<\/div>\n<\/div>\n<\/div>\nThe growing threat of antimicrobial resistance (AMR) has become one of the world’s most pressing public health concerns. According to the World Health Organization (WHO), bacterial antimicrobial resistance (AMR) directly causes nearly 1.27 million deaths every year and contributes to approximately 4.95 million deaths globally. If effective measures are not taken, WHO and global public health agencies project that AMR could contribute to up to 10 million deaths annually by 2050, surpassing deaths from many major diseases. Despite repeated awareness campaigns, antibiotics continue to be misused for viral illnesses such as the common cold, influenza, COVID-19, and dengue. This unnecessary use accelerates antibiotic resistance, making bacterial infections harder, and sometimes impossible, to treat.<\/p>\n People often confuse bacteria and viruses, assuming that antibiotics can treat both. In reality, they are fundamentally different.What are bacteria?<\/span>Bacteria are single-celled living organisms. They possess their own cellular machinery, allowing them to grow, reproduce, and survive independently in suitable environments.<\/p>\n What are viruses?<\/span>Viruses are not considered fully living organisms because they cannot survive or reproduce independently.A virus consists mainly of:<\/p>\n Unlike bacteria, viruses must invade a host cell and hijack its machinery to make copies of themselves.Common viral diseases include:<\/span><\/p>\n Why antibiotics fail against viruses<\/span>Antibiotics target structures or processes found only in bacteria, such as:<\/p>\n Viruses lack these bacterial structures. Since they reproduce using human cells, antibiotics have nothing to attack, making them completely ineffective against viral infections.Instead, viral diseases are treated using:<\/p>\n Understanding how bacteria and viruses behave explains why antibiotics work against one but not the other.How bacteria multiply<\/span>Bacteria reproduce through binary fission, where one bacterial cell divides into two identical daughter cells. During this process:<\/p>\n Antibiotics interrupt one or more of these steps, stopping bacterial growth or killing the bacteria.How viruses multiply<\/span>Viruses cannot reproduce on their own. Their life cycle involves:<\/p>\n Since viruses rely almost entirely on human cells for replication, drugs must target viral proteins without damaging healthy human cells, a much more challenging task than treating bacterial infections.<\/p>\n Antimicrobial resistance occurs when microorganisms evolve so that medicines no longer kill them effectively.AMR includes resistance in:<\/p>\n The most common and serious form is antibiotic resistance.How antibiotic resistance develops<\/span>When antibiotics are used:<\/p>\n Over time, antibiotics become less effective.Major causes<\/span><\/p>\n What are the consequences?<\/span><\/p>\n The WHO considers AMR one of the top global health threats of the 21st century.<\/p>\n World Health Organization (WHO)<\/span>It coordinates the Global Action Plan on Antimicrobial Resistance and promotes rational antibiotic use. The organisation also encourages surveillance of resistant infections worldwide.Food and Agriculture Organization<\/span> (FAO)<\/span>It addresses antibiotic use in agriculture and animal husbandry.World Organisation for Animal Health (WOAH)<\/span>Develops standards for responsible antimicrobial use in animals.United Nations<\/span> (UN)<\/span>In 2016, the UN General Assembly adopted a political declaration recognizing AMR as a major global threat requiring coordinated international action.Global Antimicrobial Resistance and Use Surveillance System (GLASS)<\/span>Launched by WHO to collect standardized global data on antimicrobial resistance and antibiotic consumption.<\/p>\n India carries one of the world’s highest burdens of infectious diseases and is also among the largest consumers of antibiotics.Key initiatives<\/span>National Action Plan on Antimicrobial Resistance (NAP-AMR)Launched in 2017, it focuses on:<\/p>\n Red Line Campaign<\/span>Medicines containing antibiotics carry a red vertical line on their packaging, reminding people that these drugs should only be taken on a doctor’s prescription.Schedule H and Schedule H1 Drugs<\/span>These antibiotics cannot legally be sold without a valid prescription.<\/p>\n Conducts nationwide surveillance and research on resistant bacteria and promotes antibiotic stewardship programmes in hospitals.Challenges in India<\/span><\/p>\n <\/p>\n One Mains Question<\/span>Q. Antimicrobial resistance has emerged as one of the greatest public health challenges of the 21st century. Discuss the causes, consequences and measures adopted globally and by India to combat antimicrobial resistance.MCQs with Answers<\/span>1. Antibiotics are primarily effective against:A. VirusesB. FungiC. BacteriaD. ParasitesAnswer: C2. Which of the following reproduces by binary fission?A. VirusB. BacteriumC. PrionD. ViroidAnswer: B3. Which organisation launched GLASS?A. UNESCOB. WHOC. UNICEFD. FAOAnswer: B4. The Red Line Campaign in India is associated with:A. Blood donationB. VaccinationC. Rational antibiotic useD. HIV awarenessAnswer: C5. Which statement is correct?A. Antibiotics destroy viral envelopes.B. Viruses possess their own metabolism.C. Antibiotics target bacterial structures absent in viruses.D. Viruses divide by binary fission.Answer: CFive Key Terms to Remember<\/span><\/p>\n FAQs<\/span>1. Can antibiotics cure viral fever?<\/span>No. Antibiotics are ineffective against viral infections. Most viral fevers require supportive care unless a specific antiviral drug is available.2. Why do doctors sometimes prescribe antibiotics during viral illnesses?<\/span>If there is evidence or a high risk of a secondary bacterial infection, antibiotics may be prescribed to treat the bacterial infection, not the virus itself.3. What is the difference between antibiotics and antivirals?<\/span>Antibiotics target bacteria by disrupting bacterial structures or functions, whereas antivirals inhibit specific stages of viral replication.4. Why is antibiotic misuse dangerous?<\/span>Misuse promotes antibiotic resistance, making future bacterial infections more difficult to treat and increasing the risk of severe illness and death.5. How can antimicrobial resistance be prevented?<\/span>AMR can be reduced by using antibiotics only when prescribed, completing the full course of treatment, maintaining good hygiene, getting vaccinated, preventing infections, and avoiding the unnecessary use of antibiotics in humans and animals.<\/div>\nThe concept in simple terms<\/h2>\n<\/p>\n
