Killer diseases around the world are indeed difficult to halt. Although medical knowledge and advance technologies have made significant improvements and breakthroughs, there are still infectious diseases that continue to ravage and claim millions of lives. Moreover some of these diseases continue to take a heavy toll. HIV-AIDS, diarrhea, malaria, measles, pneumonia, and tuberculosis pass on a disease to million of individuals, killing numerous children and young adults.

These infections result in deaths toll of not less than two-million people annually. One of friend succumbed to diarrhea several years ago, which he took lightly but left him dehydrated eventually die.

Malaria

There are about 300 million people that are infected with this dreaded and deadly disease. About one-million victims die each year. In Africa one child dies of malaria every 30 seconds which is indeed an alarming rate. “Science has no magic bullet for malaria and many doubt that such single solution will ever exist.” According to World Health Organization.

Measles

In 2003, this deadly disease killed over half-million people. One of the leading cause of death among children, measles is vastly contagious. Each year about 30 million people contract measles although effective and cheap vaccine against measles was available for the past four decades.

Around two million children five years below die of pneumonia every year, and most of these deaths take place in Africa and South East Asia. In many parts of the planet, inadequate access to health facilities foils victims from acquiring medical treatments that could’ve save them.

Tuberculosis

In 2003, tuberculosis (TB) caused the death of more than 1.7 million people around the world. The appearance of drug-resistant TB germs is one of the main worries of health officials. Some of these strains have developed resistance to all major anti-TB treatments and medications. Drug-resistant TB strains normally develop in patients who go through poor supervision or have an incomplete medical treatment.
