3Stomach flu
Unlike seasonal flu, stomach flu is often caused by some other types of virus, such as rotavirus. In most cases, some symptoms like achiness, fever, watery stools, or vomiting might show up within 2 days after exposure and last for 3 to 8 days. You could generally take care of your stomach flu with some simple home treatment. For the elderly, young children, and those people with a compromised immune system, the risks of dehydration could be higher. Thus, it is necessary to watch for these signs closely and seek immediate treatment in cases of more serious complications. [3]
