From the following list, select all of the diseases that antibiotics do not directly cure. a. Hanta pulmonary syndrome b. Streptococcus pneumoniae c. Colds d. Influenza e. Haemophilus influenzae f. COVID-19 g. Legionellosis h. Tularemia
Verified step by step guidance
1
Step 1: Understand that antibiotics are drugs designed to kill or inhibit the growth of bacteria, so they are effective against bacterial infections but not viral infections.
Step 2: Identify which diseases in the list are caused by bacteria. For example, Streptococcus pneumoniae, Haemophilus influenzae, Legionellosis, and Tularemia are bacterial infections.
Step 3: Identify which diseases in the list are caused by viruses. For example, Hanta pulmonary syndrome, colds, influenza, and COVID-19 are viral infections.
Step 4: Recognize that antibiotics do not directly cure viral diseases because viruses have different structures and replication mechanisms that antibiotics do not target.
Step 5: Conclude that antibiotics do not directly cure the viral diseases from the list, which include Hanta pulmonary syndrome, colds, influenza, and COVID-19.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Difference Between Bacterial and Viral Infections
Bacterial infections are caused by bacteria and can often be treated with antibiotics, which target bacterial structures or functions. Viral infections, caused by viruses, do not respond to antibiotics because viruses replicate inside host cells and require antiviral drugs or immune responses for treatment.
Antibiotics work by targeting specific bacterial processes such as cell wall synthesis, protein production, or DNA replication. They are ineffective against viruses because viruses lack these bacterial structures and rely on host cell machinery, making antibiotics unsuitable for viral diseases.
Identification of Diseases Caused by Bacteria vs. Viruses
Understanding which diseases are bacterial or viral is essential for treatment decisions. For example, Streptococcus pneumoniae, Haemophilus influenzae, Legionellosis, and Tularemia are bacterial infections treatable with antibiotics, while Hanta pulmonary syndrome, colds, influenza, and COVID-19 are viral and not cured by antibiotics.
