- Chills;
- Headache;
- Cough, sneezing, and runny nose;
- Sore throat;
- Muscle pain, especially in the back and legs;
- Loss of appetite and tiredness.
Usually these symptoms appear suddenly and usually last for 2 to 7 days. In general, the fever lasts about 3 days, while the other symptoms disappear 3 days after the fever subsides.

Flu in pregnant women, children and the elderly
Influenza in pregnant women, children and the elderly can cause stronger symptoms, and can also cause vomiting and diarrhea, as these groups have the weakest immune system, which makes the body more sensitive.

Difference between flu and cold
Unlike the flu, the cold does not cause a fever and usually does not bring complications such as diarrhea, severe headache and difficulty breathing.
In general, the cold lasts for about 5 days, but in some cases the symptoms of runny nose, sneezing and coughing can last up to 2 weeks.
Difference between flu, dengue and zika
