Halos araw-araw ay marami ang nadagdag na bilang ng naitalang infected sa covid-19, isa sa mga dahilan marahil ay marami pa ring matitigas na ulo na hindi nagpepermi sa kanilang mga tahanan, sa bawat araw na paglabas-labas mo ay di mo malalaman kung sino sa makakasalamuha mo ang carrier ng virus, dahil mayroong tinatawag na asymptomatic na pasyente.
Ang asymptomatic na pasyente ay maaring magkalat ng virus kapag hindi nagsagawa ng self-quarantine, marahil dahil hindi naman nya alam na sya pala ay infected na rin.
Mayroon pang sintomas ang covid-19 na sa ngayon lang din nalaman ng mga eksperto, ito ay ang pagkakaroon ng digestive problem, walang ganang kumain, pagtatae at pagsusuka.
Maliban sa mga nabanggit na sintomas, ang pagkakaroon ng sudden loss of smell at pagkabingi ay pwedeng indikasyon din na infected ang isang tao at pwedeng maging "hidden carrier" ng coronavirus, ayon ito sa ebidensyang nakalap ng leading rhinologists sa UK.
Ayon pa sa Science Alert:
In South Korea, China, and Italy, about a third of patients who have tested positive for COVID-19 have also reported a loss of smell – known as anosmia or hyposmia – leading ear, nose, and throat experts in the UK have reported.
"In South Korea, where testing has been more widespread, 30 percent of patients testing positive have had anosmia as their major presenting symptom in otherwise mild cases," the president of the British Rhinological Society Professor, Clare Hopkins, and the president of the British Association of Otorhinolaryngology, professor Nirmal Kumar, said in a joint statement.
The professors said that many patients around the world who have tested positive for COVID-19 are presenting only the symptoms of loss of smell and taste – without the more commonly recognised symptoms of high fever and coughing.
"There have been a rapidly growing number of reports of a significant increase in the number of patients presenting with anosmia in the absence of other symptoms," the statement says.
"Iran has reported a sudden increase in cases of isolated anosmia, and many colleagues from the US, France, and Northern Italy have the same experience."
