1. The flu is caused by the influenza virus. There are several strains of the virus, including influenza A, B, and C. Influenza viruses can be spread through respiratory droplets from infected individuals, usually through coughing, sneezing, or close contact.
2. Common symptoms of the flu include fever, cough, sore throat, runny or stuffy nose, body aches, headache, fatigue, and sometimes vomiting and diarrhea. Complications that can arise from the flu include pneumonia, bronchitis, sinus and ear infections, and worsening of pre-existing health conditions.
3. Yes, people can misdiagnose themselves with the flu. The symptoms of the flu can mimic those of other respiratory illnesses such as the common cold or even COVID-19. Without a proper diagnosis by a healthcare professional, it can be difficult to differentiate between these illnesses based on symptoms alone. Additionally, self-diagnosis without a medical expert can lead to incorrect treatment or delay in seeking appropriate care.
4. Flu season is defined as a period when the incidence of influenza cases increases significantly. It typically occurs during the winter months in temperate climates, although it can vary geographically. The criteria for determining flu season include monitoring influenza cases, hospitalizations, and deaths, as well as tracking the prevalence of specific influenza strains circulating within a population.
5. The flu can have a significant impact on businesses and governments. Absenteeism due to illness can affect productivity and disrupt operations in workplaces. Governments often implement public health measures such as promoting vaccination, public education campaigns, and monitoring outbreaks to mitigate the spread of the flu. The flu can also put strain on healthcare systems, especially during severe flu seasons. Depending on the severity, certain resources like hospital beds, medical supplies, and antiviral medications could be in higher demand, potentially affecting residents' access to them.
Note: It is important to consult a healthcare professional or refer to the relevant authorities for specific and up-to-date information about the flu.
