Moderate eating is having food intake in little but nothing in excess which provides all the nutrients in small quantities. A variety of intake of food even provides good nutrition.

Dietary factors are associated with 5 out of 10 leading causes of death like coronary heart diseases, cancers, stroke, type 2 diabetes, and osteoporosis. Globally we are facing an epidemic of overweight and obesity in all ages from children to adults. Along with food intake, it is a necessity to have good physical fitness for the long run of life.

Having HIV treatment is a key aspect of the reduction of global AIDS patients. HIV patients who are aware of this are suggested to take the ART prescribed daily to lessen the viral load, have a better life. Having HIV Continuum helps HIV patients in lowering and suppressing viral content. UNAIDS has set the target as 90% of people with HIV will know the HIV status, 90% will know ART, and 90% ART receiving will have viral suppression.

The deaths caused by AIDS has been reduced to 55% since 2004. Globally, 770,000 people died of HIV in 2018. Despite the advancements of science, there are still a few places where the preventive measures and medication is not available. The global efforts are mounted to address, epidemic.

This process helps in developing the immune system protecting the subsequent infection or disease. This process has proven the ability to controlling the most infectious diseases. This is one of the best methods as part of a prevention step and cost-effective with proved strategies in reaching the populations. This can reach the target groups, have effective delivery to the population. Getting immunized is a better way of eradicating the disease and resulting in healthier and hospital free life from the diseases.

The main risks with the changing climate are heat waves, and extreme conditions, effects on food yields, effects on water bodies, change in patterns of the infectious diseases, impairment if the functioning of the ecosystem, loss of liveliness. Climate change can result in new diseases, with new strains of viruses and other microbes. These may alter the incidence, range, and seasonality of many health issues. Hence adaptive issues must be taken to improve and lessen the health effects. The best preventive measure is to stop the processes affecting climate change. This requires broad insight and bold actions to stop climate change. Health care sectors from its side must take initiative in lessening greenhouse gas emissions.

Unknown Vs. Known diseases

The rise in global temperatures has its worst effects. Malaria, Zika virus, dengue virus, chikungunya, West Nile virus and many more. The mosquito along with the crop-destroying pests are thriving in this warming world. The rise in disease is both familiar as well unknown.
