      The reason why world-renowned organizations like WHO and CDC and Ministry of Health and Family Welfare, Government of India (MoHFW) keep data of these diseases is to improve the longevity of the people. It helps in measuring the quality of healthcare and where the health systems need more medical innovations, and resources the same can be provided in the affected regions.

      For example, the mortality rate in a State or a country can help divert focus towards activities and resources such as transportation, medical infrastructure, food and agriculture, and also the environment.

      Like COVID-19 has put more emphasis on building medical infrastructure and even social interactions. While the pandemic continues to stay and vaccinations being rolled out, we still need to follow all the precautions and also take care of ourselves and our loved ones to keep other deadliest diseases at bay.

      Bottom-line

      Fatalities from certain diseases have increased, while some have reduced in their severity. Most of the diseases in the above list are treatable and preventable. With the advancement in the field of medical science, treatment for all of them is available in India. In the time to come, we may witness a reduction in death rates from these diseases.

      If you follow a good approach and healthy lifestyle you can lower these risks and adapt to a healthy lifestyle and routine exercise. By making small changes in your daily habits like eating right, limiting smoking and drinking you can reduce your vulnerability. For viral infections and bacterial diseases, proper hand hygiene is quite useful in reducing the risk.
