India's healthcare sector faces several challenges in achieving universal healthcare coverage. Some of the key challenges are:

• Insufficient funding- The government's healthcare spending is only around 1% of its GDP, which is lower than other developing countries like Brazil and China.
• Shortage of healthcare workers- There is a huge shortage of healthcare workers in India, including doctors, nurses, and paramedical staff.
• Infrastructure deficit- Lack of proper infrastructure facilities such as diagnostic facilities, healthcare institutions, and medical equipment is a major hurdle in providing universal healthcare access.
• Regional disparities- There are significant gaps in the healthcare delivery system in different regions of the country. Rural areas experience a great deficit in basic healthcare, while urban regions have better healthcare facilities.

To overcome these challenges, the government needs to take some proactive measures such as:

• Increasing healthcare spending to at least 2% of India's GDP to provide sufficient funding for the healthcare sector.
• Investing more in healthcare institutions and infrastructure to provide access in remote areas, and incentivizing the private sector to invest in the healthcare sector.
• Encouraging more students to take up medical education, increasing the number of healthcare professionals, and providing incentives to those practicing in rural areas.
• Introducing innovative healthcare technologies such as telemedicine to overcome geographical barriers and improving healthcare access to remote areas.

Overall, by implementing these measures, India can overcome the hurdles and challenges in providing universal healthcare and ensure access to quality healthcare to all its citizens.
