The correct answer is 1, 2 and 4.

• Communicable diseases are caused by pathogens passed from one human to another.
• Pathogens are viral, bacterial, parasitic and fungal. Methods of transmission include mucus, blood, breath, saliva and sexual contact.
• Contaminated surfaces, such as doorknobs, countertops, and playground equipment, provide a medium for passing disease from one human to another.
• Hence, keeping the surrounding clean, along with clean drinking water facility may protect us from getting a viral or bacterial disease. Hence, Statement 1 is correct.
• Isolating the infected person helped in the recent COVID-19. Hence, Statement 2 is correct.
• Increasing the intake of salt can actually increase the chances of getting a non-communicable disease like cardiovascular disease. Hence, Statement 3 is NOT correct.
• Using only new syringes helps in protecting ourselves from getting in contact with an infected person. Hence, Statement 4 is correct.
