Cold, Flu and COVID-19 are all respiratory viruses that may differ in their degree of risks, but are transmitted in the same way. The infectious transmission either takes place in the form of droplets or is airborne in nature. SARS-COV-2, influenza flu or a common cold is spread through large droplets and causes infections in the respiratory route either directly by contact or through a contaminated surface. However, while a cold or a flu fades away in a matter of a few days, COVID can have a long lasting impact.
Vector-borne, monsoon diseases often are accompanied by high-fever, fatigue, joint and muscle pain, which are extremely prevalent in COVID-19 too. Respiratory complications like dry cough, sore throat, loss of sense of smell and taste are all symptoms of COVID-19, which are less likely to be found in dengue patients and those suffering with malaria.
Viral fever and other diseases like typhoid and cholera also trigger fever, muscle and joint pain, fatigue and weakness, chills, dizziness, sweating, dehydration, weakness and loss of appetite, which can occur in COVID-19 patients too.
