell phones are important factors which enhance the health related risk.  In 2011, International Agency for Research on Cancer (IARC) classified mobile phone radiation possibly carcinogenic, means that there “could be some risk” of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted. Mobile phones emit radio frequency energy, a form of non-io...
