The first major factor which has given rise to life expectancy is the invention of different vaccines for infectious diseases that are present in India and Pakistan. As both the countries are neighbours to each other, unfortunately the diseases are also very common in them too.
Hepatitis B has caused lots death and is still one of the diseases that are very difficult to control. According to oxford dictionary (2014) “hepatitis B is a severe form of viral, it is transmitted in infected blood, causing fever, debility and jaundice.” It is a type of virus that is very dangerous for health of the people. This is supported by WHO (2014) which says “hepatitis B is a significant problem and vaccination saves both money and lives.” Furthermore Dr. Hamid (2013) says “Pakistan alone has 13 million patients of hepatitis out which 4.5 million are hepatitis B patients.” In Pakistan hepatitis B was identified before 1970 where as in India according to Bhatia (2013) cited by times of India “hepatitis B is more infectious than HIV- AIDS.” In addition according to Masand (2013) cited by times of India “80 million people harbour the hepatitis B virus.” This deadly virus is infecting the world but it is a preventable disease. According to WHO (2014) “hepatitis B virus is a vaccine preventable disease but although global control of hepatitis B is achievable, it has not been attained yet.” HB vaccine is the first and currently the only vaccine against this infectious disease. This is also supported by WHO (2014) which says”vaccination is the most effective tool in preventing the transmission of the hepatitis b virus....” however on the other hand governments of both countries are creating awareness amongst the people to use condoms during sexual contact and do not use contaminated needles so that people can prevent themselves from getting infected of hepatitis b virus. Hopefully if this initiative goes successful it is more likely that the people can be saved from getting infected and in the future this disease can reduce.
